The Anritsu Site Master S820D is a portable, handheld broadband microwave cable and antenna analyzer designed for installation, verification, troubleshooting, and repair of radar and microwave communication systems. Operating from 25 MHz to 20 GHz (and extendable down to 2 MHz with Option 2), it employs patented Frequency Domain Reflectometry (FDR) technology and 1-port vector error correction to provide highly accurate return loss, VSWR, cable loss, and distance-to-fault measurements on both coaxial and waveguide systems.
