Analyzing Wavef
orms
Use the following procedure to build an advanced spectral math expression.
1. Select Ma th > Ad vanced Spectral....
2. Select the math waveform that you want
to define.
3. Click the type of spectral waveform
that you want to create. To redefine a
waveform, click Clear.
4. Select the source waveform.
5. Adjust the spectral waveform, using the
controls in the Spectral Setup control
window and use the multipurpose knobs.
6. You can view time-domain and
frequency-domain waveforms
simultaneously.
Use Gating to select only a portion of
the time-domain waveform for spectral
analysis. (See page 53, Gating.)
