Oscilloscope TDS 3014 - Ethernet - Labview : work only in debug mode

[fabbro12]

Dear all,

I want to control an oscilloscope from Tektronix, TDS 3014B, connected through ethernet cable, with a labview software. I thought it was an easy task as I have downloaded special VIs for this intrument here:

I did my own code using the VI provided and I attach here my VI.

The problem is that the output array is always wrong! But when I go to debug mode to see what's happening wrong, the software starts working properly and measuring correctly. I give as input a 5Vdc to the oscilloscope probe, and the 5V are measured correctly in debug mode but in normal mode I measure -10V.

Anyone had the same problem? 

Thanks for assistance

What happens might be that in 'debug' mode, more time elapse between your autoset and the rest of the code.

Maybe you can try to add a delay (use 'wait ms' function in a flat sequence structure, make the error wire go through the frame to force the dataflow to wait ; try waiting 5000ms at first) between the autoset and the read waveform function.

Does it help ?

Thanks!

It's working now...
