Keysight B2901 (B2900 series) shuts off source after initiate command

[Tobias_491]

Hi everyone,

I want to programm a power meter with the Keysight B2901.

Therefore I want to measure a defined number of current and voltage values in a defined time interval.

The program executes with no errors but the source shuts off after the initiate.vi 

Does anyone else have this kind of behaviour?

The single measurement example worked for me without any issues but is too slow for my application.

Best regards

Tobi

Without being able to see the front panel  (attach your VI with default values save, not a screen shot) values you used for the measurement, I'll make a few guesses.  Other useful info would be..

What do you have connected? 

How much current flow are you expecting? 

- The compliance current is too low, default on block diagram says 100uA. If compliance is tripped the Output will turn off, unless you set it otherwise.

- The input to your Trigger VI has a comma "," in it.  Make sure this isn't causing an error. If ther's an error then Ouput VI never gets executed an output never goes ON.

Hope that helps give you a few things to look at.

This is a problem ONLY for strings, not for (DBL) floats.

(Hopefully the driver handles OS-dependent regional settings correctly - I have seen too many drivers, that did not…)
