Syntax 1
TRIGger:A:LOGIc:CLAss {PATtern|STATE|SETHold}
Syntax 2
TRIGger:A:LOGIc:CLAss?
Arguments
H PATtern
In four--channel instruments, this argument sets the instrument to trig-
ger when the specified logical combinations of channels 1, 2, 3, and 4
are met. On two--channel instruments, only channel 1 and channel 2
are available.
H STATE
In four--channel instruments, this argument sets the instrument to trig-
ger when the specified conditions of channels 1, 2, and 3 are met after
the channel 4 (clock) condition is met. On two--channel instruments,
only channel 1 and channel 2 (clock) are available.
H SETHold
This argument sets the instrument to trigger on setup and hold viola-
tions between a data source and a clock source. Use one channel input
as the clock signal and a second channel input as the data input. The
clocking and data levels are used to determine if a clock or data tran-
sition has occurred.
