The S820E represents the most advanced generation in the Site Master family, delivering microwave test capabilities typically reserved for benchtop VNAs, now in a field-deployable handheld unit. It's engineered to support coaxial and waveguide systems across industries including aerospace, defense, radar, broadcasting, and 5G.
With VNA mode, users can perform 4 S-parameter measurements simultaneously using a quad-display layout. The analyzer supports .S2P file generation, making it compatible with lab VNAs like VectorStar™ and ShockLine™. For legacy replacement needs, the VVM mode offers drop-in compatibility with older Vector Voltmeters, including ratio measurements and absolute transmission/reflection tests.
The VIP Mode adds fiber inspection capability to RF sweep tests, creating a true all-in-one diagnostic tool. A single USB cable powers remote USB sensors, enabling swept cable loss measurements up to 85 meters apart, ideal for tower-top to base testing.
The S820E is designed with field operability in mind—offering Classic Mode UI, a built-in help menu, and seamless file export. With advanced test features and future upgradeability, it is a long-term investment for serious RF professionals.
