Hi all,
I'm trying to measure the transmit power of nRF51 development kit with a spectrum analyzer and I am facing the following issue:
It is specified in the user guide of nRF51 that "When connecting the test probe, the internal switch in the SWF connector will disconnect the PCB antenna". However, in my case, I can still connect to the nRF51 with my phone, while an SWF connector is plugged in the board. I suppose that the trace antenna is still connected. My connection setup is like in this answer.
I was assuming that any SWF connector should work but is the one from Murata specified in the user guide the only one able to achieve this ? If not, do you have any more guidance ?
Thanks in advance
