Hi every body,
I'm using a DIFF Input mode in a PCIe7841R. Iam making some tests with a voltge generator,
I have a very simple VI with only one Analoginput and an indicator to make sure that what iam generating with the voltage generator is the same as what iam reading.
Therefore I wired the Positiv signal (eg 2,5Volts) to AI0+ and the negativ to AI-, however the data I i get is oscillating i get -1,-2,0,-3,-2 also these are repeatd randomly , i see the same behaviour also when i set the voltage source off.
But when i use the Input Mode default i got some thing like 8177 but this is normal the 2 complement hex i can use an equation and get the right voltage. But i really need to use the Differential Mode.
I thank you very much for your help.
