Parameters:
<TriggerType> STBT | PCKS | DATA | PRER | STPerror | BRKC
STBT = start bit
PCKS = frame start
PRER = parity error
STPerror = stop error
BRKC = break condition
DATA:: data. To set up the trigger condition, use TRIGger:
UART:DATA, and TRIGger:UART:DCONdition.
For details, see "UART Trigger" on page 184.
*RST: STBT
TRIGger:UART:DATA <Pattern>
Defines the data pattern as trigger condition. Enter the words in MSB first bit order.
Parameters:
<Pattern> String with max. 8 bit in binary format. Characters 0, 1, and X
are allowed.
Example:
TRIGger:UART:DATA '1x11'
TRIGger:UART:DATA?
1X11
TRIGger:UART:DCONdition <Relation>
Defines how the specified data pattern is compared with the acquired signal. The
instrument triggers if the acquired data is equal or unequal to the pattern.
Parameters:
<Relation> EQUal | NEQual
*RST: EQUal
