What are you trying to measure, the fundamental, modulation, harmonics or what? #this will determine what bandwidth and accuracy you need
Is the measurement off-air or into a dummy load. If a load a power attenuator is best. if off-air some kind of coupler will be required. a resistive tap like
? or
would do and is reasonably broad band.
If looking at harmonics you will probably have to put a notch filter in the sampled ignal to reduce the carrier level and prevent spurious signals being generated in th analyser.
