Pmu Amplitude Sweep And Step Example (Two-Channel) - Keithley 4200A-SCS User Manual

Model 4200A-SCS Pulse Card (PGU and PMU) User's Manual
Select Preview Test to animate the waveform. The cursor moves from left to right on the bottom
graph while displaying the point waveform of each sweep within the cursor on the top graph.
Selecting Preview Test does not output any pulses; it just illustrates how the test will progress as a
result of the test parameter settings.

PMU amplitude sweep and step example (two-channel)

In this two-channel example, one channel is sweeping while the other channel is stepping. The
sweeping channel is performing pulse amplitude sweeps with nine sweep points. On each inner loop,
PMU1-2 sweeps 0 V through 4 V in 0.5 V increments. The stepping channel is performing pulse
amplitude steps with four step points. On the outer loop, PMU1-1 pulses the four steps of 1 V through
2.5 V in 0.5 V increments.

To preview the test, select the Test Settings tab, then select Advanced. You can preview a single
channel or all channels in the test. The graph of the entire test (the lower graph of following figure)
shows four steps of nine points each. The sweep and step count displays the position of the cursor in
the overall test. This example has the number of pulses set to one.
