Any Suggestions

Hi

I am using my 6062E Daq Card to trigger my NI-9234. I need to cut down the delay between the trigger pulse and the acquistion or maybe even calculate the delay. Any suggestions would be helpful

Thanks

Just a though but does that acquisition card allow No of samples before trigger?  i.e it acquires n samples before it recieves the trigger?

I am not sure

If so this will enable you to reduce the time between the trigger and the Acquisition, it should even allow you to get data before the trigger has occurred.

Even if your card doesnt support this, you could continuosly acquire the data into a circular buffer in software.  Then exit this condition when a trigger is applied.  This buffer could be written to contain a fixed amount of pre-trigger samples.

I'll have to try that
