There are lots of potential problems with your code.
- As a first step, take the instrument initialization (both K700 and B2900) outside of the FOR loop. You should not be re-intializing every itteration, it appears you simply want to change some switch parameters and biases. You aren't closing communications in the loop, so trying to re-establish a link might be the issue. If you are using the INIT vis to reset the instrument, don't. Simply issue the reset command, and make sure the timeout for that instrument is appropriately long so it doesn't return an error.
- After sending a string of commands to B2900, and before executing a measurement, check for errors and handle the errors.
- For some reason your channel controls are v16 when i32 is expected. That shouldn't cause an issue, but its good to look at the red coersion dots to see if some input is in a format the subvi is not equipped to handle.
- It would be good practice to make a subvi for the B2900 measurement setup, that would make your code easier to read. Bundle all the settings that are now inside the loop and feed to a subvi and unbundle as needed. It looks like all those settings are not changed within the loop anyway.
I suggest making the changes to the for loop then running this in Highlight execution and specify where the error occurs. Narrow it down and perhaps it will be obvious.
Hope that helps.
