The current probe is a A6302 from Tektronix driven by an AM 503B controller, it goes from DC to 50Mhz.
I zero out the probe before doing a measurement, but it does show some offset in the measurements, but this offset seems to not influence the power calculations.
Anyway, i did redo these tests and got similar results, but i also noticed that measurements this way are not good. My FG is grounded and also my scope is, so these grounds have a hugh impact on the measurements, especially on the 1K load ones somehow.
My battery operated FG's do not go beyond 5Mhz, so no good for these tests.
Guess i leave it at that.
