USB 4431 analog gain ranges

[JohnDoe23]

Hi, I would like to know what gain values are used for various signal ranges in the USB 4431 DAQ.

Here is a similar table of what I'm looking for, but I could only find this for PCI-6030E: http://digital.ni.com/public.nsf/allkb/E69C47B0BB063B548625794A004B8354

Thanks.

As far as I know, there is only a single range so could you link to manual that told you it had multiple ranges? Or are you aking without reading the documentation?

Dear JohnDoe23!

You can set the range of Your measurement with the DAQmx Create Virtual Channel (VI).

It has 2 inputs: Minimum and maximum value.

API sets the Programable Gain Amplifier depending on the values You sepcify. 

The NI 4431 has an input range of ±10 Vpk, so You can set any values in this the range. 

Se the specs: http://www.ni.com/pdf/manuals/372485e.pdf

As close the range to the measured values, as small will the quantization error will be.

Please let me know, if I helped.

BR,

And where in that spec do you see that the device has anything except a +/- 10 volt range? Setting the min and max will do nothing if the card does not support it.
