Question for simultaneously acquiring the waveforms from 2 cards (PXI-5124)

Dear Sir/Madam, 

We have installed 2 cards (Card#1 and Card#2) of PXI-5124 into a chassis box PXIe-1071; and the waveform can be acquired successfully from single card with VS2013 C++ program. However, the waveforms can only be acquired sequentially at Card#1 first, and then Card#2 ( cannot be simultaneously acquired) because the program instruction “niScope_InitiateAcquisition ()” can only be handled by an instrument session “ViSession”.

Could you please share the solution how can we acquire the waveforms for each channel from 2 or more digitizer’s cards simultaneously?

Thank you.

Best regards,

Simon
