PXIe 4082 Sensitivity measurments

[ASTDan]

Hello,

I am trying to determine the sensitivity (minimum value instrument can measure) for Resistance and Inductance measurements for the PXIe 4082.

Here is the spec sheet

https://www.ni.com/docs/en-US/bundle/pxie-4082-specs/page/specs.html

It lists the minimum range but not the sensitivity. 

Thanks

I'm not sure if I'm understanding your question correctly.  When you say sensitivity for resistance are you saying Ohm/volt sensitivity?  You may want to take a look at the spec overview for the PXIe-4082 sensitivity:

And a couple more additional resource below:

Hello Jonathan,

I am looking for the sensitivity

2. Sensitivity

Sensitivity is the smallest unit of a given parameter that can be meaningfully detected with the instrument when used under reasonable conditions. For example, assume the sensitivity of a DMM in the volts function is 100 nV. With this sensitivity, the DMM can detect a 100 nV change in the input voltage.

Where or how can you determine this value for the PXIe 4082

I am looking at resistance and inductance measurements

Thanks

I just realized that you posted this on the incorrect forum.  You may have better luck here.  Regarding an answer to your question this isn't so straightforward and I would suggest you create a service request with us if you have a service agreement.  I'll try to look into this a little deeper but I think you'll get additional hits on your post if you post this in the correct forum post. 

Thanks,

OK I created a service request.

I will post my answer when I get a response.

Thanks
