7.19 Direct Commands for the Stereo/RDS Coder Option
R&S SMB-B5
The direct command allow to access all functions of the stereo coder option.
Some of the functions are also available via SCPI commands. In this case, it is recom-
mended to use the SCPI commands in order to keep the settings of the R&S SMB and
the stereo coder synchronized. Direct command for which a SCPI command is availa-
ble are marked with “for documentation reasons only” and the SCPI command is given.
The direct commands are sent to the Stereo/RDS Coder with
[SOURce:]STEReo:DIRect "command string"
.
Information is queried with
STEReo:DIRect? "command string"
.
All parameters are string parameters, this is the reason why all of them have to be sent
in qotation marks ( " – characters are part of the full direct command ! ).
Prior to using the stereo coder, the stereo modulation of the R&S SMB has to be
switched on with command
SOURce:STEReo:STATe ON
. The SCPI command
SOURce:STEReo:AUDio:FREQuency
sets the LF-Generator frequency and com-
mand
SOURce:STEReo:MMF
limits the modulation frequency. These commands have
no counterpart in the direct commands.
7.19.1 Remote-Control Commands
STEReo:DIRect
"<FFG>=<RetrNumb>,<DataSeq#1>,<DataSeq#2>,..."
STEReo:DIRect?
"<FFG>"
Transmits data via free format groups (FFGs). A free format group can be filled with
any desired data. (5 bits in block B and 16 bits each in blocks C and D of the group).
