Field Descriptions
Tune Freq
RF analyzer tune frequency sets the center frequency for the RF signal to be
analyzed.
Operating Considerations
If the Tune Mode field is set to Auto, the frequency is set by the instrument.
If the
Tune Mode is set to Manual, the operator must enter the desired frequency.

field description, on page 297
Tune Mode
This field selects automatic or manual tuning of the RF Analyzer.
Auto tuning causes the RF Analyzer to find the signal with the greatest amplitude
above −36 dBm, and set the tune frequency for that signal.
Manual tuning requires the operator to set the tune frequency for the RF signal to
be analyzed.
Operating Considerations
Changing the Tune Mode also changes the RF frequency display. Automatic
tuning enables the TX Frequency measurement. Manual tuning enables the
TX Freq Error measurement.
After autotuning to the desired signal, select
Manual tuning to prevent the
Tune Freq from changing when the signal is no longer applied.
