MATH<x>:SPECTral:MAG
Description
This command sets or returns the units of the SpectralMag function in
the math string. The Math waveform is specified by x, which ranges
from 1 through 4 for four--channel instruments or 1 through 2 for two--
channel instruments. If you are using the standard math, this command
is equivalent to selecting Magnitude Spectrum from the Math menu and
then selecting the units that you want from the Scale button drop--down
menu. If you are using the Advanced Analysis functions, this command
is equivalent to selecting Spectral Setup from the Math menu, choosing
the Mag tab, and then clicking the desired Scale button.
