source voltage measure current using Keithley 2400

[razii]

Hi

How would you make a simple automation test for a beginner to sourcing voltage of -50v to 2v in steep of .5v and measuring current with compliance current of less than 1A ( or 100mA) using Keithley 2400 and dump those result in excel or make a graph.

Thanks

First, download the drivers that are available.  You will want to initialize the insturment first and pass the VISA reference into a FOR loop.  Inside of this loop, you will set the voltage and then measure the current, autoindex the current levels to create an array of the measured currents.  For the levels to set, I would use the Ramp function and pass the levels into the FOR loop using autoindexing.  After the FOR loop, close down your instrument.  Wire up the graph to your array of currents.

the Ramp function have phase name and duration. I dont think I can use that funcation if I want my sourcemeter to automatically sweep from -50 to 2v in steps, and measure current for each one of those voltages.

Altenbach do you have any advice on this ?

You obviously are thinking of the wrong function. Use the search function for 'Ramp' and you'll see it does not have anything related to phase duration and duration. I have no idea what you are referring to.

Where do you see "phase" and "duration"? Ramp Pattern VI

Maybe the drivers have a ramp function also?
