Using six-port and eight-port junctions to measure active and passive circuit parameters
Cletus A. Hoer · 1975
This review paper brings together a number of old and new methods for measuring voltage, current, power, impedance, and phase angle using only amplitude type detectors.Vector voltmeters and ref lectometers can be constructed to measure all of these quantities in terms of four amplitude measurements made on four arms of a six-port junction.Where- as previous uses of this type of instrument depended on precision compo- nents for accuracy, new equations switch this dependence primarily to detector linearity and only secondarily on the properties of the measuring device itself.
