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 > Source
— Source Enable ON OFF
— ON Turns ON the internal source.
—
OFF Turns OFF the internal source.
—
Source Mode Choose from the following:
— Tracking The internal source frequency can track the SA receiver.
Center frequency
Src is annotated on the screen
—
CW The source is set to a CW frequency independent from the SA
settings.
Srcw is annotated on the screen.
—
Coupled CW The source is set to a CW frequency, but that frequency
“tracks” the SA receiver Center Frequency settings. Therefore, the
signal always appears at center of the display. Srcp is annotated on
the screen.
—
Normalize ON OFF With Source Enable ON and Source Mode = Tracking,
Normalize ON stores the current measurement trace into Trace 4 in View
state as a reference trace. All subsequent trace measurements subtract
this Trace 4 reference trace, and therefore become relative to it.
SrcN is
annotated on the screen. Normalize is automatically turned OFF when the
frequency range or Resolution is changed. Learn more about Trace Display
States in
“Trace Display States (SA Mode)” on page 203.
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 210
and “Preferences” on page 780.
