RDS/RBDS generator input
The VS300 accepts ASCII or UECP data for its internal RBDS/RDS generator via RS-232 on the
RDS/RBDS
D-type connector (A1J5A). The data is framed and modulated on a 57 kHz sub-carrier,
which forms part of the composite signal.
Carrier frequency and pilot phase control
The VS300 provides carrier frequency and pilot phase control from a precision GPS reference on the
10MHz IN
BNC connector (A1J4B) (between 0.5 V and 2 V pk-pk sine wave input; 50
Ω
) and 1PPS
on the
ANALOG AUDIO/SCA3/1PPS
D-sub connector (A1J5B, pins 5 and 6; 5 V TTL input level,
10 k
Ω
).
Pilot sample output
The VS300 provides a 19 kHz pilot sample (500 mV pk-pk) on the
PILOT SAMPLE OUT
BNC
connector (A1J4A).
NOTE:
The VS300 also supports stand-alone RDS/RBDS operation. In this mode, RDS/RBDS
parameters are configured through the AUI.
