SPERror | BREak
BSTart
Burst start. Sets the trigger to the begin of a data frame. The
frame start is the first start bit after the idle time.
SBIT
Start bit. The start bit is the first low bit after a stop bit.
NTHSymbol
Sets the trigger to the n-th symbol of a burst.
SYMBol
Triggers if a pattern occurs in a symbol at any position in a burst.
PATTern
Triggers on a serial pattern at a defined position in the burst.
To define the pattern, use TRIGger:A:UART:PLENgth and
TRIGger:A:UART:PATTern.
To define the position, use TRIGger:A:UART:POFFset.
PRERror
Parity Error: Triggers if a bit error occured in transmission.
FERRor
Triggers on frame error.
BREak
Triggers if a start bit is not followed by a stop bit within a defined
time. During the break the stop bits are at low state.
*RST:
SBIT
TRIGger:A:UART:PATTern <DataPattern>
Defines the bit pattern as trigger condition.
Parameter:
<DataPattern> Binary pattern with max. 32 bit. Characters 0, 1, and X are allo-
wed.
*RST: 1 = "00000001"
TRIGger:A:UART:PLENgth <PatternLength>
Defines how many symbols build up the serial pattern.
Parameter:
<PatternLength> Number of symbols
Bereich: 1 bis 4
Inkrement: 1
*RST: 1
