Fig. 3.6: ZOOM function 3.4 Cursor Measurements After displaying and reviewing the signal, the next step will introduce cursor measurements of the signal. Again, briefly press the AUTOSET key once followed by the CURSOR/MEASURE key. You can now select the desired type of measurement cursor from the menu. Press the soft menu key MEASURE TYPE to open the appropriate selection menu.
Quick Start Guide 3.6 Mathematical functions In addition to cursor and automatic measurements, your R&S®HMO1002 can also apply mathematical operations to the signals. Pressing the MATH 26 key opens a menu enabling you to apply addition, subtraction, multiplication or division to two analog channels. This also displays the mathematical graph. The top soft menu key allows you to select the first operand. With the key below, you can select the operator.
Vertical System 4 Vertical System You can select vertical settings using knobs for the vertical position and the 22 sensitivity. You may also use 18 a menu that is permanently 23 displayed as well as an ad19 vanced menu. You can select 24 for which channel you want the settings to be activated 25 by pressing the respective 20 channel key. Once a channel 26 has been activated, the key 21 will be marked by a colored 27 LED light. Additionally, the screen display will include a Fig. 4.
Vertical System SETUP key in the GENERAL section, and then press the soft menu key PROBE COMP. This compensation wizard will guide you through all the important points of the probe compensation. After connecting a probe, you can select the respective analog channel via soft menu key CHANNEL 1 (CH1) or CHANNEL 2 (CH2). The enclosed HZ154 probe stylus allows you to set the probe trimmers to an optimal square wave shape. The compensation is performed at 1 kHz (LF) and 1 MHz (HF).
Horizontal System 5 Horizontal System D 37 38 37 41 42 39 43 40 44 Fig. 5.1: Control panel of the horizontal system In the HORIZONTAL system section, users can select time base settings for capturing, trigger time position, zoom functions, acquisition modes, marker functions and search functions. Knobs allow you to set time base and trigger time position. A menu enables you to select the desired acquisition mode. A separate key is available to activate the zoom.
Horizontal System During peak detection, the oscilloscope distinguishes between two types: ❙❙ Acquisition peak detection: Each A/D converter converts at the full sampling rate (no Interlace mode), even if results have not been written to the acquisition memory at full sampling rate (for slow time bases, for instance). If peak detection is activated, unused converter values will be evaluated to detect minimum and maximum amplitudes.
Horizontal System window displays up to 40 detected data values (limited by processor performance). How much data is currently displayed depends on the displayed time window and the current sampling rate. If peak detection is activated, each The entire oscilloscope memory can only be read out in STOP mode if the maximum sampling rate has been activated. memory).
Horizontal System also possible to zoom out at the maximum repeat rate if the STOP mode was run at fast time bases. If a high repeat rate can only be attained by means of low memory depth (as is the case with other manufacturers) it is nearly impossible to zoom in retrospectively in STOP mode. 5.4 Interlace Mode In interlace mode, ADC and storage of two channels are connected. This doubles the sampling rate and the acquisition memory.
Horizontal System position and setting it to the center of the screen using the position knob, you can set an additional marker. This procedure allows you to mark up to 8 interesting positions within the signal. You can toggle between markers by 37 . These keys also allow you pressing the arrow keys to center the markers in the middle of the screen. This feature enables you to quickly compare marked signal sections in ZOOM mode.
Trigger System 6.3 Trigger type The trigger type can be selected with the TYPE key 17 in the TRIGGER section. A submenu will be opened. 6.3.1 Edge Trigger The easiest and by far the most frequently used trigger is the edge trigger. The oscilloscope triggers if slopes that were set with the EDGE key occur within the signal selected in the SOURCE menu. The signal slope has to pass through the set trigger level. The trigger type EDGE TRIGGER is selected in the Autosetup mode (AUTOSET key).
Trigger System MENU section. Selecting the corresponding soft menu item allows you to set any of these settings for positively (POS.) or negatively polarized pulses (NEG.). For the associated positive pulse, you define the width from rising to falling slopes, and accordingly for the associated negative pulse from falling to rising slopes. As is consistent with the principle, triggering always occurs on the second slope of the pulse. 6.3.
Trigger System 6.3.4 Video Trigger The video trigger allows you to trigger on PAL, NTSC SECAM standard video signals or on HDTV signals. After selecting the VIDEO trigger press the SOURCE 32 key. The FILTER 36 menu allows you to define additional settings. The oscilloscope triggers if the CVBS signal (Color Video Baseband Signal) selected in the SOURCE menu features the attributes set in the FILTER menu. Select the desired standard by pressing the respective soft menu key STANDARD.
Signal Display 7 Signal Display The following chapter describes the selection and display of signals from various sources as well as all available display modes. 7.1 Display Settings The R&S®HMO1002 features a high quality TFT display with VGA (640x480 pixels resolution) including LED backlighting. Basic display settings can be defined by pressing the DISPLAY 14 key in the GENERAL section. When the soft menu item VIRTUAL SCREEN is activated, a scroll bar will display to the right of the display graticule.
Signal Display 7.3 Signal Intensity Display and Persistence Function The default setting (indicated as active when the INTENS/ PERSIST 7 key is illuminated in white) allows you to use the universal knob to change the intensity of the signal display to anywhere from 0% to 100%. Persistence mode allows the display of varying signals by enabling the instrument to write several signals on the display simultaneously.
Signal Display 8 Measurements There are two different types of measurements on signals: cursor measurements and automatic measurements. All measurements are stored in a buffer memory that is larger than the display memory. The integrated hardware counter shows the frequency and period duration for the selected input. 8.1 Cursor Measurements The measurement option that is most frequently used with an oscilloscope is the cursor measurement. Depending on the measurement type up to three markers are available.
Measurements tes without voltage reference are displayed here. If “?” is displayed, the display does not show a complete measurement result. For instance, the period to be measured may not display completely and can consequently not be identified. PEAK + : This mode measures the maximum voltage value in the displayed view of the screen. The measurement will only be applied to the selected channel (Vp+). If the function AUTOM.
Measurements slope. This measurement type identifies the two slopes and calculates the pulse width from their time difference. The measurement will only be applied to the selected channel and requires a minimum of one completely displayed period of a triggered signal. . PULSE WIDTH –: This mode measures the width of the negative pulse. A negative pulse consists of a falling slope followed by a rising slope.
Analysis calculated from the amplitude of the measurement signal. A slope will be counted if the signal runs through the mean value. The measurement will only be applied to the selected channel. COUNT –/ : This mode counts signal changes (slopes) from High Level to Low Level in the displayed view of the screen. The mean value is calculated from the amplitude of the measurement signal. A slope will be counted if the signal runs through the mean value.
Analysis 9.2 Frequency Analysis (FFT) In general, the FFT in an oscilloscope works differently than in a spectrum analyzer and is affected not only by the time base setting, but also by the available number of used acquired data points when calculating the FFT. The R&S®HMO1002 allows you to include up to 128k point in the FFT. The FFT is not suitable for the analysis of very slow signals (Hzrange); this type of analysis requires a classic oscilloscope mode.
Analysis ased noise. This function can be used for pulse response tests with start and end values of zero. The menu item Y-SCALING allows you to scale the FFT in the amplitude logarithmically (dBm / dBV) or linear (Veff). The unit dBm (Decibel-Milliwatt) refers to 1 mW. The unit dBV (Decibel-Volt) refers to 1 Veff. The displayed values refer to a 50 Ohm terminating resistor. You can use an external terminating resistor parallel to the high impedance input.
Analysis ❙❙ Screen dump for first-time failure on USB stick ❙❙ Screen dump for first-time failure on printer An action is performed if the respective condition is met (e.g. a specific number of mask failures). Each action is assigned a unique condition which can be defined separately from the other actions. The respective condition can be defined in the menu for the corresponding action.
Analysis pected which will point to the defective component. Rather exact results may be achieved if the measurements are compared to those of intact components. This is especially true for semiconductors. The polarity of diodes or transistors can thus be identified if the lettering or marking is missing. Please note that with semiconductors changing the polarity will cause the display to rotate 180 degrees around the screen center.
Signal Generation 10 Signal Generation 10.1 Function Generator The R&S®HMO1002 includes an integrated function generator which can generate input signals while testing circuits, for instance. To activate the function generator, select the UTIL menu in the VERTICAL control panel, and then press the soft menu key FUNCTION GEN. The following waveforms can be generated and made available at the AUX OUT connector: ❙❙ DC ❙❙ SINE: Frequency range from 0.1 Hz to 50 kHz ❙❙ SQUARE WAVE: Frequency range from 0.
