Spectral tracking
From the Math menu, select Advanced Spectral; then open the Tracking tab.
Use these controls to lock two math waveforms together. This is useful when you want to generate both a magnitude waveform
and a phase waveform from the same source.
When you lock the spectral controls together, any changes you make to one math waveform are also made to the other math
waveform.
You can only lock Math1 with Math2 and Math3 with Math4.
Locking is useful, for example, when Math1 is the spectral magnitude and Math2 is the spectral phase of the same signal.
Locking forces the magnitude and phase waveforms to track if you change the spectral controls.

Set up the spectral vertical axis
From the Math menu, select Advanced Spectral; then open the Vert Axis tab.
To use. Use these controls to specify the vertical scale for advanced spectral waveforms. The available selections will vary
depending on the settings you make in the Create/Edit tab.
