MATH<x>:SPECTral:PHASE
Description
This command sets or returns the units of a SpectralPhase 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.This command is equal to selecting Spectral Setup
from the Math menu, choosing the Phase tab, and then clicking the de-
sired Scale button.

Syntax 2
MATH<x>:SPECTral:PHASE?
Arguments
H DEGREES
This sets the SpectralPhase units to degrees.
H RADIANS
This sets the SpectralPhase units to radians.
H GROUPDELAY
This sets the SpectralPhase units to groupdelay, which commutes the
derivative of unwrapped phase spectrum. Units are expressed in sec-
onds.

Example 2
MATH2:SPECTral:PHASE?
This query might return
:MATH2:SPECTRAL:PHASE RADIANS
indicating that the SpectralPhase units for Math2 are set to radians.
