4.2.1.3 TRANSMIT DEVIATION BALANCE (COMPENSATION) ALIGNMENT
RSS LOCATION: At the SERVICE MENU, press .
Refer to your radio service manual for the balanced attenuator alignment (compensation) procedure. This
procedure should only be attempted by qualified service personnel.
Compensation alignment is critical to the operation of signalling schemes that have very low frequency
components (that is, DPL) and could result in distorted waveforms if improperly adjusted.
Balanced attenuator alignment balances the modulation sensitivity of the VCO and reference modulation
(synthesizer low-frequency port) lines. It is a way of correcting for deviation sensitivity versus RF frequency
variations in the VCO. The transmit and receive bands are divided into frequency zones with a calibration point
(value) in each zone. Balanced attenuator alignment is required after replacing (or servicing) the controller board
or the RF board. Using the up/down arrow keys, adjust compensations per your radio service manual.
Performing this procedure automatically calculates compensation alignment.
The programming procedure, function key descriptions, and field definition are on the following page.
