Listen Time
While Tune & Listen is actively demodulating a signal, the SA does not sweep
and update the display. Listen Time sets the amount of time that the FieldFox
demodulates, then stops to perform a single sweep and update the display,
then again demodulates.
To select Listen Time:
—Press Meas Setup 4.
—Then Listen Time
.
— Enter a value using the numeric keypad, arrows, or the rotary knob.
Then select a multiplier key. Learn more in “Multiplier Abbreviations” on
page 2-14.
Volume Control

— Enter a value in percent between 0 and 100 (loudest) using the numeric
keypad, arrows, or the rotary knob.
— Volume can also be changed and easily muted from the System
menu.

Demod ON and OFF

sweeps, select the following:

Independent Source
A tracking generator, a popular option with Spectrum Analyzers, is a source
which always tracks the SA receiver.
Like a traditional tracking generator, the Independent Source feature can set
the internal FieldFox source to track the SA receiver frequency range. It can
also set the internal source to a CW frequency that is independent of the SA
frequency.
For best results, when using the independent source feature, the battery
saver features should be turned off. Refer to "Setting the Battery Saver to
OFF" on page 8-20 and to “Preferences” on page 18-7.
