PPK measurements suddenly stops

[Pema]

Hi,

I am using the ppk II, and I have had a number of occasions where the current displayed on the PC suddenly disappears (see attached). The voltage to the DUT seems to be maintained though because the DUT continuous to function. First I thought that I had moved the USB cable and somehow created a disconnection from the computer, but since the supply to the DUT is maintained that can't be the case. Any suggestions?

Regards,

Peter

Hi Pema

Which operating System are you using?

What version of the Power Profiler App are you using?

Hi

A bug similar to what you describe was fixed in Power Profiler v3.1.3.

Try to update to the newest version.
If you experience the same problem again after this, please let us know.

Ok, I'll do that.

Hi again,

It seems like the problems have returned with nRF Connect for desktop 3.9.0/3.9.1, power profiler 3.2.0? The current trace freeces, and also disappears. I have to turn off the PPK and restart the profiler sw.
