Viewing Synthesized Waveforms
To view the synthesize waveforms based on the sampled harmonic spectrum,
click on the button on the local toolbar to view non-overlapped voltage
and current waveforms, or click on the button to view them overlapped.
PAS shows a pair of 4-cycle voltage and current synthesized AC waveforms
for a single phase.
To select the channels you want to view, click with the right mouse button on
the waveform window, select “Channels...”, check the channels for the phase
you want displayed, and then click OK.
