Re: A homemade diode power sensor for HP meters

Hi ,
it seems to me that q1 and q2 (FET) form an electronic key. then the capacitors must be there for the switch to work properly without switching aberrations. Already C7 and C8, possibly keep the input impedance controlled and prevent q1 (bjt) from oscillating.

You seem to have an extra diode, no terminator and reversed polarity. The terminator is probably the issue.
The 11863A calibrator manuals may give some clues too.
