Hello,

So it looks like we can do this, the trick will be getting everything
to start on the same digital trigger.

Let=92s start with the DAQ side, with the pulse train generation.  For
this application we will need to use the new DAQmx drivers.  The
reason is that DAQmx supports digital triggers for pulse train
generation and the old driver does not.

There is an example that we should look at using.  It is the =93Gen Dig
Pulse Train-Finite-Dig Start.vi=94 example, which can be found in the NI
Example Finder.

Next, we can look at a different example for digitally triggering our
DAQ analog input.  A good example would be =93Acq&Graph Voltage-Int
Clk-Dig Start.vi=94

As for using the digitizer board, we should look at the Configured
Measurement shipping example that comes with NI-Scope, from here we
can select a digital trigger.

We should be able to start these three programs, apply a digital
signal, and see that they were all synchronized.

One other note, if you need to generate a digital start trigger, you
could wire in one of your digital I/O lines as the trigger and set it
high with a software call.

I know this is a lot of new information, just let me know what
questions you may have.

Best regards,
