Measure nrf Current consumption using an Oscilloscope

[carvalhn]

Hi,

I need to measure the current consumption for nrf51DK using an Oscilloscope. I have read the user guide and they have mentioned some connectors for it. Is it possible to just measure the current consumption using an Oscilloscope and if yes, then could you please let me know how to do the same?

Thanks a lot in advance.

Hello,

have you read the nRF51 DK Guide? It is pretty much all explained there.

First Paragraph is about measuring with a multimeter, next paragraph explains measurements with an oscilloscope.

First, cut the Solder bridge, afterwards you need to attach a resistor with 10 ohm for example on the two solder pads right next to the bridge, then you use your oscilloscope, connect both thingys (forgot what their called) to ground and the measuring tips to the two current measurement pins, just as shown in the guide. Now I've used the mathematics operations on my oscilloscope to substract the two signals and then you're ready to go.

Did you check the voltage of your battery?
