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/5992-3701EN.pdf
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.
Independent Source can be enabled ONLY when the FieldFox is in SA mode.
To view the internal source, you must connect a cable or device between the
RF Output connector and the RF Input connector.
How to make Independent Source Settings
—Press Measure 1
—Then Source
— Source Enable ON OFF
— ON Turns ON the internal source.
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 148 and “Preferences” on page 230.
