5: Pulse measure and pulse generator units Model 4200A-SCS Parameter Analyzer
5-26 4200A-901-01 Rev. C / February 2017
Configuring the preview to all channels displays both the sweeper and stepper for the three-pulse test
(see next 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 next figure shows both channels for the sweep and step test with
the number of pulses set to three. Note that the value for the number of pulses does not affect the
number of sweep or step points in the test.
