Hello,
I’m currently working with a custom board based on the nRF9160 SiP, and I would like to measure the LTE-M TX power after the antenna impedance matching circuit. Ideally, I’d like to perform this measurement using an nRF9160 DK to help automate the RF testing process.
I’m aware that the %RFTEST TX AT command provides the transmitted power, but this measurement is taken at the antenna output, not after the matching circuit.
I was considering using the %RFTEST RX command on the development kit to capture the transmitted signal from the custom board. However, from my understanding, direct communication between two nRF9160 devices in this context is not supported.
Is there a recommended way to measure the TX power after the impedance matching circuit using a development kit, or any other method you suggest for automating this measurement?
Thank you in advance for your help!
Best regards,
