Trigger setups Set up an SPI bus trigger
NOTE. For low-speed serial triggering on data streams, the instrument implicitly pads the MSB side of the
entered v alue, up to the next byte, with "don't care" values (X). To trigger on a two-byte message, you must
enter don't ca
re values explicitly up to the desired size.
For example, a binary entered value of 01 is equivalent to XXXX XX01, whereas a two-byte message
would be ente
redasXXXXXXXXXXXXXX01.
When you click on the trigger window controls, the trigger graphic
(see page 386) shows the trigger
sequence.
