Displays the menus to change the following parameters for offset
frequency settings and pass/fail tests: Offset, Start Freq, Stop Freq,
Sweep Time, Res BW, and Limits. Refer to the tables below for
default settings of particular radio standards of interest.

a. Fail Mask is set to Absolute and Rel Stop is set to Couple.
Specifies the resolution bandwidth used in measuring
and the power in the main channel.
Displays the type of power measurement reference
selected by Measure Type.
Total Pwr Ref is the power in the carrier that is used as
the reference in computing the relative power values
for the offsets. When Man is selected, this can be set
by the user. When Auto is selected, this is the
measured power in the reference carrier.
PSD Ref is the mean power spectral density in the
carrier that is used as the reference in computing the
relative power spectral density values for the offsets.
When Man is selected, this can be set by the user.
When Auto is selected, this is the measured mean
power spectral density in the reference carrier.
