TRIGger:A:LOGIc:INPut:CH<x>
Description
This command sets or queries the A logical input for the logic trigger
channel specified by x. The value of x ranges from 1 through 3 for
four--channel instruments. For two--channel instruments x can only be
1. Note that CH4 on four--channel instruments or CH2 on two--channel
instruments cannot be set or queried with this command. For details
about setting this channel, see TRIGger:A:LOGIc:PATtern:INPut:CH4
or TRIGger:A:LOGIc:PATtern:INPut:CH2. This command is equiva-
lent to selecting A Event (Main) Trigger Setup from the Trig menu and
then choosing the desired logical input from the Ch<x> drop--down list,
which is located in the Input Threshold group box.
