Abstract :
This paper describes a modification to a conventional Q meter that permits direct measurement of Q in low-impedance tank circuits. The Q-meter voltage source was replaced by a wide-band current transformer operated in reverse, thereby lowering the instrument´s insertion resistance from 0.02 to 0.0002 ohm.
