We are having trouble with our NI USB-6343 device. Using AnalogOut, the output values supported are only -4 to +4 volts. We cannot get any voltage values above or below to work properly. Can someone please tell me what could be wrong, as we should be seeing values from -10 to +10 volts.
Solved! Go to Solution.
That behavior isn't right. How are you measuring the output? Do you have a load on the terminal? The card can only drive 5 mA so your voltage would probably start dropping if you are pulling more current.

800 Ohm (or 1k) load?
Thank you for the answers. The 50ohm impedence was causing some clipping on the top and low peaks. We have since solved the problem by connecting a voltage follower circuit to overcome the impedence issue.
