Here some OEP-measurements:
Signals before & after TX look fine on scope.
However, I can't get the Ls & Rs measurements to agree with the D (1/Q)-indication on my LCR-meter,
so left those inductance measurements out for now.
Maybe we can solve that right here right now ?
It's about the measured DCR (not) being equal to the Rs following from
D = Rs / (2*pi*freq*Ls) = 1/Q
It goes fine for single inductors, but as said for a separate TX-winding
I can't get the measured DCR agreeing with Rs (for a series R & L equivalent circuit).
I must be overlooking something TX-related... :roll:
I know there can be some tricky things going on, but as said, the testsignal
as generated by the LCR-meter looks fine before & after the TX.
BTW, that signal is a on/off sinewave (say one second on, one second off)
with a swing of 1.5Vpp (unloaded).
