MMWAVE-STUDIO: how to measure the TX power of IWR6843 at single frequency?

for the RF performance test including an antenna performance

i would like to measure the TX power from the IWR6843 Radar board at single frequency

for example measuring the output power at 60GHz, 61GHz, 62Ghz, 63GHz, 64Ghz.
