Math setups Set up the frequency spectral controls
Overview
Use the controls in this window to set up a dvanced math waveforms for spectral analysis. Using the tabs,
you can create a spectral waveform, define the vertical units, and adjust the measurement parameters.
You can also lock waveforms together.
To use
For informa
tion on the controls, click the buttons.
After you create the spectral waveform, use the controls on the right side of the control window to position
and adjust the waveform so that you can view the data you are interested in.
You can operate the instrument and view spectral (FFT) waveforms using the time-domain controls, gating
controls, or frequency domain controls. Some of these controls are interactive; making changes with one
set of controls will sometimes change settings in another control set.

Set up the frequency spectral controls
From the Math menu, select Adva nced Spectral, or click Advanced in the Math Setup control window.
To use
Click in an entry box, and then use the multipurpose knobs to set the Center Freq (see page 248), Freq
Span (see page 248),andRes BW (see page 249).
Click Full to set the fre quency span to full.
