Configuring nRF5340 for RF measurements

How to configure nRF5340 for RF measurements. which programs can be flashed to the device to get 100% TX and 100% RX and measure the RF parameters

[runsiv]

Could you give some more information regarding the power meter? Normally we use spectrum analyzers to measure RF.

Hi Runar,

one doubt from my side, on current measurement I'm measuring both VDD & VDD_HV. Does current measured at  both this  points the same as the current consumed by the module/chip?

Hi, As you can see here it does not make sense to measure both VDD_HV and VDD."

By default, the high voltage regulator is configured to source external components from the VDD pin. To save power this feature must be disabled. For details, see High voltage mode."
Is the device running in HV mode? Also, is this a custom board? I'm not sure that you would gain anything to measure the current consumption since if it is a custom boards you it can be hard to correlate power consumption with RX effect.

Hi Runar,

What did you mean by custom mode I'm using a nRF5340 DK and putting it into modes like advertisement using nRF connect in V S Code. 

So my question here is at that time, which of these rails(VDD & VDD_HV) can give the chips current consumption at these modes.

I was supposed  to write custom board. Since you are using the DK we have guide for current measurement here. 

I would also suggest to upgrade to a newer version of NCS for doing the radio test sample. I'm not sure what is going on v2.3 but I have tested a few newer versions and they all build.
