FREQ Channel
Preset 13.255 GHz
State Saved Saved in instrument state
Min Start Frequency of top window
Max The maximum Zoom Center frequency is the same as the maximum analyzer Center Frequency,
which is basically the instrument maximum frequency – 5 Hz. See the table under the Center
Freq key description.
Default Unit Hz
Initial S/W Revision A.07.01
Preset On entry to Trace Zoom, the Zoom Center frequency is the same as the analyzer Center
Frequency. So if you do a Mode Preset and then immediately go into Trace Zoom, Zoom Center
matches the Preset values listed in the table under the Center Freq key description.
Auto Tune
Auto Tune appears as the top key in the Frequency menu in the Normal and Spectrogram views
of the Spectrum Analyzer Mode.
Auto Tune is an immediate action key. When it is pressed, it causes the analyzer to change Center
Frequency to the strongest signal in the tunable span of the analyzer, excluding the LO. It is
designed to quickly get you to the most likely signal(s) of interest, with no signal analysis
knowledge required. As such, there are no configurable parameters for this feature. There are only
pre-selected values that work in most real world situations.
Auto Tune performs a Preset as part of its function, so it always returns you to the Normal View
and a preset state, although it does leave the AC/DC coupling and Single/Cont state unaffected.
You may see a slight pause before the signal of interest is presented at midscreen.
