TRIGger:A:LOGIc:THReshold:CH<x>
Description
This command sets or queries the A logic trigger threshold voltage for
the channel, specified by x, which ranges from 1 through 4 for four--
channel instruments or 1 through 2 for two--channel instruments. This
command is equivalent to selecting A Event (Main) Trigger Setup from
the Trig menu, choosing a logic trigger type, such as State or Pattern,
and setting the Input Threshold voltage for the desired channel.

Syntax 1
TRIGger:A:LOGIc:THReshold:CH<x> <NR3>
Syntax 2
TRIGger:A:LOGIc:THReshold:CH<x>?
Argument
H <NR3>
This specifies the threshold voltage.
Example 1
TRIGger:A:LOGIc:THReshold:CH3?
This query might return
:TRIGGER:A:LOGIC:THRESHOLD:CH3 1.2000E+00
indicating that the A logic trigger threshold voltage for channel 3 is
1.2 V.
Example 2
TRIGger:A:LOGIcTHReshold:CH2 3.0E-3
This command sets the A logic trigger threshold voltage for channel 2
to3mV.
