Parameter:
<Pattern> String with max. 7 or 10 characters, depending on the address
length. Characters 0, 1, and X are allowed. If you define a pat-
tern shorter than the address length, the missing LSB are filled
with X.
Beispiel:
TRIG:I2C:ADDR "10110"
Sets the 7 bit address pattern 10110XX.
TRIGger:I2C:DATA <Pattern>
Defines the data pattern as trigger condition. Enter the words in MSB first bit order.
Parameter:
<Pattern> String with max. 4 bytes in binary format. Characters 0, 1, and X
are allowed. If you define a pattern with incomplete byte, the
missing LSB are filled with X.
Beispiel:
TRIGger:I2C:DATA '11111111000000001111'
TRIGger:I2C:DATA?
<-- 11111111000000001111XXXX
TRIGger:I2C: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.
Parameter:
<Relation> EQUal | NEQual
*RST: EQUal
TRIGger:I2C:DPOSition <ByteOffset>
Sets the number of bytes before the first byte of the data pattern. These bytes are
ignored.
Parameter:
<ByteOffset> Bereich: 0 bis 4095
Inkrement: 1
*RST: 0
