Trigger In
You can configure each DAC on the module to trigger off an externally
provide Trigger In that has a pulse width greater than 100 ns. The Trigger
In line is 5V TTL tolerant.
Trigger Out
The DAC module can source a TTL level Trigger Out. Trigger Out has a
pulse width between 5 and 10
Auto-Calibration
The 34951A features auto- calibration (auto- cal). Upon receipt of the
CALibration:MODule? command, you can adjust all four channels of the
DAC module. The adjustments, performed under complete control of the
34980A, require approximately one minute per module.

Before performing an auto calibration, be sure to allow a one- hour
warm- up of the DMM and 34951A module. The adjustment is valid for 90
days for temperatures within 5
calibration constants to be saved, calibration security must be off.
Otherwise, the new calibration constants can be used while power is on.
But when power is lost, the DAC module will revert to using the
previously stored calibration constants. For SCPI programming examples
for the auto- cal, refer to

The line between external Trigger Out and external Trigger In is

shared. You can use the external Trigger Out to provide the external
Trigger In signal. However, both a user-supplied external trigger and
the 34951A Trigger Out cannot drive the line at the same time.
Because the auto-cal uses the internal DMM, do not route signals
on ABus1 when performing an auto-cal of a DAC module. Do not
apply a signal to ABus1 via the Analog Bus connector on the rear
of the mainframe (pins 4, 5, and 9). The auto-cal will abort if a
signal is detected on ABus1.
