Lyles" <jtml@lanl.gov>; Date: Fri, 7 Jan 2005 13:52:21 -0700; The Q meters that use resonance of a component against a known standard capacitor or inductor are not so useful to measure unloaded Q of a tank circuit. I am referring to the old Hp and Boonton Q met; /archives//html/Amps/2005-01/msg00103.html (7,620 bytes)

8. Re: [Amps] Q meter [TSPA] (score: 1): Author: G3rzp@aol.com; Date: Sun, 9 Jan 2005 02:57:34 EST; There's a question as whether the Q function on an LCR meter measures Q - or rather, which Q it measures......
