How to interface to PXIe-6537 in acquisition mode?

[TomC_NGC]

I need to pass data in sustained bursts to a PXIe-6537.

As far as I can tell, the simplest way to do that is to configure the 6537 drivers for continuous acquisition.

On my driving end, I synchronize my 32bit data to a clock on PFI(5) that I generate. The clock acts as an enable for the 6537.

Is this correct?

Are there other recommendations on how to do this?

Tom,

How fast are you running?  In Pipelined Sample Clock timing mode, you get the fastest data rates but are required to provide a free running clock.  However, you can use a Pause trigger to tell the acquisition to hold off on grabbing data.  Alternately, if you are running in Sample Clock timing mode, the clock may be gated but response times on triggers may limit your data rate.

If you refer to section "Programming Your Device :: Choosing a Sample Timing Type", there is a table that briefly summarizes the differences between each of the timing types.
