A Q meter is a piece of equipment used in the testing of radio frequency circuits. It has been largely replaced in professional laboratories by other types of Electrical impedance impedance measuring device, though it is still in use among radio amateurs.

Loughlin ref http www.hp.com hpinfo abouthp histnfacts museum earlyinstruments 0010 Boonton Q Meter Type 160 A, 1946 HP Virtual Museum ref . A Q meter measures Q, the quality factor of a circuit, which expresses how much energy is dissipated per cycle in a non ideal reactive circuit math Q 2 pi times frac mbox Peak Energy Stored mbox Energy dissipated per cycle . , math This expression applies to an RF and microwave filter , bandpass LC filter , or any resonator. It also can be applied to an inductor or capacitor at a chosen frequency. For inductors math Q frac X L R frac omega L R math Where math X L math is the reactance of the inductor, math L math is the inductance, math omega math is the angular frequency and math R math is the resistance of the inductor. The resistance math R math represents the loss in the inductor, mainly due to the resistance of the wire. For LC band pass circuits and filters math Q frac F BW math Where math F math is the resonant frequency center frequency and math BW math is the filter bandwidth. In a band pass filter using an RLC circuit LC resonant circuit , when the loss resistance of the inductor increases, its Q is reduced, and so the bandwidth of the filter is increased. In a coaxial cavity filter, there are no inductors and capacitors, but the cavity has an equivalent LC model with losses resistance and the Qfactor can be applied as well.
