Generate signals simultaneously on two channels (PXIe-5451)

[CyGa]

Hi !

I'm trying to generate 2 different signals on the two output port of my PXIe-5451.

Signals are streamed from data read in TDMS file.

I'm able to generate 1 signal on 1 channel. But I cant' figure out how to fill the memory with data for my 2 channels and let the generator push these data simultaneously or their respective outputs !

Any help can be provided ? Maybe an example ?!

Thanks !

Hello Mr. Gambini,

You can find all the information to perform this operation here:

http://zone.ni.com/reference/en-XX/help/370524P-01/siggenhelp/5451_ni_5450_multichannel_allocation/

Particulary: 

"To write waveform data to both channels at once, you must first interleave the data. Once the data is interleaved, call the niFgen Write Waveform (poly) VI or one of the niFgen Write Waveform functions with the Channel parameter set to "0,1"."

Hi !

This method works but only half of the onbaord memory is accessible !
