3: Setting up PMUs and PGUs in Clarius Model 4200A-SCS Pulse Card (PGU and PMU)
3-30 4200A-PMU-900-01 Rev. B March 2023
If you change the number of pulses to three (instead of one) and only display one channel (PMU1-1,
instead of Show All), the preview of the waveform changes as shown in the following figure. Each
point in the step now uses three periods, so there are three pulses shown in the Expanded View. In
the Expanded View, the x-axis shows the time in seconds. This is three times longer than the
Expanded View graph when number of pulses is set to one that was shown in the previous figure.
Figure 59: Two-channel test (stepping and sweeping) with three points (only PMU1-1
displayed)
If you configure the preview to all channels, both the sweeper and stepper are displayed for the
three-pulse test, as shown in the following figure.
The Number of Pulses parameter determines the number of pulses that are output and measured for
each attempted point in the sweep or step. The PMU amplitude sweep and step example
(two-channel) test figure shows PMU1-1 (the stepper) with the number of pulses changed to three.
Notice that each sweep point of the displayed waveform in the figure has three pulses (number of
pulses set to three). The light blue waveform in the figure has one pulse (number of pulses set to one).
Because the cursor in the lower graph always contains the complete waveform of each point in a test,
the top graph shows the three pulses. The following figure shows both channels for the sweep and
