Rohde & Schwarz introduces 75-ohm network and spectrum analyzer

February 5, 2009

Rohde & Schwarz has introduced the R&S ZVL3 75, a single-box, 75-ohm network and spectrum analyzer in a compact, low-weight (15.4lb) form factor.

The R&S ZVL3 75’s 75-ohm connectors make the unit well-suited for development and production applications for TV, CATV and satellite TV components and systems. The R&S VL3 75, which features a frequency range from 9kHz to 3GHz, also can address measurement tasks during installation and maintenance.

The instrument is well-matched for passive component measurements, including determining the impedance of filters and cables. Other prime applications include standard amplifier and antenna matching measurements during system installations. The two-port bidirectional network analyzer enables complete system error correction. As a result, the unit can perform high-precision S-parameter measurements on 75-ohm DUTs. Battery-powered operation is available as an option.
