"How do I use AISampleChannels to get 16 analog inputs?"

[ChrisN]

"I want to do 8 differential inputs but I'm wondering if I can use one call to AISampleChannels(not sure about 2nd parmeter of this function) and graph my data to 4 individual graphs. I use LabWindows/CVI with a PCI-6025E board on a Win98 machine.

Thanks in advance"

Hello,
Yes, you can use AISampleChannels to do what you want. The second parameter is for the list of the channels you want to read from. For example, if you want to read channel 0 to 2, you'll have "0:2", or "0,1,2". The last parameter will contain the data for all the channels, in the order you specified in the second parameter.

You can right click on each parameter control on the function panel and it opens the help file for the parameter.
