In this video, how to measure unknown impedance was explainedAn Overview of the Slotted Line Impedance Measurement TechniqueSLOTTED LINE MEASUREMENTS Objective: To familiarize with the measurement technique using slotted line. a) Measurement of standing wave distribution on a slotted line, with short circuit and open circuit termination. b) Measurement of guide wavelength and determination of operating frequency. c) Measurement of high VSWR by double .
The most common sources of uncertainty are from the residual VSWR, probe effects and line losses. This residual VSWR is a result of discontinuities generated by variations in characteristics impedance, slot effects and the flanges on the end of slotted line. It can be measured using the quarter-wavelength and sliding load techniques.
