Commands Listed in Alphabetical Order
TRIGger:A:LO
GIc:CLAss
This command specifies what kind of logic trigger to use (either logic or
setup/hold). You also need to set the trigger type to
LOGIC using the command
TRIGger:A:T
YPe.
The
LOGIC argument sets the oscilloscope to trigger on logical combinations
of the chann
els (set using the
TRIGger:A:LOGIc:INPut commands as
well as TRIGger:A:LOGIc:FUNCtion). Youcanuseupto20channels
for a logic trigger (4 analog and 16 digital). With an MDO4000/B/C,
you can also use the internal RF power level in a logic trigger (requires
installation of an MDO4TRIG application module). You can perform logic
triggering using a clock; when TRIGger:A:LOGIc:INPut:CLOCk:SOUrce
is set to
one of the channels, the oscilloscope triggers when the specified
logical combination of the remaining channels is true during a transition
on the clock channel. You can also perform logic triggering without using
a clock (by setting TRIGger:A:LOGIc:INPut:CLOCk:SOUrce to
NONE),
so that the oscilloscope triggers when the specified logical combination
of data channels is met. Without a clock, you can also use the command
TRIGg
er:A:LOGIc:PATtern:DELTatime.
The
SETHold argument sets the oscilloscope to trigger on setup and hold
viol
ations between a data source and a clock source. The clocking and data
levels are used to determine if a clock or data transition has occurred. You can
use up to 20 channels as Setup and Hold trigger data sources (4 analog and 16
digital) using TRIGger:A:SETHold:DATa:SOUrce. You can use one channel
input as the clock signal (TRIGger:A:SETHold:CLOCk:SOUrce). The data
sources cannot include the waveform specified for the clock source.
