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.
