Viewing Waveforms
Waveforms can be displayed in five different views: as
overlapped waveforms on a common time axis, individual
waveforms using separate time axes, as a cycle-by-cycle plot
of RMS values, as a frequency chart for voltage channels, and
as a harmonic spectrum in a graph or in a table view.
Each waveform window has a local toolbar from where you
can open another window to examine the waveforms in a
different view. When you move to another waveform record,
all views are updated simultaneously to reflect the changes.
You can open all five views together to analyze different
properties of the waveform like a wave shape, waveform
disturbance, unbalance, or spectrum.
Viewing a Waveform Graph
When you open a new file, PAS shows you a waveform graph
with non-overlapped waveforms.
Click on the button on the local toolbar to see overlapped
waveforms; click on the button for non-overlapped
waveforms.
