I am acquiring a signal using USB 6281, which comes with a programmable gain. I wanted to know how to modify the gain. I looked into DAQmx channel using which I can set AI Max and Min. Is the gain adjusted when I modify these values?
Solved! Go to Solution.
from the DAQMx Pallette drop a Channel node. then from the LabVIEW Help:
Short Name: AI.Max
Property of DAQmx Channel
Specifies the maximum value you expect to measure. This value is in the units you specify with a units property. When you query this property, it returns the coerced maximum value that the device can measure with the current settings.
So My first answer was a slightly incorrect. I just tried this and sure enough if i set AI.Max to 3.2, then read AI.Max it reads 5. As 5V is the smallest range my particular device can use to read 3.2V
I hope that helps,
