Relation
Defines how the defined serial data pattern is compared with the acquired signal. The
instrument triggers if the acquired data word is equal or unequal the defined pattern.
Remote command:
TRIGger:SPI:DCONdition on page 444
Bit Offset
Sets the number of bits before the first bit of the pattern. These bits are ignored. The
first bit after CS or timeout is bit 0. For example, with bit offset = 2, bit 0 and bit 1 after
CS are ignored, and the pattern starts with bit 2.
Remote command:
TRIGger:SPI:DPOSition on page 444
