The advantages of using the DAC FIFO buffer for free-run, re-cycle mode analog
output are:
•
The DAS-1700AO’s digital trigger operates in retrigger mode, enabling
you to synchronize analog output with a recurring external signal.
•
Traffic on the memory bus is significantly reduced at high output rates.
•
The system response latency will be noticeably shortened.
•
The analog output timing will be immune to traffic on the memory and
I/O buses.
The disadvantages are:
•
You can’t change the analog output values while the analog output task
is running.
•
There is a delay while DriverLINX loads the FIFO.
•
Buffer-filled notification messages cannot be posted, as the hardware
does not permit detection of end-of-buffer conditions.
•
The STATUS operation cannot provide the “number of buffers
processed” report.
