PPK2 scope of usage

[elenva]

Hi,

Can we use the PPK2 kit for measuring current consumption in any other reference design board from a different

vendor which is not same as DA. The other vendor does provide probe point (GND, POSITIVE, and NEGATIVE) to connect

to PPK2 kit

Thanks,

Vijay

Hi Vijay

Indeed, the PPK2 is able to measure current on any external board (custom designs, nRF52 DKs, you name it) that is inside its specifications (It measures current from 500nA to 1A), and can give a detailed picture of the current profile for the user application.

Best regards,

Simon

Hi Simon, Can you help comment/analyse the power consumption of the two snapshots. The peaks are nearly same in both cases, but the lines are more densely/frequently occurring in one than the other.

Kind Regards,

Vijay

Hi Vijay

In this last snapshot it seems like the peak currents are all the same. Can you zoom in on multiple peaks and confirm or not whether all peaks are 716.80µA or not? If so, that points to the PPK not being set up correctly or not working correctly. Are you running it in Source Meter mode or Ampere Meter mode here, and how is it connected to the board you're measuring on?

Best regards,

Simon
