ARI State - Stereo Modulation
Activates/deactivates the ARI signal generation. ARI signals can be generated simulta-
neously with MPX and RDS signals.
Remote command:
[:SOURce]:STEReo:ARI:STATe on page 369
ARI Deviation - Stereo Modulation
Sets the frequency deviation of the ARI subcarrier signal.
Remote command:
[:SOURce]:STEReo:ARI[:DEViation] on page 370
ARI Identification - Stereo Modulation
Selects the generated identifiers of the ARI signal.
"Off"
Only the 57 kHz subcarrier is generated (Senderkennung). It marks the
stations which broadcast traffic programs and enables the receiver to
recognize the frequency as being ARI-capable.
"DK"
The message identification (Durchsagekennung) is generated in addi-
tion (low-frequency 30% AM). It signalizes that a traffic message is cur-
rently broadcasted.
"BK"
The area identification (Bereichskennung) is generated in addition
(60% AM). This code is used to identify the geographical region covered
by the radio station. The specific code is selected below.
"DK+BK"
The area and message identification are generated in addition.
Remote command:
[:SOURce]:STEReo:ARI:TYPE on page 369
ARI BK - Stereo Modulation
Selects the specific area identification (BK) code of the ARI signal. The six letters (six
different frequencies) identify a specific region in each country.
Remote command:
[:SOURce]:STEReo:ARI:BK[:CODE] on page 368
RDS Settings
The RDS (Radio Data System) is configured in the RDS Settings section, RDS is a com-
munications protocol standard from the European Broadcasting Union for sending digital
information embedded in conventional FM radio broadcasts. The RDS system standard-
ises several types of transmitted information, including time, track/artist info and station
identification.
RDS State - Stereo Modulation
Activates/deactivates the RDS signal generation. RDS signals can be generated simul-
taneously with MPX and ARI signals.
Remote command:
[:SOURce]:STEReo:RDS:STATe on page 375
