Synchronize PXI-1050 and cDAQ-9174

[TC_Magic]

I have a PXI-1050 and cDAQ-9174.

The PXI has the following analogue input boards:

2 x SCXI-1102C

The cDAQ has the following analogue boards:

2 x NI-9105

My question is how to I sync the analogue inputs so I can have one task?

I want to sample a 1000 samples a second.

Thanks

Hi TimS,

The way to synchronise multiple chassis in this way is to export a trigger signal and timebase so that they synchronise up. The SCXI bus is connected to the PXI bus by a DAQ card integrated into the chassis so you should be able to route the trigger buses to that to synchronize timing, however to import or export a trigger for a PXI you will need a triggering card, there is a good article on multi chassis synchronization which is similar to what you are doing on our website:

In terms of running them in a single DAQ task, I do not believe that is possible as you would have issues with the DAQmx driver running a single task on seperate hardware and routing signals.
