Simultaneous Vibration DAQ with multiple NI9234 AI Card on cDAQ-9185 config?

[sez]

I currently have a triaxial accelerometer that I use with NI9234 that is capable of doing 51.2 kS/s/channel. I would like to add three more NI9234 cards to the system to increase the number of accelerometer DAQ points.  How is it possible to simultaneously acquire data from all the NI9234 without jitter/latency? Is it possible to do it by increasing the number of channels on my task and still using the same sample clock on my existing AI accelerometer task? Thanks for your input on how to proceed with the DAQmx configuration.

Make sure all you 9234s are in the same chassis and it should be pretty easy.

Hi Sez,

I will have similar application! Was your setup successful in terms of simultaneous measurements with 3 NI9234 cards on one USB Chassis.

Thanks,
