I am having two SMUs(4139 and 4140), how can I do the following?
There are three lines, say lin1, lin2, lin3.
1) I have to apply a voltage on lin1.
2) Start measuring voltage on lin2 and stop when it stabilizes on a particular level.
3) Once lin2 stops, start measuring voltage on lin3 and stop when it stabilizes on a particular level.
4) Find the time between when lin2 and lin3 stabilized.(I suppose this can be done by post processing. But just in case if there is any other direct way using NI SMU APIs, it could be better I believe).
Thanks in advance.

Why you can't read both channel at the same time?
Config-start-stop task need enough time, and this time is undefined.
Also you can try triggers.

I don't wanna read the channels at the same time. The thing is, the points I mentioned should happen at the same exact sequence.

Also how to take a series of measurements on a single channel without compromising on determinism.

You can't read only one channel at one time and do good measurements.
If some milliseconds (may be 5 or may by 50) is enough for you, you can read pbp and fix system time.
But if yuo need good preсision, you should read both channels and analyse 2D-array.
