The Power Profiler Kit II is an easy to use tool for power profiling all Nordic DKs, including the nRF9160 DK, in addition to custom HW. It can be used throughout all stages of the engineering process to speed up development of ultra low-power short range and cellular IoT applications.

Beautiful, this is exactly what I'm looking for and relatively at affordable price. Also it would be very nice if one of the IO pin can be configured as serial port, only RX pin will be enough. It will make the the measurement correlation even easier with readable text from serial along with the IO 0/1 state.

Hi Adam, that's a great suggestion. We've forwarded it to the team and they will have a look at it. Thank you.

This is a really nice tool, congrats to Nordic team! We've been developing a nRF5340 product since early engineering samples, and will be happy to use this. One question: does anyone here know what software suite was used to develop the graphic analysis tool? I'm tempted to guess Qt, but the speed at which the 100kps data set flows on screen is a bit too good for what I’ve seen on that platform.

They have public repository for the software: github.com/NordicSemiconductor/pc-nrfconnect-ppk It's JavaScript run in Electron (using Node.js)
@datenreisender
@datenreisender 3 роки тому
As @WisseSpring already wrote, we are using Electron and more concrete for the charts we are using Chart.js. www.chartjs.org But, yes, it is a lot of data to process, so we spend quite some effort to optimise handling that data to make the UI more responsive.

When using as an ammeter mode, am I correct to assume it would act as a multimeter/current meter? Where I could measure the inline current of a wire at any point of the circuit as long as the wires will be connected in series in Vin / Vout of the PPK2? I plan to measure and test a few signal currents coming in / out of an IC.
@NordicSemi
@NordicSemi Рік тому
Yes, it acts as an amperemeter (current meter) in ampmeter mode, and you can indeed plug it in series of the circuit you're measuring.
@losaminos59
@losaminos59 Рік тому
@@NordicSemi But do I still need to connect the ground pin of the PPK2? Unlike the traditional multimeter that is floating when measuring inline currents. I wonder what would happen if I left both the ground pins (left pin of Vin and right pin of Vout) not connected to anything? Something like this: Opamp output pin -- PPK2 Vin (ammeter mode) -- ESP32 ADC pin, to measure the incoming current to esp32.
@NordicSemi
@NordicSemi Рік тому
@@losaminos59 This will still work, but your measurements will loose some accuracy due to the fact that the PPK2 does not work exactly like a multimeter.

I have a question. Basically I would let PPK2 run for couple of minutes with a DUT connected to it. PPK2 provides 5V and DUT consumes about 60 mA. The results that I am receiving is in "REAL-TIME" window, however, after few minutes the application tends to freeze even though the power is still being delivered. I wonder if there is something that I should look out for in order to prevent this behavior? I could run more tests on different USB ports, different USB cable, even consider adding an additional one for more power (even though DUT only consumes 300 mW).

Hello, is it possible to connect PPK2 to other devices that are not From Nordic?

Yes, it is a standalone unit for power profiling and power optimization of embedded solutions. Power profiling and power optimization of embedded solutions. For more info: nordicsemi.com/ppk2

Does this tool will work with another (other than nRF) DK ?
@NordicSemi
@NordicSemi 3 місяці тому
Yes, the Power Profiler Kit II (PPK2) is a standalone unit, which can measure and optionally supply currents all the way from sub-uA and as high as 1A on all Nordic DKs, in addition to external hardware.

I have a question. Can i measure current consumption of 12v device? Im designing a product with 12v and buck converter i want to see how good my buck. I don't want to damage my unit so i have to ask before proceed
@NordicSemi
@NordicSemi Рік тому
We do not want you to damage your unit, so good you asked. The supported device under test (DUT) voltage for the PPK2 ranges from 0.8V to 5.0V. So no, you can not measure a 12V device. You can see the user guide for more details: infocenter.nordicsemi.com/topic/ug_ppk/UG/ppk/PPK_user_guide_Quick_start.html?cp=10_10_3

i have selected the ppk2 in the Power Profiler app, but it stills shows "instructions" and doesn't show any other buttons to do anything with the device. edit: I rebooted my computer and now they show up. (running Linux by the way, ofcourse I did install the udev rules)

This is really a current profiler, not power. Disappointing you cann't plot voltage beside the current trace. I needed to use this to look at a device running on battery and specifically device behavior when the battery gets low.

We are aware, and it is a feature we are considering adding in future firmware update for PPK2.
