Re: Using 2651A at Higher DC current

Hi Jerry,
You can parallel 2x2651A to meet your requirements. In TSP Express (built in software), there's an option for you to combine the SMU.

It is a Download Java Runtime J2SE(TM) Environment.

Re: Keithley 2400 surge current

Hello,
There's a possibility that during your power up cycle/sequence of the instrument a transient happens, which could be higher than 0.1V. Is there a way to debug your test(s) using a scope maybe to see whether there's a spike going on?

Re: 2612 incorrectly measuring current under 1mA range

Check the response after the unit is back from repair if the range change during the 1000 pts sweep has some effect assuming you use autorange with reasonable delay between points.

Hello, You are correct. The design of 8009 test fixture is different than an AC or two port type of measurement. The interconnect/cabling are totally different between CV and IV application. I am not sure why you wanted to use the 8009. Why not use a probe? With our 4200-SCS parameter analyzer, you ...
