PMU pulse timing preview
Before executing an ITM test, you can preview a waveform generated using the settings. This can
help you understand the behaviors of the various test settings without applying signals to the test
device. The Pulse Timing Preview is in the PMU Advanced Test Settings dialog box. An example is
shown in the following figure.
Figure 53: Pulse Timing Preview example
The preview displays representations of the waveforms for the different PMU channels in the test.
The illustrated pulse waveforms are defined by the Pulse Timing settings for the specific PMU. This
graphical depiction provides a representation of parameter values (no signals are output to the test
device). It is not intended to be a strict definition of the actual number of pulses or pulse voltages that
will be applied to the device under test (DUT). When the actual test is running, the actual number of
pulses or pulse voltages may be different from the preview.
Enabling current measure ranging or load-line effect compensation (LLEC) requires additional pulses
to what is shown in the preview. To learn about how the PMU handles device under test (DUT) load
variation and measure ranging during a test, see
How LLEC adjusts pulse output to the target levels
(on page 2-22).
