SA Mode Settings
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 about multiplier abbreviations.
Volume Control
To increase or decrease the Volume of the demodulated signal:
— Press Meas Setup 4
— Then Volume
— 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.
Learn more in “How to set the FieldFox Volume Control” on page 627 .
Demod ON and OFF
To quickly stop the audio demodulation and perform only the normal SA
sweeps, select the following:
— Press Meas Setup 4

Independent Source/Tracking Generator
This feature may require an option. For a comprehensive list, view the FieldFox
Configuration Guide at:
http://literature.cdn.keysight.com/litweb/pdf/5990-9836EN.pdf
A tracking generator, a popular option with Spectrum Analyzers, is a source
which always tracks the SA receiver.
For best results, when using the independent source feature, InstAlign and
the battery saver features should be turned off. Refer to “How to Access
Individual Alignments” on page 185 and “Preferences” on page 637 .
