Directivity and VSWR Measurements - Understanding Return Loss MeasurementsDoug JorgesenChristopher Marki
Measuring the quality of the impedance match of a test device (VSWR or Return Loss), requires separation of the incident signal from the reflected signal. Separation of the two signals is performed by directional devices and the accuracy of the measurement is determined by the directivity of the...
It is quite important, however, that the terminating impedance at the common or S-port be very accurate. Deviations from the correct impedance value will cause significant errors. Typically, a termination impedance with a VSWR of 1.05 to 1 is used at Mini-Circuits for isolation testing. How t...
The article focuses on the standing wave ratio (SWR) or voltage standing wave ratio (VSWR) used in discussions or arguments among the technicians. It has been stressed that the transmission line loss may impact the calculations. It was found out that the forward and the reflected waves will ...
