Math Variables Control Window
Access this control window by selecting Set Math Variables… from the Math menu.
Overview
Use this control window to quickly set the math variables to use in
your math expression.
To Use
Use the 1-4 or 5-8 tab to access the variables that you want. Click
in the Var#= text box, and then use the multipurpose knobs to set
the value for the variable. Click Editor to access the Math Equation
editor.
Behavior
You can set or change the variable values in this control window.
To add a variable to a math expression, go to the math editor, and
click the VAR# button.
Spectral Setup Control Window
Access this control window from the Math menu Spectral Setup command, or by clicking Spect in the
Adjust Math Parameters control window.
Overview
Use these controls to set up a math waveform for spectral analysis. Use the controls on the tabbed
pages to create a spectral waveform, define the vertical scale units of the waveform, and to lock
waveforms together.
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.
