Hi there,
I would like to implement to measure very small voltage. So, I need to measure voltage in the order of 0.5 mV and 5mV (the current of the system will be in the order of the 5A to 50 A) , with a resolution of 0.05 μV to 0.5 μV. Is there any national instrument euipment that can help me to do this?, Alternatively, I will work with a nanovoltmeter model 2182A. However, I am in the same situation, because, I want to register the data in my computer using a ni usb 6009 (In theory, this equipment does not have enough resolution), Maybe, I need an amplifier in the middle. Please, Could you suggest me a DAQ for doing this job?
Regards.
