3: Setting up PMUs and PGUs in Clarius Model 4200A-SCS Pulse Card (PGU and PMU)
3-16 4200A-PMU-900-01 Rev. B March 2023
Threshold Voltage
The voltage threshold allows you to set a voltage threshold. If the threshold is reached or exceeded,
the present sweep is stopped. Testing continues with any subsequent sweeps.
This threshold is a comparison of the measurement after the pulse has been applied to the DUT (the
threshold value will be exceeded, at least slightly). The degree to which the signal exceeds the
threshold before the threshold is triggered is a function of the DUT response and test configuration.
Generally, smaller voltage step sizes will reduce the amount that the signal exceeds the threshold.
You can specify more than one threshold for each channel.
Threshold Power
The power threshold allows you to set a power threshold. If the threshold is reached or exceeded, the
present sweep is stopped. Testing continues with any subsequent sweeps.
This threshold is a comparison of the measurement after the pulse has been applied to the DUT (the
threshold value will be exceeded, at least slightly). The degree to which the signal exceeds the
threshold before the threshold is triggered is a function of the DUT response and test configuration.
Generally, smaller voltage step sizes will reduce the amount that the signal exceeds the threshold.
You can specify more than one threshold for each channel.
On the 40 V range, you may see the error message, "Pulse waveform configuration exceeded output
power limits." To solve this issue, try increasing the period or using the 10 V range.
PMU Test Settings
The settings that are available for PMU tests are described in the following topics.
Pulse Settings
Under Pulse Settings, you can select the type of pulse test, how measured pulse values are handled,
and the number of pulses.
Test Mode (PMU)
The Test Mode selects the type of pulse test. You can select:
• Pulse IV: This test mode performs spot mean measurements (V or I) of the amplitude or base
portions of one or more pulses. Typically, current versus voltage is graphed in the Analyze graph.
The pmu-iv-sweep project provides an example of a pulse drain family of curves using the
pulse test mode.
• Waveform Capture: This test mode samples the entire waveform. The waveform is graphed
(voltage and/or current versus time) in the Analyze graph. The pmu-1ch-wfm project provides an
example of a waveform capture. Note that the Timing Sweep Step option (in the Advanced dialog)
is disabled when Waveform Capture is selected.
