Taking automatic measurements in the time domain
This topic explains how to take an automatic measurement in the time domain.
To take an automatic measurement in the time domain:
1. If the instrument is in the frequency domain, tap the 2 button or push the channel 1 front panel button.
2. Tap Measure to display the Add Measurements menu.
3. Tap a measurement category panel to display available measurements.
4. Tap Source and select the desired source for the measurement.
5. Tap the desired measurement.
6. Tap Add to create the measurement results badge.
7. To remove a measurement, tap the measurement results badge and flick it off the display.
Quick Tips
• A symbol and Clipping appears if a vertical clipping condition exists. Part of the waveform is above or below the display. To obtain a
proper numerical measurement, turn the vertical scale and position knobs to make all of the waveform appear in the display.
• If the oscilloscope displays an error message, change the instrument setup, such as increasing the record length of the acquisition or
changing the horizontal scale so that the instrument has more points or edges from which to calculate the measurement.
Taking automatic measurements in the frequency domain
This topic explains how to take an automatic measurement in the frequency domain.
To take an automatic measurement in the frequency domain:
1. If the instrument is in the time domain, tap the RF button or push RF front-panel button.
2. Tap Measure to display the Add Measurements menu.
3. Tap the measurement of interest from the menu. As you select each frequency measurement, on screen help will appear to explain the
purpose of that measurement.
• Channel Power: The total power within the bandwidth, defined by the Channel Width.
• Adjacent Channel Power Ratio: The power in the main channel and the ratio of channel power to main power, for the upper and
lower halves of each adjacent channel.
• Occupied Bandwidth: The bandwidth that contains the specified % of power within the analysis bandwidth.
4. Tap Add to create the measurement results badge.
5. To configure the measurement, double-tap the measurement badge.
6. After you set the measurement parameters in the resulting menu, the instrument will automatically set the span. When the RF
measurements are on, the Auto detection method will set all frequency domain traces to the Average detection method. This provides
optimal measurement accuracy.
Taking digital voltmeter measurements
Use the digital voltmeter to measure the potential difference between two points in an electrical circuit.
Use this procedure to take digital voltmeter measurements.
1. Tap the DVM button to display the DVM results badge.
2. Double-tap the DVM results badge to display the DVM menu.
3. Tap the Display field to toggle the digital voltmeter on and off.
4. Tap the Source field and select the source from the drop-down list. Measurements will be taken on this source.
