Transmit Deviation
Balance Alignment
From the MAIN MENU, press F2 twice and then F4 to access this
screen.
Balanced Attenuator Alignment is required after replacing (or servicing) the
Controller Board or the RF Board. Balanced attenuator alignment
balances the modulation contributions of the low and high frequency
portions of a baseband signal.
Refer to your Radio Service Manual for the Transmit Deviation Balance
Alignment (Compensation) procedure. This procedure needs to be
performed at multiple frequencies to allow for proper alignment across
the entire RF band. The transmit and receive bands are divided into
frequency zones with a calibration point (value) in each zone.
Compensation alignment will be automatically calculated when you
perform this procedure.

Caution
This procedure should be attempted only by qualified
service personnel. Failure to perform alignment
procedures properly may result in seriously degraded
radio or system performance.
Proper compensation alignment is critical to the
operation of signalling schemes that have very low
frequency components (DPL for instance) and could
result in distorted waveforms if improperly adjusted.
