I would like to measure delivered power in a system with impedances that are signicificantly different from 50Ω (dominantly capacitive impedance with small real part) and with time variable load impedance. I think that the most accurate way is to measure Voltage and Current wave effextive values and phase difference between them and than calculate the power. I hope that I have a solution how to build the voltage probe, but I am not sure in which direction to go to pick up a current, since the current ranges from 0.1-200 A and working frequency is in range 1-20 MHz.
Is there anybody who has tried to use Rogowski coils in such applications?
Or someone has another idea how to inductively couple probe with the RF signal keeping the dynamic and phase response under control?
Any experience using bidirectional Wattmeter in such applications?
I appreciate any response.
Thanks,
D.
