Does anyone have any experience using the NI USB-9215 module? A customer recently purchased one to use to capture peak force measurements, but is getting more noise than was expected. Upon investigation, the input noise specification is not good, 7 LSB for peak-to-peak. The expected signal range for the sensor being used is +/- 100mV. Our NI field engineer suggested oversampling and then averaging to remove some of the noise, which helped, but still does not remove enough of the noise. Hence, we are considering abandoning this module and going a different direction (a more costly direction). It appears that the 9215 is not the right DAQ with Signal Conditioning device for this application now, but I am wondering if anyone has tried to make it work for measuring low voltages at a 100 samples/second rate.
Has anyone else used this module? Have you had noise levels like this?
Thanks for your help,
Bob Young
