Tuning the Rx Audio Level Set
The procedure outlined in this section is used to set the receive output audio level from the SLR 8000
Base Station/Repeater for a given RF deviation of the received RF signal. Perform this procedure any
time the Rx audio level needs adjustment.
Base Station/Repeater for a given RF deviation of the received RF signal. Perform this procedure any
time the Rx audio level needs adjustment.
Procedure:
1 Connect the base station/repeater's receiver antenna port to the Communication Analyzer.
2 Power the base station/repeater from either an AC or DC source.
3 Launch the Tuner application.
4 To read the softpot values, click Read.
5 Under the RX menu in the tree view, select Rx Rated Volume.

6 Set the Communication Analyzer to output a -47 dBm RF signal modulated with a 1 kHz tone at
60% of full deviation on the tuning frequency. The tuning frequency is the value displayed on the
Tuner GUI under the heading of "Frequency Points".
Tuner GUI under the heading of "Frequency Points".
NOTICE:
The Tuner aligns this parameter in a 12.5 kHz channel spacing, so 60% is 1.5 kHz of
deviation. If the CPS is set for 25 kHz operation, the base station/repeater automatically
scales the deviation by a factor of two when it is outside the Tuner application.
