Operating requirements Operating requirements Make sure to operate the instrument within the following environmental and power requirements.
Getting acquainted with the oscilloscope Getting acquainted with the oscilloscope This section shows you how to power on the oscilloscope, and uses a hands-on approach to introduce you to key oscilloscope functions, using the menu system, and verifying that the oscilloscope is operating correctly.
Getting acquainted with the oscilloscope Powering on and off the oscilloscope Grounding the oscilloscope is necessary for safety and to take accurate measurements. The oscilloscope must share the same ground as any circuits that you are testing. You connect the oscilloscope to ground by plugging the three-pronged power cord into an outlet grounded to earth ground.
Getting acquainted with the oscilloscope NOTE. The current instrument settings are stored in nonvolatile memory when you power off the oscilloscope. The oscilloscope restores the settings when you power on. Changing the user interface language You can change the language used for the oscilloscope on-screen display, measurements, readouts, and menus to one of 11 languages. The following steps show how to change the user interface language. These steps also introduce you to the oscilloscope menu system. 1.
Getting acquainted with the oscilloscope The oscilloscope opens the Language menu. You will use the Multipurpose knob to select and click menu items. The following text describes how the Multipurpose knob works. The Multipurpose knob lets you interact with on-screen menus, messages, and dialog boxes. A blue-colored M icon on a menu, message, or dialog box label means that you can use the Multipurpose knob to select and click values in that item.
Getting acquainted with the oscilloscope 4. Click (push) the Multipurpose knob to enter the highlighted language. The selected language takes effect immediately. 5. Push the Menu On/Off button to close the Utility menu. 6. If you load a language other than English, install the plastic overlay on the front panel to provide labels in that language. Fold the overlay tabs. Push the overlay over the knobs until the knob hole tabs click over the bottom edges of the knobs.
Getting acquainted with the oscilloscope Changing the date and time Set the current data and time so that files that you save are marked with the correct date and time. The date and time are shown in the lower-right corner of the screen. Time is shown using a 24-hour clock. NOTE. The clock does not automatically adjust for seasonal time changes. The calendar does adjust for leap years. The following steps show how to set the oscilloscope clock with the current date and time.
Getting acquainted with the oscilloscope 4. Click the Multipurpose knob to enable setting the year value. A white box is drawn around the number field, indicating that you can use the Multipurpose knob to change that value. 5. Turn the Multipurpose knob to change the year value in the field. When the value is correct, click the Multipurpose knob. This enters the number and returns the knob to menu select mode. 6.
Getting acquainted with the oscilloscope Connecting probes to the oscilloscope You must connect probes or cables to an oscilloscope before you can display a waveform and take measurements. The following text describes how to connect probes to the oscilloscope. 1. BNC probes or cables: Push the BNC probe or cable on to the connector so that the connector pins align with the slots, then turn the BNC connector clockwise to lock. The probes that ship with the oscilloscope are BNC connector probes. NOTE.
Getting acquainted with the oscilloscope Doing a functional check Perform this quick functional check to verify that your oscilloscope is operating correctly. 1. Connect the oscilloscope power cable as described in Powering On the Oscilloscope. (See page 7.) 2. Power on the oscilloscope. 3. Connect a probe that came with the oscilloscope to channel 1. 4. Connect the probe tip and ground lead to the PROBE COMP connectors on the oscilloscope front panel.
Getting acquainted with the oscilloscope 6. Push Autoset. The screen displays a square wave. If the displayed square wave tops are not flat, perform the procedures to compensate the probe high frequency response. You can compensate the probe after completing this functional check. (See page 17.) 7. Push Measure to open the Measurement Selection menu.
Getting acquainted with the oscilloscope 8. Turn the Multipurpose knob to select Snapshot. 9. Click the Multipurpose knob to show the Snapshot screen.(See page 51, Taking a measurements snapshot.) Verify that the Frequency value is ~1 kHz and the Period value is ~1 ms, respectively. 10. Push the Menu On/Off button to close the Snapshot screen. Push the Menu On/Off button again to close the Measurement screen. What is Autoset? The functional check used the Autoset button to display a stable waveform.
Getting acquainted with the oscilloscope Compensating a passive voltage probe Probe compensation adjusts a passive (nonamplified) voltage probe for the most accurate high-frequency response. The oscilloscope has a 1 kHz square wave source for compensating the probe. Because a square wave contains a significant number of harmonics (multiples of the fundamental frequency), it is an ideal signal source for adjusting the high frequency response of a probe.
Getting acquainted with the oscilloscope 4. Push Default Setup. 5. Push the Vertical Menu button for the channel to which the probe is connected, to display that channel. 6. Push Autoset. The screen displays a square wave.
Getting acquainted with the oscilloscope 7. Check the shape of the displayed waveform to determine if the probe needs adjusted. If the waveform has a square leading edge and a flat top and bottom, the probe does not need adjusted. If the waveform leading edge is rounded or has a spike, you need to adjust the probe compensation. 8. Use the probe adjustment tool to adjust the probe to show a flat top and bottom to the waveform. Remove the adjustment tool before looking at the waveform.
Getting acquainted with the oscilloscope Signal path compensation (SPC) Signal Path Compensation (SPC) corrects for DC level inaccuracies in the internal signal path caused by temperature variations and/or long-term signal path drift. You should run the SPC whenever the ambient (room) temperature has changed by more than 10 °C, or once a week if you use vertical scale settings of 5 mV per division or less.
Getting acquainted with the oscilloscope Getting on-screen help for settings: Help Everywhere Help Everywhere is a mode that displays graphics and short text descriptions when you access the menus for most oscilloscope settings. This is very useful for when you are first learning the functions of oscilloscope controls.

You can view any topic in any order. 1. Push the Function front-panel button. 2. Push the Scope Intro side-menu button. 3. Use the Multipurpose knob to select and click a topic heading. 4. Use the Multipurpose knob to select and click a topic to read. 5.
Sampling oscilloscope concepts Sampling oscilloscope concepts Read this section if you are a new oscilloscope user, or are new to using a digital oscilloscope. Sampling and acquisition concepts Before the oscilloscope can display or measure a signal, it must be sampled.
Sampling oscilloscope concepts Acquisition mode concepts The acquisition mode sets how the oscilloscope uses the sampled data points in each acquisition interval to create and display a waveform. You can set the acquisition mode to one of the following modes. Sample mode retains and uses the first sampled point from each acquisition interval to create the displayed waveform. This is the default mode.
Sampling oscilloscope concepts Trigger concepts The oscilloscope uses the data in the waveform record to construct and display a waveform on the oscilloscope screen. However, as the oscilloscope is constantly acquiring samples into the waveform record, each waveform record starts at a random point of the input signal. This means that the waveform record sample values are constantly changing, which results in a displayed waveform that is unstable or jittering.
Sampling oscilloscope concepts Pretrigger data can help you troubleshoot signal problems. For example, to find the cause of an unwanted glitch in your test circuit, trigger on the glitch signal and look at the pretrigger waveform. By analyzing what happens before the glitch, you may uncover information that helps you find the source of the glitch. Trigger slope and level concepts The oscilloscope must detect both the slope and level conditions before it can trigger and display a stable waveform.
Sampling oscilloscope concepts Trigger type Trigger conditions Edge Edge triggers are the simplest and most commonly used trigger type. An edge trigger event occurs when the trigger source passes through a specified voltage threshold (trigger level) when the signal is transitioning in the specified slope (rising or falling). You can trigger on a rising or falling edge, as defined by the slope control.
Sampling oscilloscope concepts Auto mode, when forcing triggers in the absence of valid triggering events, does not synchronize the waveform on the display. The waveform will appear to roll across the screen. If valid triggers occur, the display will become stable. Normal trigger mode. Normal mode sets the oscilloscope to acquire a waveform only when a trigger condition occurs. If no trigger occurs, the last waveform record acquired remains on the display.
Setting channel input parameters Setting channel input parameters Use the vertical Menu buttons to select waveforms to display or open menus and submenus with which to set input parameters for each channel. Each channel’s settings are independent of every other channel. Setting input signal coupling Input signal coupling sets how the input signal is passed to the oscilloscope sampling circuit. 1. Push the Vertical Menu button for the channel input that you want to set. 2.
Setting channel input parameters Setting the oscilloscope bandwidth Use this procedure to set the oscilloscope bandwidth. Bandwidth is the maximum frequency that an oscilloscope can accurately display and measure. The oscilloscope gradually attenuates (reduces) the signal level of frequencies that are higher than the bandwidth. This means that although you can display signals that are above the bandwidth limit, their amplitude values and other characteristics are not guaranteed to be accurate. 1.
Setting channel input parameters Setting the probe attenuation factor Attenuation is the amount that the probe reduces or amplifies the input signal amplitude before sending it to the oscilloscope input. The Attenuation submenu sets the probe attenuation factor for probes that do not have the TekProbe II or TekVPI interface. The default attenuation is 10x. 1. Push the Vertical Menu button for the channel input that you want to set. 2. Push the Probe Setup side menu to display the Probe Setup submenu. 3.
Setting channel input parameters 3. Use the Multipurpose knob to highlight the Measure Current submenu item. 4. Push the Multipurpose knob to toggle between Yes and No. 5. If you select Yes, the area below the Measure Current submenu displays the Amps/Volts or Volts/Amps ratio menu item. Use the Multipurpose knob to select and change the current measurement parameter.
Setting channel input parameters 5. To set the position to 0 (center graticule), use the Multipurpose knob to select and click Set to 0. The difference between vertical position and vertical offset Vertical position is a display function that moves the waveform image on the screen. Moving the signal on the screen does not change the ground (0 volt) baseline level for that signal. Vertical offset is a signal function that adds a DC voltage to the input signal before the oscilloscope preamplifier.
Setting channel input parameters 5. To set the deskew to the oscilloscope default (0 delay), use the Multipurpose knob to select and click Set to Default. Deskew tips Deskew settings are stored in nonvolatile memory until changed manually for each channel. Deskew settings are included in saved setup files. Doing a Default Setup resets deskew values to 0 on all channels.
Trigger setup Trigger setup Use these procedures to set up the oscilloscope to trigger on a signal. (See page 26, Trigger concepts.) Triggering on a waveform edge Use this procedure to set the oscilloscope to trigger on the rising or falling edge of a waveform. 1. Push the Trigger Menu front-panel button. 2. Push the Type side-menu button. 3. Use the Multipurpose knob to select and click Edge. 4.
Trigger setup Triggering on a specified pulse width Use this procedure to set the oscilloscope to trigger on a specified signal pulse condition. You can trigger when a pulse is less than, greater than, equal to, or not equal to a set time period (width). The minimum pulse width setting is 1 ns. (See page 27, Available trigger types.) Pulse width triggering is most often used to troubleshoot or analyze digital signals. 1. Push the Trigger Menu front-panel button. 2. Push the Type side-menu button. 3.
Trigger setup Triggering on a runt pulse Use this procedure to set the oscilloscope to trigger when a runt pulse occurs. You can also trigger when a runt pulse is less than, greater than, equal to, or not equal to a set time period (width). A runt pulse is a pulse that crosses one threshold level but fails to cross a second threshold before recrossing the first.
Trigger setup Setting the trigger mode Use this procedure to set the oscilloscope trigger Mode. The trigger mode sets how the oscilloscope behaves in the absence or presence of a trigger. Trigger mode also enables the trigger holdoff function. (See page 28, Trigger modes.) Trigger mode does not set the trigger conditions; those are set with the Trigger Type side-menu buttons. 1. Push the Trigger Menu front-panel button. 2. Push the Mode side-menu button. 3.
Acquisition setup Acquisition setup This section describes procedures for setting the oscilloscope acquisition parameters. Using Autoset Autoset is a fast way to acquire and display a waveform. Autoset automatically sets the trigger type to edge, sets the threshold level to 50% of the signal level, and analyzes the input signal and adjusts the oscilloscope acquisition, horizontal, and vertical settings to display five to six waveform cycles.
Acquisition setup 1. Push Utility. 2. Push -More- Page 1/2 side-menu button. 3. Push Autoset Enable side-menu button. 4. Use the Multipurpose knob to select and click Autoset Enable. The oscilloscope opens the Autoset Enable password entry screen. 5. Use the Multipurpose knob and side-menu buttons to enter the password that lets you disable Autoset. The factory default password is 000000 6. Push OK side-menu button to enter the password and let you disable Autoset.
Acquisition setup Starting and stopping an acquisition After you have defined the acquisition and trigger parameters, start acquiring and displaying a waveform with the Run/Stop or Single controls. Push Run/Stop to start acquisitions (button turns green). The oscilloscope acquires repeatedly until you push the button again to stop the acquisition, or push the Single button. Push Single to take a single acquisition. Single sets the trigger mode to Normal for the single acquisition.
Acquisition setup Setting the acquisition trigger delay time 1. Push Acquire. 2. Push the Delay side-menu button to toggle between On and Off. When set to Off, the expansion point is tied to the trigger point so that horizontal scale changes are centered around the trigger point. 3. With Delay set to On, the trigger point is disconnected from the expansion point. Turn the Horizontal Position knob to move the trigger point away from the expansion point (center graticule).
Acquisition setup 5. Push the Set Horizontal Position to 0s side-menu button to return the trigger point to the center of the waveform record (setting delay to 0). Pushing this button does not turn off the delay mode. You can also push the front-panel Horizontal Position knob to return the trigger point to the center of the waveform record. Trigger Delay is different than Trigger Holdoff. (See page 29, Holdoff trigger mode.) Setting the record length Use this procedure to set the record length.
Acquisition setup Maximum Zoomed waveform record captured with 2 million points Using the roll display mode Roll mode gives a display similar to a strip chart recorder, in that the waveform moves slowly, or rolls, from right to left on the screen. Roll mode is used to display low-frequency signals. Roll mode lets you see acquired data points without waiting for the acquisition of a complete waveform record.
Acquisition setup Setting the oscilloscope to factory default values (Default Setup) Default Setup clears the current oscilloscope settings and loads factory-defined settings. This lets you quickly reset the oscilloscope to a known state before setting up to take a new measurement. (See page 112, The default oscilloscope settings (Default Setup).) To return the oscilloscope to its factory default settings: 1. Push Default Setup. 2.
Waveform display settings Waveform display settings This section contains concepts and procedures for displaying and removing a waveform. Displaying and removing a waveform Use this procedure to turn on or off the display of each channel’s waveform. 1. To add or remove a waveform from the display, push the corresponding front-panel channel Menu button. If the selected channel is already active, pushing the channel Menu button removes the waveform.
Waveform display settings 4. Use the Multipurpose knob to change and set the Persist Time value. The range is Auto (which is the same as 0 s), 0 s 10 s (in one second increments), and infinity. 5. To clear the persistence of the displayed waveform, select and click Clear Persistence. This does not change the persistence setting, but just clears the displayed waveform persistence data.
Waveform display settings 2. Push Acquire. 3. Push XY Display side-menu button to toggle XY display mode On and Off. XY display mode tips Because the XY display is simply a different way of displaying pairs of waveforms, the underlying waveforms are available for measurements, and for saving to reference memory or a USB drive for off-line analysis. Use a Web browser and search on the keyword “lissajou patterns” to find more information on XY plots.
Analyzing a waveform Analyzing a waveform After having properly set up the acquisition, triggering, and display of your waveform, you can then analyze the results. Select from features such as displaying automatic measurements, using cursors to measure specific parts of a waveform, using math to perform an operation on two waveforms, and using FFT to display the frequency components of a signal. You can also use Gating to analyze only a specified part of a waveform when you take measurements.
Analyzing a waveform Automatic measurements tip A symbol appears next to a measurement if a vertical signal clipping condition exists. Part of the waveform is above or below the upper or lower edge of the screen. Signal clipping causes inaccurate measurements. To obtain an accurate measurement, turn the Vertical Scale and Position knobs so that all of the waveform is on the screen.
Analyzing a waveform Automatic measurement descriptions The following tables list the automatic measurements, grouped as shown on the measurements menu. Measurement descriptions can also be shown on the oscilloscope by enabling Help Everywhere (Function > Help Everywhere). (See page 21, Getting on-screen help for settings: Help Everywhere.) Frequency measurement descriptions Frequency measurements Measurement Description Frequency The first cycle in a waveform or gated region.
Analyzing a waveform Time measurements (cont.) Measurement Description Fall Time The time required for the falling edge of the first pulse in the waveform or gated region to fall from the high reference value to the low reference value of the final value. DelayRR The time between the mid reference (default 50%) amplitude point of the rising edge of two different waveforms. See also Phase. This measurement requires inputs from two channels.
Analyzing a waveform Amplitude measurements 54 Measurement Description Peak-to-peak The absolute difference between the maximum and minimum amplitude in the entire waveform or gated region. Amplitude The average high value less the average low value measured over the entire waveform or gated region. Max The most positive peak voltage. Max is measured over the entire waveform or gated region. Min The most negative peak voltage. Min is measured over the entire waveform or gated region.
Analyzing a waveform Area measurement descriptions Area measurements Measurement Description Area A voltage over time measurement. The measurement returns the area over the entire waveform or gated region in volt-seconds. Area measured above ground is positive; area measured below ground is negative. Cycle Area A voltage over time measurement. The measurement is the area over the first cycle in the waveform or the first cycle in the gated region expressed in volt-seconds.
Analyzing a waveform Using cursors to take manual measurements Cursors are on-screen vertical and horizontal lines that you position on a waveform to take measurements. The cursors have readouts that show the value at their position or where they cross a waveform. Cursors also show the absolute difference measurement value (or delta) between two cursor positions. Cursor readouts appear next to the cursors. The readouts show the signal values at the current cursor positions.
Analyzing a waveform 3. Push the Multipurpose knob to select the other cursor (which becomes a solid line), then turn the knob to move that cursor. The first cursor is now drawn with a dotted line. 4. To make smaller cursor position adjustments, push the Fine button to toggle between making coarse and fine cursor position adjustments.
Analyzing a waveform Screen cursors: A combination of both the vertical and horizontal cursors. Click the Multipurpose knob to cycle through selecting the cursors. NOTE. The vertical cursors in screen mode are not tied to where the cursor crosses the waveform, and so do not show the amplitude value where they cross the signal. Amplitude values are read from the horizontal cursors.
Analyzing a waveform An example of using a math waveform is to calculate instantaneous power (current times voltage) by multiplying a voltage waveform and a current waveform. Math waveform tips Math waveforms get their horizontal scale and position from the sources channels. Adjusting these controls for the source waveforms also adjusts the math waveform. Adding or subtracting waveforms with different units sets the math waveform units to “?”.
Analyzing a waveform The oscilloscope shows the default FFT screen. The lower main screen shows the FFT waveform. Use the Vertical Position knob of the source channel to move the FFT waveform up or down. 3. Push Source wfm side-menu button to toggle the display of the source waveform (at the top of the screen) On or Off. 4. Push the Source side-menu button and use Multipurpose knob to set the source to channel 1, 2, 3, or 4.
Analyzing a waveform 8. Push the Horizontal Scale side-menu button and use the Multipurpose knob to set the horizontal scale (frequency per major graticule division) value. Use this to expand or contract the FFT waveform to show more or less detail. The FFT waveform expands around the center cursor. 9. Push the Cursors front-panel button and use the cursors to take measurements. FFT tips You can only display FFT waveforms for 2000 and 20K record length waveforms.
Analyzing a waveform About FFT windows The FFT algorithm applies a ‘window’ process to the source waveform record to ‘shape’ the record so that the start and stop values for the FFT waveform are close to the same amplitude. Starting and stopping the waveform at close to the same amplitude reduces adding artificial waveform that are not present in the actual signal. Using a window on the source signal results in an FFT waveform that more accurately represents the source signal frequency components.
Analyzing a waveform Table 2: FFT windows (cont.) Window type Window ‘shape’ Hamming This is a very good window for resolving frequencies that are very close to the same value with somewhat improved amplitude accuracy over the rectangular window. It has a slightly better frequency resolution than the Hanning. Use Hamming for measuring sine, periodic, and narrow band random noise. This window works on transients or bursts where the signal levels before and after the event are significantly different.
Analyzing a waveform Displaying reference waveforms A reference waveform is a waveform that you have stored in a nonvolatile memory location on the oscilloscope. You can use a reference waveform as a standard against which to compare other waveforms. You can save channel, math, and FFT waveforms to reference memory. Reference waveforms remain in memory when the oscilloscope is powered off. See the Saving waveform data topic to learn how to save waveforms to reference memory or external files.
Analyzing a waveform How to view long record length waveforms (Zoom) The Navigation controls (Zoom button, the Zoom side menu, and the Multipurpose knob) let you magnify and examine portions of a waveform (Ch1-Ch4, Math, Reference). A zoomed display consists of two parts. The upper display shows the entire displayed waveform record and the position and size of the zoomed part in the waveform (in brackets) within the entire record.
Saving data Saving data The oscilloscope has internal memory locations where you can save instrument setups and waveforms. You can also save screen images, setups, and waveforms to files on an external USB drives. Saving screen images to a file Use this procedure to save a screen image to a file on a USB drive. A screen image is a ‘picture’ of the oscilloscope screen. Screen images are useful to include in reports or to compare with other screen images over time. NOTE.
Saving data BMP: This bitmap format uses a lossless algorithm, and is compatible with most word processing and spreadsheet programs; this is the default. Creates the largest file size. JPG: This bitmap format uses a lossy compression algorithm, and is compatible with most word processing and spreadsheet programs. Creates the smallest file size. PNG: This bitmap format uses a lossless compression algorithm, and is compatible with most word processing and spreadsheet programs.
Saving data NOTE. The selected waveform must be displayed on the screen to save waveform data. e. Push the To side-menu button. f. Select and click Ref1 or Ref2. g. Push the Save side-menu button. 7. To save waveform data to a file on the USB drive: a. Push the Save To side-menu button. b. Select and click USB File (*.ISF) or USB File (*.CSV). (See page 68, About waveform data files.) c. Push the Source side-menu button d. Select and click the waveform data source (CH1-CH4, Math, FFT, Ref1, Ref2). NOTE.
Saving data Saving oscilloscope setup information You can save the oscilloscope internal settings to an internal memory location (setup 1–10) or to an external file on the USB drive. A setup file contains most of the oscilloscope settings, including vertical, horizontal, trigger, cursor, and measurement parameters. It does not include communications information, such as GPIB addresses. You can then use the setup data to quickly set the oscilloscope to take a certain measurement.
Saving data Saving files to USB with the Save File button The Save File button is a quick, one-push way to save a specified data files to the USB drive. After you have defined the save parameters with the Save/Recall button and Action side-menu button, you can assign that save action to the Save File button. For example, if you assign Save to write waveform data to a USB drive, then each push of the Save button saves the current waveform data to the USB drive. NOTE.
Recalling data Recalling data The oscilloscope provides permanent internal memory locations from which you can recall instrument setups and waveforms. You can also recall (load) setups and waveforms from files on an external USB drive.
