Sure, you can. The PPK II comes with two modes:

- inserted into the power path (usually VDD_supply - VDD_in)

- used as power supply

Which one is easier for you, depends on your device.

FMPOV, it's a great tool with an affordable price!

(With auto-zoom to selected range it may be easier to use, but even without, it works quite well.)

Yes, just follow the user guide for PPK II.

Hi Achim,

Based on your knowledge, can we use Power Profiler Kit to measure current for other boards apart from the DK kits.

Tks.

Just to say:

It may be not that easy to reproduce it. (Which, of course, is also a sign not to fix it ;-) ). If the developera want to fix it and need some log or similar information, let me know.

Sounds like a bug, I will report this internally.

That issue seems to depend on the used USB port!

I use the nRf9160-DK and the "Trace Collector V2 preview, v0.3.2" in parallel.

If is switch my USB ports of the PPK and the nRF9160-DK, the times are valid.

But if I switch them back, I the displayed time doesn't match.

Using Windows 10, the times are well ;-).
