Getting Started 1 To connect the oscilloscope probes Input impedance is selectable: 1 MΩ or 50 Ω. Press the channel on/off key (see page 46), then press the Imped softkey to select the input impedance. The 1 MΩ mode is for use with many passive probes and for general purpose measurements. The high impedance minimizes the loading effect of the oscilloscope on the circuit under test. The 50 Ω mode matches 50 Ω cables and some active probes commonly used in making high frequency measurements.
1 Getting Started WA R N I N G Do not negate the protective action of the ground connection to the oscilloscope. The oscilloscope must remain grounded through its power cord. Defeating the ground creates an electric shock hazard. CAUTION Maximum input voltage for analog inputs CAT I 300 Vrms, 400 Vpk; transient overvoltage 1.
Getting Started 1 To verify basic oscilloscope operation To verify that you can display a signal on the oscilloscope: 1 Press the Save/Recall key on the front panel, then press the Default Setup softkey. (The softkeys are located directly below the display on the front panel.) The oscilloscope is now configured to its default settings. 2 Connect an oscilloscope probe from channel 1 to the Probe Comp signal terminal on the front panel.
1 Getting Started To compensate the oscilloscope probes You should compensate your oscilloscope probes to match their characteristics to the oscilloscope’s channels. A poorly compensated probe can introduce measurement errors. To compensate the N2863A probes, follow the procedure that was supplied with the probes. To compensate the 10073C probes, use the procedure that was supplied with the probes or the following procedure. 1 Perform the procedure “To verify basic oscilloscope operation” on page 37.
Getting Started 1 To calibrate the probes The oscilloscope can accurately calibrate its oscilloscope channels to certain active probes, such as InfiniiMax probes. Other probes, such as the 10073C and N2863A passive probes, do not require calibration. The Calibrate Probe softkey will be grayed-out (ghosted; displayed in faint text) when a connected probe does not require calibration.
1 Getting Started Active Probes Supported Active probes that do not have their own external power supply require substantial power from the AutoProbe interface. “Quantity Supported” indicates the maximum number of each type of active probe that can be connected to the oscilloscope. If too much current is drawn from the AutoProbe interface, an error message will be displayed, indicating that you must momentarily disconnect all probes to reset the AutoProbe interface.

Front-Panel Controls 2 2-Channel InfiniiVision 5000 Series Oscilloscope Front Panel (differences only) External Trigger Input Figure 2 InfiniiVision 5000 Series 2-Channel Oscilloscope Front Panel The differences between the front panel of the 4-channel oscilloscopes and the 2-channel oscilloscopes are: • The 2-channel oscilloscope has two sets of channel controls • The 2-channel oscilloscope’s external trigger input is on the front panel instead of the rear panel. Some trigger features differ.
2 Front-Panel Controls Interpreting the display The oscilloscope display contains acquired waveforms, setup information, measurement results, and softkeys for setting up parameters.
Front-Panel Controls 2 Front-Panel Operation This section provides a brief overview of operating the front-panel controls. Detailed oscilloscope operating instructions are provided in later chapters. To adjust the waveform intensity The Intensity control is at the lower left corner of the front panel near the power switch. • Rotate the Intensity control clockwise to increase the intensity of displayed waveforms, or counter-clockwise to decrease intensity.
2 Front-Panel Controls • When you press the Run/Stop key again, it illuminates in red, and the oscilloscope is stopped. “Stop” is displayed in the trigger mode position in the status line at the top of the display. You can pan and zoom the stored waveform by turning the horizontal and vertical control knobs. • When controlling the oscilloscope through its Web interface (see Remote Front Panel on page 29) select Run Control from the Main Menu or press ctrl+R for run/stop or ctrl+S for single.
Front-Panel Controls 2 To make a single acquisition When you press the Single key it illuminates in yellow and the oscilloscope starts the acquisition system, searching for the trigger condition. When the trigger condition is met, the captured waveform is displayed, the Single key is extinguished and the Run/Stop key illuminates in red. • Use the Single key to view single-shot events without subsequent waveform data overwriting the display.
2 Front-Panel Controls trigger mode to Auto (see page 92) and press the Single key. If a trigger condition occurs within about 40 ms, it will be used; if a trigger doesn’t occur, an untriggered acquisition will be taken. To pan and zoom You can pan across and zoom-in on a waveform even when the acquisition system is stopped. 1 Press the Run/Stop key to stop acquisitions (or press the Single key and allow the oscilloscope to acquire the waveform and stop).
Front-Panel Controls 2 In many cases, a triggered display is not needed to check signal levels or activity. For these applications, use Auto trigger mode (which is the default setting). If you only want to acquire specific events as specified by the trigger settings, use Normal trigger mode. You can select the trigger mode by pressing the Mode/Coupling key, then the Mode softkey. For more detailed discussion of Auto trigger mode and Normal trigger mode, see “Trigger modes: Normal and Auto” on page 92.
2 Front-Panel Controls default configuration by pressing the Save/Recall key, then the Default Setup softkey. Then press the AutoScale key. You should see a display similar to the one shown below. Figure 4 AutoScale of oscilloscope channels 1 and 2 If the waveforms are not perfectly square, you may need to set the probe compensation as described on page 38.

3 Triggering the Oscilloscope The Agilent InfiniiVision 5000 Series oscilloscopes provide a full set of features to help automate your measurement tasks. MegaZoom technology lets you capture and examine untriggered waveforms. With these oscilloscopes you can: • Modify the way the oscilloscope acquires data. • Set up simple or complex trigger conditions as needed, to capture only the sequence of events you want to examine.
Triggering the Oscilloscope 3 Selecting Trigger Modes and Conditions The trigger mode affects the way in which the oscilloscope searches for the trigger. The figure below shows the conceptual representation of acquisition memory. Think of the trigger event as dividing acquisition memory into a pre-trigger and post-trigger buffer. The position of the trigger event in acquisition memory is defined by the time reference point and the horizontal position setting.
3 Triggering the Oscilloscope Trigger modes: Normal and Auto An introduction to Normal and Auto trigger modes is given on page 56. 1 Press the Mode/Coupling key. 2 Press the Mode softkey, then select Normal or Auto. • Normal mode displays a waveform when the trigger conditions are met, otherwise the oscilloscope does not trigger and the display is not updated. • Auto mode is the same as Normal mode, except it forces the oscilloscope to trigger if the trigger conditions are not met.
Triggering the Oscilloscope 3 Normal mode Use Normal trigger mode for low repetitive-rate signals or when Auto trigger is not required. In Normal mode the oscilloscope must fill the pre-trigger buffer with data before it will begin searching for a trigger event. The trigger mode indicator on the status line flashes Trig’d? to indicate the oscilloscope is filling the pre-trigger buffer.
3 Triggering the Oscilloscope To select trigger Coupling 1 Press the Mode/Coupling key. 2 Press the Coupling softkey, then select DC, AC, or LF Reject coupling. • DC coupling allows DC and AC signals into the trigger path. • AC coupling places a 10 Hz high-pass filter in the trigger path removing any DC offset voltage from the trigger waveform. The high-pass filter in the External Trigger input path is 3.5 Hz for all models.
Triggering the Oscilloscope 3 • HF Reject adds a 50 kHz low-pass filter in the trigger path to remove high frequency components from the trigger waveform. You can use HF Reject to remove high-frequency noise, such as AM or FM broadcast stations or noise from fast system clocks, from the trigger path. To set Holdoff 1 Press the Mode/Coupling key. 2 Turn the Entry knob to increase or decrease the trigger holdoff time shown in the Holdoff softkey.
3 Triggering the Oscilloscope Holdoff Operating Hints Holdoff keeps a trigger from occurring until after a certain amount of time has passed since the last trigger. This feature is valuable when a waveform crosses the trigger level multiple times during one period of the waveform. Without holdoff, the oscilloscope could trigger on each of the crossings, producing a confusing waveform. With holdoff set correctly, the oscilloscope always triggers on the same crossing.
Triggering the Oscilloscope 3 The External Trigger input The External Trigger input can be used as a source in several of the trigger types. On 2-channel oscilloscopes, the external trigger BNC input is on the front panel and is labeled Ext Trigger. On 4-channel oscilloscopes, the external trigger BNC input is on the rear panel and is labeled Ext Trig. 2-Channel oscilloscope External Trigger input External Trigger Probe Settings You can set external trigger probe parameters as described below.
3 Triggering the Oscilloscope When you connect an AutoProbe self-sensing probe, the oscilloscope will automatically configure your probe to the correct attenuation factor. The probe correction factor must be set properly for measurements to be made correctly. Range The input voltage range can be set to 1.0 Volts or 8.0 Volts. When in current mode, the range is fixed at 1.0 Amps. Range is automatically scaled according to the probe’s attenuation factor.
Triggering the Oscilloscope 3 Input Impedance The external trigger input impedance can be set to either 1M Ohm or 50 Ohm by pressing the Imped softkey. • 50 Ohm mode matches 50-ohm cables commonly used in making high frequency measurements. This impedance matching gives you the most accurate measurements since reflections are minimized along the signal path. • 1M Ohm mode is for use with many passive probes and for general-purpose measurements.
3 Triggering the Oscilloscope Trigger Types The oscilloscope lets you synchronize the display to the actions of the circuit under test by defining a trigger condition. You can use any input channel or the Ext Trigger BNC as the source for most trigger types. MegaZoom Technology Simplifies Triggering With the built-in MegaZoom technology, you can simply AutoScale the waveforms, then stop the oscilloscope to capture a waveform.
Triggering the Oscilloscope 3 To use Edge triggering The Edge trigger type identifies a trigger by looking for a specified edge (slope) and voltage level on a waveform. You can define the trigger source and slope in this menu. The slope can be set to rising edge, falling edge, or alternating edges on all sources except Line. The trigger type, source, and level are displayed in the upper-right corner of the display.
3 Triggering the Oscilloscope You can select oscilloscope channel 1 or 2, Ext, or Line as the trigger source on any Agilent InfiniiVision 5000 Series oscilloscope. The trigger source can also be set to channel 3 and 4 on 4-channel oscilloscopes. You can choose a channel that is turned off (not displayed) as the source for the edge trigger.
Triggering the Oscilloscope 3 To use Pulse Width triggering Pulse Width (glitch) triggering sets the oscilloscope to trigger on a positive or negative pulse of a specified width. If you want to trigger on a specific timeout value, use Duration trigger in the Trigger More menu. 1 Press the Pulse Width key in the Trigger section of the front panel to display the Pulse Width trigger menu.
3 Triggering the Oscilloscope The selected pulse polarity is displayed in the upper-right corner of the display. A positive pulse is higher than the current trigger level or threshold and a negative pulse is lower than the current trigger level or threshold. When triggering on a positive pulse, the trigger will occur on the high to low transition of the pulse if the qualifying condition is true.
Triggering the Oscilloscope 3 • 2 ns to 10 s for > or < qualifier (5 ns to 10 s for 100 MHz and 300 MHz bandwidth models) • 10 ns to 10 s for >< qualifier, with minimum difference of 5 ns between upper and lower settings < qualifier time set softkey • When the less than (<) qualifier is selected, the Entry knob sets the oscilloscope to trigger on a pulse width less than the time value displayed on the softkey.
3 Triggering the Oscilloscope To use Pattern triggering The Pattern trigger identifies a trigger condition by looking for a specified pattern. This pattern is a logical AND combination of the channels. Each channel can have a value of high (1), low (0), or don't care (X). A rising or falling edge can be specified for one channel included in the pattern. 1 Press the Pattern key in the Trigger section of the front panel to display the Pattern trigger menu.
Triggering the Oscilloscope 3 Adjust the trigger level for the selected channel by turning the Trigger Level knob. The value of the trigger level is displayed in the upper-right corner of the display. 3 For each channel you select, press one of the condition softkeys to set the condition for that channel in the pattern. • 0 sets the pattern to low on the selected channel. A low is a voltage level that is less than the channel's trigger level or threshold level.
3 Triggering the Oscilloscope To use CAN triggering NOTE For CAN decode setup see page 226. Controller Area Network (CAN) trigger will trigger on CAN version 2.0A and 2.0B signals. Setup consists of connecting the oscilloscope to a CAN signal, using the Settings menu to specify the event to trigger on, and using the Signals menu to specify the signal source, baud rate, and sample point. The oscilloscope will trigger on dominant-low CAN signals.

3 Triggering the Oscilloscope To use I2C triggering NOTE For I2C decode setup see page 217. An I2C (Inter-IC bus) trigger setup consists of connecting the oscilloscope to the serial data (SDA) line and the serial clock (SCL) line, then triggering on a stop/start condition, a restart, a missing acknowledge, an EEPROM data read, or on a read/write frame with a specific device address and data value.
Triggering the Oscilloscope 3 2 Press the Signals softkey to display the I2C signals menu. SCL Clock channel SDA Data channel Return to previous menu 3 Connect an oscilloscope channel to the SCL (serial clock) line in the circuit under test, then set the SCL clock channel softkey to that channel.
3 Triggering the Oscilloscope Data needs to be stable during the whole high clock cycle or it will be interpreted as a start or stop condition (data transitioning while the clock is high). 6 Return to the previous menu; then, press the Trigger: softkey to select one of the following I2C trigger conditions: • Start Condition — The oscilloscope triggers when SDA data transitions from high to low while the SCL clock is high.
Triggering the Oscilloscope 3 • EEPROM Data Read — The trigger looks for EEPROM control byte value 1010xxx on the SDA line, followed by a Read bit and an Ack bit. It then looks for the data value and qualifier set by the Data softkey and the Data is softkey. When this event occurs, the oscilloscope will trigger on the clock edge for the Ack bit after the data byte. This data byte does not need to occur directly after the control byte.
3 Triggering the Oscilloscope • Frame (Start: Addr7: Read: Ack: Data: Ack: Data2) or Frame (Start: Addr7: Write: Ack: Data: Ack: Data2) — The oscilloscope triggers on a read or write frame in 7-bit addressing mode on the 26th clock edge if all bits in the pattern match. For triggering purposes, a restart is treated as a start condition.
Triggering the Oscilloscope 3 Press the Data is softkey to set the oscilloscope to trigger when data is = (equal to), ≠ (not equal to), < (less than), or > (greater than) the data value set in the Data softkey. The oscilloscope will trigger on the clock edge for the Ack bit after the trigger event is found. This data byte does not need to occur directly after the control byte.
3 Triggering the Oscilloscope To use LIN triggering NOTE For LIN decode information see page 233. LIN (Local Interconnect Network) trigger setup consists of connecting the oscilloscope to a serial LIN signal. LIN triggering will trigger on the rising edge at the Sync Break exit of the LIN single-wire bus signal that marks the beginning of the message frame. If the N5424A CAN/LIN Automotive Triggering and Decode option is installed on your oscilloscope, the Frame ID trigger type will also be available.

4 Making Measurements The figure below shows an example of multiply.
Making Measurements 4 Subtract When you select 1 – 2, channel 2 voltage values are subtracted from channel 1 voltage values point by point, and the result is displayed. You can use 1 – 2 to make a differential measurement or to compare two waveforms. You may need to use a true differential probe if your waveforms have DC offsets larger than the dynamic range of the oscilloscope's input channel.
4 Making Measurements The figure below shows an example of subtract.
Making Measurements 4 Differentiate d/dt (differentiate) calculates the discrete time derivative of the selected source. You can use differentiate to measure the instantaneous slope of a waveform. For example, the slew rate of an operational amplifier may be measured using the differentiate function. Because differentiation is very sensitive to noise, it is helpful to set acquisition mode to Averaging in the Acquire menu.
4 Making Measurements • Offset —lets you set your own offset for the dV/dt math function. The offset value is in units/second where units can be V (Volts), A (Amps), or W (Watts) and is represented by the center horizontal grid line of the display. Press the Offset softkey, then turn the Entry knob to change the offset for d/dt.

Making Measurements 4 FFT Measurement FFT is used to compute the fast Fourier transform using oscilloscope input channels or math functions 1 + 2, 1 – 2, or 1 * 2. FFT takes the digitized time record of the specified source and transforms it to the frequency domain. When the FFT function is selected, the FFT spectrum is plotted on the oscilloscope display as magnitude in dBV versus frequency.
4 Making Measurements vertical bandwidth when making FFT measurements. The FFT sample rate is displayed directly above the softkeys when the FFT menu is displayed. Aliasing happens when there are frequency components in the signal higher than half the sample rate. Since the FFT spectrum is limited by this frequency, any higher components are displayed at a lower (aliased) frequency. The following figure illustrates aliasing. This is the spectrum of a 990 Hz square wave, which has many harmonics.
Making Measurements 4 Spectral Leakage The FFT operation assumes that the time record repeats. Unless there is an integral number of cycles of the sampled waveform in the record, a discontinuity is created at the end of the record. This is referred to as leakage. In order to minimize spectral leakage, windows that approach zero smoothly at the beginning and end of the signal are employed as filters to the FFT. The FFT menu provides three windows: Hanning, flattop, and rectangular.
4 Making Measurements • Center — sets the FFT spectrum frequency represented at the center vertical grid line of the display. It is possible to set the Center to values below half the span or above the maximum available frequency, in which case the displayed spectrum will not take up the whole screen. Press the Center softkey, then turn the Entry knob to set the desired center frequency of the display.
Making Measurements 4 . Scale and offset considerations If you do not manually change the FFT scale or offset settings, when you turn the horizontal sweep speed knob, the span and center frequency settings will automatically change to allow optimum viewing of the full spectrum. If you do manually set scale or offset, turning the sweep speed knob will not change the span or center frequency settings, allowing you see better detail around a specific frequency.
4 Making Measurements The following FFT spectrum was obtained by connecting the front panel Probe Comp signal (~1.2 kHz) to channel 1. Set sweep speed to 5 ms/div, vertical sensitivity to 500 mV/div, Units/div to 10 dBV, Offset to -34.0 dBV, Center frequency to 5.00 kHz, frequency Span to 10.0 kHz, and window to Hanning. Figure 25 FFT measurements FFT Measurement Hints The number of points acquired for the FFT record is 1000 and when frequency span is at maximum, all points are displayed.
Making Measurements 4 Decreasing the effective sampling rate by selecting a slower sweep speed will increase the low frequency resolution of the FFT display and also increase the chance that an alias will be displayed. The resolution of the FFT is the effective sample rate divided by the number of points in the FFT. The actual resolution of the display will not be this fine as the shape of the window will be the actual limiting factor in the FFTs ability to resolve two closely space frequencies.
4 Making Measurements Square Root √ (square root) calculates the square root of the selected source. In Zoom mode, the √ (square root) function does not display in the zoomed portion of the display. 1 Press the Math key, press the √ (square root) softkey, then press the Source, Scale, or Offset sofkeys if you want to change the source, scaling, or offset for the square root function. • Source — selects the source for √ (square root).
Making Measurements 4 The figure below shows an example of √ (square root).
4 Making Measurements Cursor Measurements You can measure waveform data using cursors. Cursors are horizontal and vertical markers that indicate X-axis values (usually time) and Y-axis values (usually voltage) on a selected waveform source. The position of the cursors can be moved by turning the Entry knob. When you press the Cursors key, it will illuminate and the cursors will turn on. To turn cursors off, press this key again until it is not illuminated, or press the Quick Meas key.
Making Measurements 4 • Binary — Binary logic levels are displayed directly above the softkeys for the current X1 and X2 cursor positions for all displayed channels. Cursor X1 values for channels 1 through 4 Indicates left bit is channel 1, right bit is channel 4 • Hex — Hexadecimal logic levels are displayed directly above the softkeys for the current X1 and X2 cursor positions for all displayed channels.
4 Making Measurements 4 Select the X and Y softkeys to make a measurement. • X Y — Press this softkey to select either X cursors or Y cursors for adjustment. The cursor currently assigned to the Entry knob displays brighter than the other cursors. X cursors are vertical dashed lines that adjust horizontally and normally indicate time relative to the trigger point. When used with the FFT math function as a source, the X cursors indicate frequency.
Making Measurements 4 Turn the Entry knob to adjust the Y1 or Y2 cursor when its softkey is selected. • X1 X2 — Press this softkey to adjust the X1 and X2 cursors together by turning the Entry knob. The ∆X value will remain the same since the cursors adjust together. You can adjust the X cursors together to check for pulse width variations in a pulse train. • Y1 Y2 — Press this softkey to adjust the Y1 and Y2 cursors together by turning the Entry knob.

Making Measurements 4 To make an automatic measurement A brief description of how to make automatic measurements is given on page 73. Quick Meas makes automatic measurements on any channel source or any running math function. The results of the last four measurements selected are displayed on the dedicated line above the softkeys, or in the display area when some menus are selected. Quick Meas also makes measurements on stopped waveforms when you are panning and zooming.
4 Making Measurements 3 Press the Clear Meas softkey to stop making measurements and to erase the measurement results from the display line above the softkeys. When Quick Meas is pressed again, the default measurements will be Frequency and Peak-Peak. 4 Press the Select softkey then rotate the Entry knob to select a measurement to be made. 5 The Settings softkey will be available to make additional measurement settings on some measurements. 6 Press the Measure softkey to make the measurement.
Making Measurements 4 thresholds. Each oscilloscope channel can be assigned unique threshold values. Source select Threshold Type Lower Threshold Middle Threshold Upper Threshold Return to previous menu 3 Press the Type softkey to set the measurement threshold to % (percentage of Top and Base value) or to Absolute (absolute value.) • Percentage thresholds can be set from 5% to 95%. • The units for absolute threshold for each channel is set in the channel probe menu.
4 Making Measurements • If threshold Type is set to %, the middle threshold value can be set from 6% to 94%. 6 Press the Upper softkey, then turn the Entry knob to set the upper measurement threshold value. Decreasing the upper value below the set middle value will automatically decrease the middle value to be less than the upper value. The default upper threshold is 90% or 1.50 V. • If threshold Type is set to %, the upper threshold value can be set from 7% to 95%.
Making Measurements 4 Counter The InfiniiVision 5000 Series oscilloscopes have an integrated 5-digit hardware frequency counter which counts the number of cycles that occur within a period of time (known as the gate time) to measure the frequency of a signal. The gate time for the Counter measurement is automatically adjusted to be 100 ms or twice the current time window, whichever is longer, up to 1 second. The Counter can measure frequencies up to the bandwidth of the oscilloscope.
4 Making Measurements To isolate an event for frequency measurement The following figure shows how to use zoom sweep to isolate an event for a frequency measurement. If the measurement is not possible in the zoom mode, then the main time base is used. If the waveform is clipped, it may not be possible to make the measurement. Figure 32 Isolating event for Frequency measurement Period Period is the time period of the complete waveform cycle.
Making Measurements 4 the sweep speed as fast as possible while leaving the complete falling edge of the waveform on the display. The Y cursors show the lower and upper threshold points. Rise Time The rise time of a signal is the time difference between the crossing of the lower threshold and the crossing of the upper threshold for a positive-going edge. The X cursor shows the edge being measured.
4 Making Measurements Maximum units are in dB and X at Max units are in Hertz for FFT. X at Min X at Min is the X axis value (usually time) at the first displayed occurrence of the waveform Minimum, starting from the left-side of the display. For periodic signals, the position of the minimum may vary throughout the waveform. The X cursor shows where the current X at Min value is being measured.
Making Measurements 4 The following example shows a delay measurement between the rising edge of channel 1 and the rising edge of channel 2. Figure 33 Delay Measurement Phase Phase is the calculated phase shift from source 1 to source 2, expressed in degrees. Negative phase shift values indicate that the rising edge of source 1 occurred after the rising edge of source 2.
4 Making Measurements 1 Press the Settings softkey to select the source 1 and source 2 channels for the phase measurement. The default Phase settings measure from channel 1 to channel 2. The example below shows a phase measurement between the channel 1 and the math d/dt function on channel 1.
Making Measurements 4 Voltage Measurements Measurement units for each input channel can be set to Volts or Amps using the channel Probe Units softkey. A scale unit of U (undefined) will be displayed for math function 1-2 and for d/dt, and ∫ dt when 1-2 or 1+2 is the selected source if channel 1 and channel 2 are set to dissimilar units in the channel Probe Units softkey.
4 Making Measurements Amplitude The Amplitude of a waveform is the difference between its Top and Base values. The Y cursors show the values being measured. Average Average is the sum of the waveform samples divided by the number of samples over one or more full periods. If less than one period is displayed, Average is calculated on the full width of the display. The X cursors show what portion of the displayed waveform is being measured.
Making Measurements 4 RMS RMS (DC) is the root-mean-square value of the waveform over one or more full periods. If less than one period is displayed, RMS (DC) average is calculated on the full width of the display. The X cursors show what interval of the waveform is being measured.
4 Making Measurements mean -3s -2s -1s 0 1s 2s 3s 68.3% 95.4% 99.7% The mean is calculated as follows: N ∑ xi =1 x = i------------N where: x = the mean. N = the number of measurements taken. xi = the ith measurement result. The standard deviation is calculated as follows: N ∑ ( xi – x ) σ = 2 i=1 ----------------------------N–1 where: σ = the standard deviation. N = the number of measurements taken. xi = the ith measurement result. x = the mean.
Making Measurements 4 Top The Top of a waveform is the mode (most common value) of the upper part of the waveform, or if the mode is not well defined, the top is the same as Maximum. The Y cursor shows the value being measured. To isolate a pulse for Top measurement The following figure shows how to use zoom to isolate a pulse for a Top measurement.
4 Making Measurements Overshoot and Preshoot Measurements Preshoot Preshoot is distortion that precedes a major edge transition expressed as a percentage of Amplitude. The X cursors show which edge is being measured (edge closest to the trigger reference point).
Making Measurements 4 Overshoot Overshoot is distortion that follows a major edge transition expressed as a percentage of Amplitude. The X cursors show which edge is being measured (edge closest to the trigger reference point).

5 Displaying Data Pan and Zoom The ability to pan (move horizontally) and zoom (expand or compress horizontally) an acquired waveform is important because of the additional insight it can reveal about the captured waveform. This additional insight is often gained from seeing the waveform at different levels of abstraction. You may want to view both the big picture and the specific little picture details.
Displaying Data 5 The ∇ symbol at the top of the display indicates the time reference point where the zoom-in/zoom-out is referenced. 3 Turn the Horizontal Position knob ( ) to pan horizontally and turn the channel’s vertical position knob ( ) to pan vertically. The stopped display may contain several triggers worth of information, but only the last trigger acquisition is available for pan and zoom.
5 Displaying Data Antialiasing At slower sweep speeds, the sample rate is reduced and a proprietary display algorithm is used to minimize the likelihood of aliasing. By default, Antialiasing is enabled. You should leave Antialiasing enabled unless there is a specific reason to switch it off. If you need to switch Antialiasing off, press Utilities&Options&Preferences and press the Antialiasing softkey to switch the feature off. The displayed waveforms will be more susceptible to aliasing.
Displaying Data 5 Display Settings • Press the Display key to view the Display menu. Infinite persistence With infinite persistence, the oscilloscope updates the display with new acquisitions, but does not erase the results of previous acquisitions. All previous acquisitions are displayed in gray with reduced intensity, New acquisitions are shown in normal color with normal intensity. Waveform persistence is not kept beyond the display area boundary.
5 Displaying Data Accumulating multiple acquisitions Turning off infinite persistence does not clear the display. This allows you to accumulate multiple acquisitions, stop acquisitions, and then compare future acquisitions to the stored waveforms. Clearing stored infinite persistence waveforms In addition to clearing the display by pressing the Clear Display softkey, the display is also cleared of previous acquisitions if you press the AutoScale key.
Displaying Data 5 Using Vectors (Display menu) One of the most fundamental choices you must make about your display is whether to draw vectors (connect the dots) between the samples, or simply let the samples fill in the waveform. To some degree, this is a matter of personal preference, but it also depends on the waveform. • You will probably operate the oscilloscope most often with vectors on. Complex analog signals like video and modulated signals show analog-like intensity information with vectors on.
5 Displaying Data Varying the intensity to view signal detail The Intensity knob lets you adjust the plotted waveforms to account for various signal characteristics, such as fast sweep speeds and low trigger rates. Increasing the intensity lets you see the maximum amount of noise and infrequently occurring events. Reducing the intensity can expose more detail in complex signals as shown in the following figures.
Displaying Data 5 Acquisition Modes The InfiniiVision 5000 Series oscilloscopes have the following acquisition modes: • Normal — for most waveforms (with normal decimating at slower sweep speeds, no averaging). • Peak Detect — for displaying narrow pulses that occur infrequently (at slower sweep speeds). • Averaging — for reducing noise and increasing resolution (at all sweep speeds, without bandwidth or rise time degradation). • High Resolution — for reducing random noise (at slower sweep speeds).
5 Displaying Data Normal Mode In Normal mode at slower sweep speeds, extra samples are decimated (in other words, some are thrown away). This mode yields the best display for most waveforms. Peak Detect Mode In Peak Detect mode at slower sweep speeds, minimum and maximum samples are kept in order to capture infrequent and narrow events (at the expense of exaggerating any noise). This mode displays all pulses that are at least as wide as the sample period (see Table 9).
Displaying Data 5 High Resolution mode can be used on both single-shot and repetitive signals and it does not slow waveform update because the computation is done in the MegaZoom custom ASIC. High Resolution mode limits the scope's real-time bandwidth because it effectively acts like a low-pass filter.
5 Displaying Data To use the Averaging mode 1 Press the Acquire key, then press the Acq Mode softkey until the Averaging mode is selected. 2 Press the #Avgs softkey and turn the Entry knob to set the number of averages that best eliminates the noise from the displayed waveform. The number of acquisitions being averaged is displayed in the # Avgs softkey.
Displaying Data Figure 40 5000 Series Oscilloscope User’s Guide 5 128 Averages used to reduce random noise 213
5 Displaying Data Realtime Sampling Option Realtime sampling specifies that the oscilloscope produce the waveform display from samples collected during one trigger event (that is, one acquisition). Use Realtime sampling to capture infrequent triggers, unstable triggers, or complex changing waveforms, such as eye diagrams. Realtime sampling can be turned on in Normal, Peak Detect, or High Resolution acquisition modes. It cannot be turned on when the acquisition mode is Averaging.
Displaying Data 5 Whenever both channels in a channel pair are on, the sample rate for all channels is halved. For example, when channels 1, 2, and 3 are on, the sample rate for all channels is 2 GSa/s. To see the sample rate, press the Menu/Zoom key on the front panel. The sample rate is displayed in the line just above the softkeys.
5 Displaying Data Using Serial Decode Agilent’s hardware accelerated serial decode options can be licensed on 4-channel or 4+16-channel 5000 Series oscilloscopes. The following serial decode licenses are available: • The N5423A (Option LSS) license provides the ability to decode I2C (Inter-IC) and SPI (Serial Peripheral Interface) serial busses. • The N5424A (Option AMS) license provides the ability to decode CAN (Controller Area Network) and LIN (Local Interconnect Network) serial busses.

5 Displaying Data To reduce the random noise on a signal If the signal you are probing is noisy, you can set up the oscilloscope to reduce the noise on the displayed waveform. First, you stabilize the displayed waveform by removing the noise from the trigger path. Second, you reduce the noise on the displayed waveform. 1 Connect a signal to the oscilloscope and obtain a stable display.
Displaying Data 5 LF Reject Low-frequency reject (LF reject) adds a high-pass filter with the 3-dB point at 50 kHz.

By increasing the trigger hysteresis band, you reduce the possibility of triggering on noise.
5 Displaying Data To capture glitches or narrow pulses with peak detect and infinite persistence A glitch is a rapid change in the waveform that is usually narrow as compared to the waveform. Peak detect mode can be used to more easily view glitches or narrow pulses. In peak detect mode, narrow glitches and sharp edges are displayed more brightly than when in Normal acquire mode, making them easier to see.

Infinite persistence updates the display with new acquisitions but does not erase previous acquisitions.
Displaying Data 5 How AutoScale Works AutoScale automatically configures the oscilloscope to best display the input signals by analyzing any waveforms present at each channel and at the external trigger input. AutoScale finds, turns on, and scales any channel with a repetitive waveform that has a frequency of at least 50 Hz, a duty cycle greater than 0.5%, and an amplitude of at least 10 mV peak-to-peak. Any channels that do not meet these requirements are turned off.
5 Displaying Data Specifying the Channels Displayed After AutoScale The Channels softkey selection determines which channels will be displayed on subsequent AutoScales. • All Channels — The next time you press AutoScale, all channels that meet the requirements of AutoScale will be displayed. • Only Displayed Channels — The next time you press AutoScale, only the channels that are turned on will be examined for signal activity.

6 Saving and Printing Data Saving oscilloscope data Here are a few points about saving oscilloscope data: • You can save a waveform trace and recall it later. The recalled trace appears in cyan (blue). • You can save oscilloscope setup parameters and recall them later. The setup file stores settings such as horizontal timebase, vertical sensitivity, trigger mode, trigger level, measurements, cursors, and math functions.
Saving and Printing Data 6 Selecting a destination for your saved data Press Save/Recall→Save to access the Save menu and select a destination for saving your data. Press to go/Location/Save to softkey (Using the oscilloscope’s File Explorer) The second softkey from the left in the Save menu is the file explorer softkey. If no USB storage device is connected to the oscilloscope, you will only be able to save Trace and Setup files to the oscilloscope’s internal memory.
6 Saving and Printing Data If one or more USB storage devices are connected to the oscilloscope, you can navigate to the USB device using the same method. The following display image shows an image ready to be saved to a subfolder called “Rise time” on a USB device. Push the Entry knob to save the image. Selecting a file name Overwriting a file You can choose to overwrite an existing file name by browsing to that file and selecting it, then choosing Press to Save.
Saving and Printing Data 6 3 You can press the Enter softkey or the Entry knob to move the cursor forward within the file name. 4 You can press the Delete Character softkey to delete the current character and shift the rest of the characters to the left. 5 When you select the Auto Increment option, the oscilloscope will add a numeric suffix to your file name, and increment the number with each successive save.
6 Saving and Printing Data Waveform Trace and Oscilloscope Setup When the Trace & Setup option is selected from the Format softkey, both waveform trace and oscilloscope setup are saved to the USB drive or the oscilloscope’s internal memory. After saving, you can choose to recall the trace, the setup, or both. The trace is saved with the file extension TIF and the setup is saved with the extension SCP.
Saving and Printing Data 6 • ASCII XY data file - This creates a file of comma-separated variables for each displayed channel. If the oscilloscope acquisition is stopped, then data records greater than 1000 points can be written. This format is also suitable for spreadsheets. • BIN data file - This creates a binary file with a header, and data in the form of time and voltage pairs. This file is much smaller than the ASCII XY data file.
6 Saving and Printing Data The Invert Graticule Colors option can be used to reduce the amount of black ink it takes to print oscilloscope images by changing the black background to white. Invert Graticule Colors is the default mode. Invert Graticule Colors is available when the BMP and PNG formats are selected. Graticule Not Inverted Graticule Inverted Palette Press the Palette softkey to change the following options. The Palette options are available when the BMP and PNG formats are selected.
Saving and Printing Data 6 The Length control will perform a “1 of n” decimation of the data when necessary. For example: if the Length is set to 1000, and you are displaying a record that is 5000 data points in length, four of each five data points will be decimated, creating an output file 1000 data points in length. For more information see “Minimum and Maximum Values in CSV Files” on page 281. To save a waveform and/or setup to a USB device 1 Insert a USB drive into the front or rear USB device port.
6 Saving and Printing Data To recall waveform trace and/or oscilloscope setup A recalled trace is typically used for a quick comparison of measurement results. For example, you might save a trace of a waveform to use as a reference, then make a similar measurement on a test system and then recall the saved trace to observe any differences. 1 Press the Save/Recall key. 2 Press the Recall softkey. The Recall Menu will be displayed.
Saving and Printing Data 6 When the USB storage device is connected to the oscilloscope’s front or rear USB host port, a small four-color circle icon may be displayed briefly as the USB device is read. You do not need to “eject” the USB device before removing it. Simply ensure that any file operation you’ve initiated is done, and remove the USB drive from the oscilloscope’s host port.
6 Saving and Printing Data To use the file explorer Files can be loaded and deleted using the file explorer. You can create directories on a USB mass storage device using your PC or other instrument. You can navigate to any directory on the USB device by rotating the Entry knob and pressing the softkey. 1 Connect a USB mass storage device with the files to be loaded or deleted to the USB port on the front or the rear of the oscilloscope.
Saving and Printing Data 6 Secure Environment Mode Option Secure environment mode is compliant to National Industrial Security Program Operating Manual (NISPOM) Chapter 8 requirements. When you order your oscilloscope with the secure environment mode option, trace and setup data are stored to internal volatile memory (rather than internal non-volatile memory). Oscilloscope setup, waveform, and trace data are erased when the power is shut off.

7 Reference Software and firmware updates From time to time Agilent Technologies releases software and firmware updates for its products. To search for firmware updates for your oscilloscope, point your web browser to www.agilent.com/find/dso5000 and select Technical Support, then select Software Downloads & Utilities. To view the currently installed software and firmware press Utility&Service&About Oscilloscope.
Reference 7 To set up the I/O port The oscilloscope can be controlled via GPIB, LAN, or USB. By default, all three are active, although they can be selected or disabled using the Control softkey in the I/O menu (press Utility&I/O). The oscilloscope’s I/O configuration, including its IP address and hostname, can be viewed by pressing Utility&I/O. To change the I/O controller settings, press the Configure softkey, and choose the I/O connection type (GPIB, LAN, or USB).
7 Reference To return the instrument Before shipping the oscilloscope to Agilent Technologies, contact your nearest Agilent Technologies sales or service office for additional details. Information on contacting Agilent Technologies can be found at www.agilent.com/find/contactus. 1 Write the following information on a tag and attach it to the oscilloscope.
Reference 7 Binary Data (.bin) The binary data format stores waveform data in binary format and provides data headers that describe that data. Because the data is in binary format, the size of the file is approximately 5 times smaller than the XYPairs format. If more than one source is on, you will save all displayed sources, except math functions, to a file.
7 Reference File Size A 32-bit integer that is the number of bytes that are in the file. Number of Waveforms A 32-bit integer that is the number of waveforms that are stored in the file. Waveform Header It is possible to store more than one waveform in the file, and each waveform stored will have a waveform header. The waveform header contains information about the type of waveform data that is stored following the waveform data header.
Reference 7 X Display Range A 32-bit float that is the X-axis duration of the waveform that is displayed. For time domain waveforms, it is the duration of time across the display. If the value is zero then no data has been acquired. X Display Origin A 64-bit double that is the X-axis value at the left edge of the display. For time domain waveforms, it is the time at the start of the display. This value is treated as a double precision 64-bit floating point number.
7 Reference Time A16-bit character array, left blank in the 5000 Series oscilloscope. Frame A 24 byte character array that is the model number and serial number of the oscilloscope in the format of: MODEL#:SERIAL#. Waveform Label A 16 byte character array that contains the label assigned to the waveform. Time Tags A 64-bit double, not used in the 5000 Series oscilloscope. Segment Index A 32-bit unsigned integer, not used in the 5000 Series oscilloscope.
Reference 7 Waveform Data Header A waveform may have more than one data set. Each waveform data set will have a waveform data header. The waveform data header consists of information about the waveform data set. This header is stored immediately before the data set. Waveform Data Header Size A 32-bit integer that is the size of the waveform data header. Buffer Type A 16-bit short that is the type of waveform data stored in the file: • 0 = Unknown data. • 1 = Normal 32-bit float data.
7 Reference Examples of Binary Files Single Acquisition Multiple Channels The following picture shows a binary file of a single acquisition with multiple oscilloscope channels.
Reference 7 Minimum and Maximum Values in CSV Files If you are running a Quick Measurement Minimum or Maximum measurement, the minimum and maximum values shown in the Quick Measurement display may not appear in the CSV file. Explanation: When the oscilloscope’s sample rate is 4 GSa/s, a sample will be taken every 250 ps. If the sweep speed is set to 100 ns/div, there will be 1000 ns of data displayed (because there are ten divisions across the screen).
