A/D STOP signal

The A/D STOP signal indicates a completed acquisition sequence. You can program this
signal to be available at any of the AUXOUT pins. The A/D STOP output signal is a
50 ns wide pulse whose leading edge indicates a DAQ done condition.

Waveform generation timing signals (PCI-DAS6014 only)

The signals that control the timing for the analog output functions on the PCI-DAS6014
are:
D/A START TRIGGER
D/A UPDATE
D/A EXTERNAL TIME BASE

D/A START TRIGGER signal

The D/A START TRIGGER signal is used to hold off output scans until after a trigger
event. Any AUXIN pin can be programmed to serve as the D/A START TRIGGER
signal. It is also available as an output on any AUXOUT pin.
When used as an input, the D/A START TRIGGER signal may be software selected as
either a positive or negative edge trigger. The selected edge of the D/A START
TRIGGER signal causes the DACs to start generating the output waveform.
The D/A START TRIGGER signal can be used as an output to monitor the trigger that
initiates waveform generation. The output is an active-high pulse having a width of
50 ns.
