Details
This command sets the logic on which the trigger event detector and the output trigger generator
operate on the specified trigger line.
To directly control the line state, set the mode of the line to digital and use the write command. When
the digital line mode is set for open drain, the edge settings assert a TTL low-pulse.
Trigger mode values
Value Description
FALLing
Detects falling-edge triggers as input when the line is configured as an input
or open drain.
RISing
Detects rising-edge triggers as input when the line is configured as an open
drain.
EITHer
Detects rising- or falling-edge triggers as input when the line is configured as
an input or open drain.
Example
:DIG:LINE4:MODE TRIG,IN
:TRIG:DIG4:IN:EDGE RIS
Sets the input trigger mode for the digital I/O
line 4 to detect rising-edge triggers as input.

Usage
:TRIGger:DIGital<n>:IN:OVERrun?
<n>
Digital I/O trigger line (1 to 6)
Details
This command returns the event detector overrun status as 0 (false) or 1 (true).
If this is 1, an event was ignored because the event detector was already in the detected state when
the event occurred.
This is an indication of the state of the event detector built into the line itself. It does not indicate if an
overrun occurred in any other part of the trigger model or in any other detector that is monitoring the
event.
