PXIe-4499 simultaneous samples multi-modules

[bert2al]

Hello,

I have three PXIe-4499 simultaneous samples modules in a PXIe-1082 chassis.

I built a single AI voltage task which includes all the chnls on the three modules.

Do I need to do anything special to ensure all modules use the same sample clock?

Bert,

Channel expansion is by far the easiest way to synchronize channels in DAQmx.  If all channels are in the same task they will share a sample clock and start simultaneously.
