Hi, When discussing antenna analysers there's always a discussion on the issue of measuring the sign of X. For some years now I've carted round an article out of the Power Amplifier Handbook titled High-Speed Microprocessor Controlled Antenna Matching Unit, in which the author implemented a phase angle sensor which output a logic one for inductive phase angle and logic 0 for capacitive. The circuit didn't look like it was too complex to implement, so I've always wondered why such a circuit isn't implemented in every antenna analyser.
