Field Descriptions
SINAD
This field is only visible when SINAD is selected from the AF Freq field on the
display area of the TX TEST screen. This field displays the measured SINAD of
the input signal.
Tune Freq
RF Analyzer tune frequency sets the center frequency for the RF signal to be
analyzed.
Operating Considerations
If the Tune Mode is set to Auto, the frequency is set by the Test Set by finding
the strongest RF signal above −36 dBm within the full bandwidth of the RF
Analyzer.
If the
Tune Mode is set to Manual, the operator must enter the desired frequency.

field description (this page)
Tune Mode
This field selects automatic or manual tuning of the RF Analyzer.
Auto causes the RF Analyzer to find the signal with the greatest amplitude
>-36 dBm, and set the tune frequency for that signal.
Manual 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 to prevent the Tune Freq
from changing when the signal is no longer applied.
