buffer and continous read written with correct time

[mischi_miyagi]

Hi,
at the moment I'm sourcing voltage and measuring current with a keithley 2400 sourcemeter (first a ramp up (with buffer read) then holding the voltage constant (with continuous read out), followed by a ramp down and again holding voltage constant), thus it is divided into four parts. ("Buffer read" in this case means storing data in instruments's buffer during sweep and read out all the data afterwards, "continuous read out" means I'm constantly sourcing voltage and take measurements seperately with a while loop.) My problem is now, that I cant get time-correlated measurement with charts since when I'm changing the voltage from a sweep to a constant value I'm sending data from/to measurement equipment, thus I'm not receiving data in this period. Also the read out delay is different for the constantly measured parts.
So, I'm queueing every part seperately and write it into one array together with the measured time between every part, meaning I'm queuing four different data parts, combine it into one array and write it into an xy-graph? Or is there an easier solution for this problem? I know it sounds a little bit complicated but maybe there's a easier solution...

Hello Mike,

I would like to help you but I can not understand your problem. I agree with you it sounds a little bit complicated.
Could you please explain your problem a little bit more? I think if you attach your Code this could be helpful to understand your issue.

Thanks

Hi,
actually I already solved the problem, but thanx for providing assistance anyway...
