NI 9219 bandwidth

[stevem80]

What is the bandwidth of the analog filter preceding the ADC?

Hi stevem80,

What is your overall application?

[stevem80]

Measuring voltage and temperature (thermocouples and RTDs)

Ok, and just out of curiousity, which part of your application would obtaining the filter bandwidth help with?

[stevem80]

I would like to know the frequency response, i.e., the -3dB point.

stevem80,

Generally we keep information such information internal.

Maybe my question wasn't phrased correctly.  What is the signal bandwidth of the NI 9219?

[Joel-I]

Hi stevem80,

The signal bandwidth is 0-100Hz, and the analog filter's bandwidth is well above this range and should not effect any measurements you obtain.
