tips on coding a voltage ramp with python

Question

I am new to python and trying to learn how to code a voltage ramp for a power supply. I want to ramp the output voltage from 0 to 10kv at a rate of 500v/s and monitor when the voltage breaks down through the sample (voltage goes to zero). Then i can record the max voltage before breakdown via an oscilloscope. Any ideas where to begin or a similar example that someone could point me toward?

Answer 1

Are you using some micro-controller?
If you can tell me what hardware/software you are trying to achieve this on, I think I might help you out.

Answer 2

Sure, I will be using a keithley 2280 low voltage power supply that connects to a power amplifier. This ramps voltage on my sample until breakdown. I will know when breakdown occurs when I get a negative edge trigger on my high voltage probe connected to a tektronix mso54. That should then kick the ramped voltage out of the loop and record the max voltage at breakdown. So this would use all the pyvisa commands to control the instruments.
