TRIGger:A:LOGIc:PATtern:INPut:CH4
Description
This command sets or queries the A logic trigger input for channel 4 in
four--channel instruments only. The command specifies the logic value
used when the pattern trigger detects the threshold level. Sending this
command is equivalent to selecting Logic Pattern from the Trig menu
and then choosing the desired logical input from the Ch4 drop--down
list, which is located in the Input Threshold group box.
To set or query the A logic trigger input for a two--channel instrument,
see TRIGger:A:LOGIc:PATtern:INPut:CH2.

Syntax 1
TRIGger:A:LOGIc:PATtern:INPut:CH4 {HIGH|LOW|X}
Syntax 2
TRIGger:A:LOGIc:PATtern:INPut:CH4?
Arguments
H HIGH
This specifies the logic high.
H LOW
This specifies the logic low.
H X
This specifies a ”do not care” state.
Example 1
TRIGger:A:LOGIc:PATtern:INPut:CH4?
This query might return
:TRIGGER:A:LOGIC:PATTERN:INPUT:CH4 HIGH
indicating that the logic input for channel 4 is logic high.
Example 2
TRIGger:A:LOGIc:PATtern:INPut:CH4 HIGH
This command sets the A logic trigger input to logic high for channel 4
when the logic class is set to PATtern. When the threshold level is de-
tected, HIGH places a 1 on the channel 4 input to the selected function.
