I'm directly measuring the voltage from a 1.5V battery for example using differential input with unshielded 1m cable from the terminator board to card. Even using the Test Panels with my DAQCard 6024-E PCMCIA card in my laptop I see lots of noise, +/- 1 volt or more. When I remove the AC power and just run on the laptop batteries, the noise is reduced, but still evident. In my vi's I get around it by averaging, but is there any other way to reduce the noise?
