DEV SCA
(CONF.DEV.SCA) – read/write
With this parameter, set the SCA deviation (auxiliary sub-carrier other than RDS), as needed.
From 0 to 25.5 kHz
Interaction between the various components according to the input type:
In all cases described below, the transmitter configuration is as follows:
Audio = 67.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz.
In the case of audio inputs (analog or AES), the set MPX represents the total of audio, pilot and RDS. If the
RDS is disabled, the audio is automatically adjusted with +4 kHz.
Ex 1: set
MPX = 75 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz.
If the RDS is enabled:
Audio = 63.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz
If the RDS is disabled:
Audio = 63.5 + 4 = 67.5 kHz
Pilot = 7.5 kHz
In the case of MPX inputs, if the RDS is disabled,
the audio cannot be adjusted
.
Ex 2: inject stereo MPX + RDS with:
Audio = 63.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz.
If the RDS is disabled:
Audio = 63.5 kHz
Pilot = 7.5 kHz
RDS on the MPX input:
Audio = 63.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz
With internal RDS:
Audio = 63.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz
