RF Probe Calibration

The tests as shown were conducted between +27dBm and -3dBm. The results were not really conclusive showing some correlation between the probe and the Oscilloscope only at the two largest readings. The diode used in the probe was a mystery part and based on these measurements, presumably a silicon diode.

The next step will be to try some tests with greater power upto 5 watts and then to build a probe using a germanium diode such as a 1N34A.
