Displaying the Envelope of a Waveform
The test tool records the envelope (minimum and
maximum) of the live waveforms A and B.
Repeat the first three actions of 'Smoothing the
Waveform', and then do the following:
Highlight ENVELOPE.
Start monitoring the envelope of
the waveform.
The screen shows the resultant envelope in a gray
waveform. See Figure 1-12.
You can use ENVELOPE to observe variations in time or
amplitude of input waveforms over a longer period of time.
