STEReo:DIRect
"MASK=<NumbGroups>,<ErrFreeGroups>,<BitMaskBlcA>,<BitMaskBlcB>,<Bit
MaskBlcC>,<BitMaskBlcD>"
STEReo:DIRect? "MASK"
Sets a bit mask to generate defined bit errors in the RDS data stream.
Setting parameters:
<NumbGroups> Number of groups to be masked.
If <NumbGroups> = 0, the RDS groups are continuously linked
to the error mask.
If <NumbGroups> ≠ 0, this value is decremented after each
errored group transmitted. When zero count is reached, no fur-
ther errored groups are transmitted, and STEReo:DIRect is set
to "0".
Range: 00 to FF (hexadecimal values)
<ErrFreeGroups> Number of error-free groups to be inserted after each errored
group.
Range: 00 to FF (hexadecimal values)
<BitMaskBlc> <BitMaskBlcA>,<BitMaskBlcB>,<BitMaskBlcC>,<BitMaskBlcD>
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.
Range: 0000000 to 3FFFFFFF
Example:
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".
STEReo:DIRect "MASK_STATE=<State>"
STEReo:DIRect? "MASK_STATE"
Switches on or off the transmission of defined bit errors in the RDS data stream.
Setting parameters:
<State> 0 | 1
