R&S SMB100A
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
ARI Deviation - Stereo Modulation
Sets the frequency deviation of the ARI subcarrier signal.
Remote command:
[:SOURce]:STEReo:ARI[:DEViation]
ARI Identification - Stereo Modulation
Selects the generated identifiers of the ARI signal.
"Off"
"DK"
"BK"
"DK+BK"
Remote command:
[:SOURce]:STEReo:ARI:TYPE
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]
RDS Settings
The RDS (Radio Data System) is configured in the RDS Settings section, RDS is a
communications protocol standard from the European Broadcasting Union for sending
digital information embedded in conventional FM radio broadcasts. The RDS system
standardises 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

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.
The message identification (Durchsagekennung) is generated in addi-
tion (low-frequency 30% AM). It signalizes that a traffic message is
currently broadcasted.
The area identification (Bereichskennung) is generated in addition
(60% AM). This code is used to identify the geographical region cov-
ered by the radio station. The specific code is selected below.
The area and message identification are generated in addition.
