SMU vs. DAQ

Solved!
Go to solution

Hello to everyone, 

thanks in advance for all you can suggest to me.

I am wondering about the purchase of 2 SMUs vs. DAQ.

What is the real advantages of using a SMU instead of a multifunction data acquisition ?

(I have seen for example the NI X series Multifunction data acquisition systems).

They are two completely different types of equipment.  An SMU is a Source Measuring Unit.  You can think of it as a very precise power supply.  A DAQ is a Data Acquisition.  It only reads voltage, usually in many channels at a time.

 

So the real question is what are you trying to do?

The problem you might have with the analog outputs of a DAQ is that they have a really small current limit.  I would use 2 SMUs for my input and a DMM to measure the output.  I am sure you can find an SMU with a lot lower voltage range.  Just a quick look and I see a PXIe-4144, which has 4 outputs at 6V, 500mA.  So I would go with that and a PXIe-4081 DMM.
