Radio test plan
Find below all the measurements which have to be done by test sequences.
M
When using a wired test solution (via RF cable), don't forget that it is mandatory to measure the power level
radiated by the antenna (powermeter recommended). It is the only way to ensure good contact between
antenna and main board.
This warning doesn't apply when using an antenna coupler.
