Power Meter shown measuring the output signal of a Rig Expert Analyser (-10dBm ) at 100mHz VSWR 1.08 indicates a nice 50 ohm input impedance. |
Connected to a home brew 40dB tap to allow higher power measurements, no signal noise floor is -74dBm…near enough for a backyard project. |
AD8307 power head, this assembly is enclosed in a brass screen to improve noise figures. |
