DT (Device Trigger)
Command Type:
Setting or query
Setting Syntax:
DT TRIG
DT GATE
DT SET
DT OFF
Query Syntax:
DT?
Query Response (one of the following):
DT TRIG;
DT GATE;
DT SET;
DT OFF;
Discussion:
T his command controls the instrument's response
to the Group Execute Trigger < GET > interface
message.
When a < GET > interface message is received and
the OT TRIG mode is set, the instrument produces
one cycle of signal if it is in TRIG mode, or it produces
a burst of cycles if it is in BURST mode.
If the trigger mode is set to GATE and < GET > is
received, the output is turned on until < GET > is
received again.
T he SET argument causes the instrument to wait for
a < GET > interface message before updating its
settings.
The power-on setting is DT OFF; the instrument
updates its settings without ·waiting for < GET > .
If DT is off and < GET > is sent, the error message:
206, "GET IGNORED"; will be returned.

Discussion:
T his que r y returns the error code for the last SRQ

code for the oldest error in the error queue if ROS
is OFF. Error code O (nothing to report) is returned
if the error queue is empty.
