Anritsu S820C – Site Master Microwave Transmission Line and Antenna Analyzer; 3.3 GHz to 20.0 GHz

The Anritsu S820C Site Master is a handheld microwave transmission line and antenna analyzer operating from 3.3 GHz to 20.0 GHz. It delivers vector error–corrected measurements of return loss, VSWR, cable loss, and distance-to-fault (DTF) with waveguide dispersion correction for accurate field diagnostics. The instrument locates transmission line faults using up to 517 data points and includes a fast tune mode with selectable resolution (65, 43, or 33 points) for efficient waveguide component adjustment.
