Re: Low Power Output for Hendricks BitX20A - Watt meters and Scope readings do not agree.... #bitx20


 

The check would be you must be putting st least 2A into (24W to the finals, ~50% efficiency)
the finals to be in the 10-12W region.

I don't ever believe scope readings as accurate. For power out I use a dummy load with a
diode detector or a 30-40 db power attenuator as I have a calibrated unit 30db and 10db
that into the spectrum analyzer gives good reading for power.? If all else fails if my 10W
dummy gets hot its likely more than 10W.? The latter with a thermometer can be calibrated
for power equal temperature using a variable power supply (DC power=RMS power).

At some point you need an instrument you can believe.
