Section 5: Pulse measure and pulse generator units Model 4200A-SCS Parameter Analyzer Reference Manual5-24 4200A-901-01 Rev. C / February 2017PMU amplitude sweep and step example (two-channel)In this two-channel example, one channel is sweeping while the other channel is stepping. Thesweeping 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 pulseamplitude steps with four step points. On the outer loop, PMU1-1 pulses the four steps of 1 V through2.5 V in 0.5 V increments.Operation modes and voltages for next figurePMU1-1 (blue waveform) PMU1-2 (light blue waveform)Operation modes Pulse Amplitude Step Pulse Amplitude SweepStart Voltage 1 0Stop Voltage 2.5 4Step Voltage 0.5 0.5Number of steps orsweep points4 9To preview the test, select the Test Settings tab, then select Advanced. You can preview a singlechannel or all channels in the test. The graph of the entire test (the lower graph of next figure) showsfour steps of nine points each. The sweep and step count displays the position of the cursor in theoverall test. This example has the number of pulses set to one.Figure 163: PMU Timing Preview, two channels
