[BC] FM Harmonic Measurements

[Bob Groome]

Nother shamless plug: the ERI directional couplers offer a great way to do these measurements. They are included with Master Antenna Systems so the intermod study can be done and checked when needed. They are available separately and you will find them packaged with the BDI power sense/measure systems.
