OSFDPACL -EXP NO 9: Measurement of VSWR and Impedance PPT

Welcome to the Online Spoken Faculty Development Program on Advanced Communication Laboratory Organized by the Department of ECE, PSNA College of Engineering and Technology, Dindigul - 624622, Tamilnadu, India. In this video course instructor, Mr.R.Sathesh Raaj Assistant Professor/ECE elaborates Experiment No 9 - Measurement of VSWR and Impedance PPT. The voltage standing wave ratio (VSWR) is defined as the ratio between maximum voltage to the minimum voltage, this experiment deals with a waveguide slotted line to analyze the basic behavior of standing waves, and to measure the SWR, guide wavelength, and complex impedance. These slotted lines can be made with any type of transmission line (waveguide, coaxial cable, and microstrip), but in all cases, the electric field magnitude is measured along the line with a small probe antenna and diode detector. The diode operates in the square-law region, so its output voltage is proportional to power on the line. This experiment is used to study the waveguide components such as isolators, wavemeters, slide-screw tuners, detectors, and attenuators.
