R&S®SML / R&S®SMV03 Stereo Modulation (Option R&S SML-B5)
1090.3123.12 4.31 E-6
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 oder 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.
Query:
STEReo:DIRect? “MASK_STATE“
Response:
"1"
The MASK_STATE query provides information as to whether the RDS data
stream is linked to an error mask.
MODE
Description: Sets one of various transmit modes.
Command: MODE=x
Query: MODE?
Response: x
Value range: 1|2|3|4|5
1 = L: signal in left channel only
2 = R: signal in right channel only
3 = signal of equal frequency and phase in left and right channel
4 = signal of equal frequency and opposite phase in left and right channel
5 = different, independent signals in left and right channel
(5 is not possible if the internal LF generator is selected as source
(SRC = LFGen)
Example: Command:
STEReo:DIRect “MODE=1“
Only the signal of the left channel is transmitted.
Query:
STEReo:DIRect? “MODE“
Response:
"1"
