speeding up PXIe-4138 measurements

[Walid20]

I have modified an example VI to source voltage and continuously measure current from my PXIe-4138. However, it could only take about 4 measurements per second, which is not at the speed that I need. how can I make it measure faster. there are 2 channels because a I am sourcing another voltage simultaneously that is supposed to affect the current measurements.

Try stay in loop only measure VI and initialization out of loop.

I want to be able to change the applied voltage manually and observe the change dynamically.

For example. Is it suitable for solving the problem?

Thank you.

It worked for 2 channels as well
