I've created a VI that captures analog data from one channel on the AD2. AD2 has an optical sensing system connected to the input. I can successfully collect data, but for some reason, the noise values of the original WaveForms software and LabVIEW do not fit. There are noise level up to 2 mV in WaveForms and up to 4 mV in LabVIEW. Does somebody know what causes it? Does AD2 use any special software filter? The pictures of waveforms are in the attachment.
Thank you very much for your answers
