While conducting an experiment you can use different techniques for measuring the signals. I was asked to code Keithley 2182A Nanovoltemeter in conjunction with 6221 DC and AC Current Source to perfom Pulse Delta and Delta measurements.
Before explaining the software part lets tackle a little bit of theory.
Delta voltage measurements use a current-reversal technique to cancel the effects of thermal EMFs in the voltmeter test lead connections. The simplest algorithm for a delta measurement uses the following 2-point source/measure process:
- Source a positive current through the DUT and measure the voltage (V1).
- Source a negative current through the DUT and measure the voltage (V2).
- Calculate the delta reading as follows:
