two channel frequency measurement with NI USB 6259

[lanym]

I am currently measuring a pulse frequency using the "high frequency two counters" approach on a NI USB 6259.

Is it be possible to use an external trigger for the counters (setting the measurement time) in order to measure simultaneously two pulse frequencies on ctr0 and ctr1 ?

I have no idea how to do so with DAQmx

Thanks

Marc
