Re: device support for Keithley 2450

Hi David,

To run a program when the source meter boots, name it "autoexec.tsp" on a USB stick (or that's how our works, anyway). You can see that this file does a lot, but has a very simple interface with K2612B_RadFET.proto. I should note that there is a bug in here somewhere. Changing settings sometimes crashes something, and I haven't had a chance to look into it.

Hi Garth,

   Thanks for responding. Yes, please, I'd like to take a look at what you have. I have a specific set of test measurements I want to automate, which sounds similar to what you did.

Thanks,

Pete.

I have a streamdevice based IOC talking to their similar 2612. My code wouldn't be directly useful to you, but depending on how you plan to use the 2450, the approach might suit you. They support a flavor of Lua with their own extensions that they call TSP. It was easy to learn. Console input/output from a TSP program can be used to write your own commands which interface with streamdevice. I used that interface for initialization and setting parameters. The TSP program executes a complicated series of measurements with timing requirements and 100+ data points, then sends the set of data back to streamdevice asynchronously.

On the other hand, if you want it for a general purpose lab instrument, this approach might not be flexible enough.

HI Tech-Talkers,

Does anyone have support for the Keithley 2450 SourceMeter?

THanks,

Pete.
