Keithley 2015 + RS232 = frequency response chart ?
« on: February 09, 2015, 08:21:29 pm »
Hi, I've finally got RS232-USB cable, 1.88$, 2x cheaper then one ride on a bus here in Sweden :scared: And I also have nice looking Keithley 2015. I've checked connection, it actually works, ":DATA?" do return me current data :-+

And I saw a lot of promo materials show nice graphs like this :


So, how one can do this graphs actually ? Is there a software to do it ? (I haven't found actual software from Keithley). Or should I just write little app with Qt ?

PS. Is there list of all available scpi commands for this device ?

Did you ever find an answer?  I'm looking at building something similar in Linux (maybe Sigrok does something already?) using python or something.

I know you can do it with things like Matlab, and almost certainly with LabView.

As long as you can capture data you should be able to chart it yourself. Python has tons of charting libraries.. https://lisacharlotterost.github.io/2016/05/17/one-chart-code/

There is an example of a logarithmic chart on that link, like the one you'd use for audio frequencies.
