What NI DAQ device or system can receive signals nanovolts?

We have an analog sensor here that its production gives us nanovolts control signal. I was wondering is there any device NI DAQ, you could introduce me so that I can take these steps for the Labview? (signal to noise ratio is low) It would be great if you also offer me an Osciloscope code or software in Labview that get the signal of the DAQ hardware and I can play with, or record the signal as a real Osclloscope because I couldn't find a good in the examples. If this question is not linked here please provide a link for me to remove this item and it ask for more in the forume somewehere. Thank you

nV is not much so some requirements more are needed:

need resolution?

need for precision?

bandwidth of the signal?

the source impedance (or current bias data acquisition acceptable entry?)

Value of Absolut or changes in the amplitude?  (important for the specification of the drift)

I would go with a preamplifier or ask Keithley NI sorry

A good source of information to measure really tiny values is the "low level measurements Handbook" of keithley...

Sorry, no link to it... These % $§ ' engine % of research do not provide direct plus links
