R&S SML Commands for Stereo/RDS Coder R&S SML-B5
General Information
This document contains a list of commands for the optional Stereo/RDS Coder R&S SML-B5 for the
Signal Generator R&S SML01.
Commands are sent to the Stereo/RDS Coder
with STEReo:DIRect: ["command string"].
Information is queried with STEReo:DIRect? ["command string"]
All commands are to be terminated with CR.
Uppercase/lowercase: Uppercase and lowercase letters are used to identify the long form and
short form of the keywords of the commands given in the manual. The instrument itself does not
distinguish between the two types of characters.
Commands
1A=, 3A=, 5A=, 6A=, 7A=, 8A=, 9A=, 10A=, 11A=, 12A=, 13A=
Description: 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).
Command: 1A=WW,xxxxxxxxxx,yyyyyyyyy,...
or 1A=00: erases the data
Query: 1A?
Response: xxxxxxxxxx,yyyyyyyyy,...
Value range: WW = number of retransmissions
x, y = 0000000000 to 1FFFFFFFFF
(10 ASCII coded hexadecimal characters each)
Max. 20 different data sequences can be defined.
Example: Command:
STEReo:DIRect "1A=01,0123456789,1FFFFFFFFF"
Fills a queue with the data "0123456789,1FFFFFFFFF".
The data is sent in consecutive order in group 1A after group 1A is added to
the group sequence (see "GS" command below).
Query:
STEReo:DIRect? "1A"
Reads the data of group 1A.
Response:
"01,0123456789,1FFFFFFFFF"
Important: 10 characters must be specified each for x and y. Leading zeros, if any,
must also be specified. The command described here only causes a
queue to be filled with data for a specific group. The data will only be sent
when the group in question is added to the group sequence with the
"GS" command.

MASK
Description: Sets a bit mask to generate defined bit errors in the RDS data stream.
Command: MASK=xx,yy,aaaaaaa,bbbbbbb,ccccccc,dddddddd
Query: MASK?
Response: xx,yy,aaaaaaa,bbbbbbb,ccccccc,dddddddd
Value range: xx = 00 to FF (hexadecimal values), corresponding to number of groups to be
masked.
If xx is set to zero, the RDS groups are continuously linked to the error mask.
If xx is set to a value other than zero, this value is decremented after each
errored group transmitted. When zero count is reached, no further errored
groups are transmitted, and MASK_STATE is set to "0".
yy = 00 to FF (hexadecimal values)
Number of error-free groups to be inserted after each errored group
a, b, c, d = 0000000 to 3FFFFFFF
Hexadecimal bit mask for blocks A, B, C and D of the RDS groups.
For each block, 26 bits (16 data bits and 10 CRC bits) have to be entered in
hexadecimal code.
Example: Command:
STEReo:DIRect "MASK=09,01,0000001,0000000,0000000,0000000"
In nine RDS groups, the least significant bit of the CRC code of block A is
inverted, i.e. an errored bit is sent. After each errored group, one error-free
group is inserted. After transmission of the complete sequence, MASK_STATE
is set to "0".
With the command MASK_STATE=1, the above sequence (9 errored groups
with one error-free group inserted after each errored group) is retransmitted
once.
Then, MASK_STATE is again set to "0".
Query:
STEReo:DIRect? "MASK"
Response:
"09,01,0000001,0000000,0000000,0000000"
MASK_STATE
Description: Switches on or off the transmission of defined bit errors in the RDS data stream.
Command: MASK_STATE=x
Query: MASK_STATE?
Response: x
Value range: x = 0 or 1
Example: Command:
STEReo:DIRect "MASK_STATE=1"
With the command MASK_STATE=1, a sequence of errored groups as defined
by the MASK command is retransmitted once if the number of groups to be
masked is other than zero. Then, MASK_STATE is automatically set to "0".
If the number of groups to be masked is equal to zero in the MASK command
(which means continuous error transmission), the masking function can be
switched off with MASK_STATE=0.
