Chelectro Posted June 4, 2008 Report Share Posted June 4, 2008 I have a 6229 PCI DAQ connected to a CB-68LP connecting(PIN68 & PIN33)Analog Inputs. The electrical measure is an AUDIO differential signal, How can I performed a MATH function (V+)-(V-)? I can see both signal at 180 degrees dephase please see attachement. Quote Link to comment

If you are acquiring the signal as differential, then you will automatically get signal + with respect to signal -. If you can see both signals, then you are not acquiring a differential signal. Without looking up the channels, it sounds as if you have the wiring correct (the signal + should be connected to channel 0 and the signal - should be connected to channel 8).
