ZVH

A handy analyzer for installation and maintenance in the field; easy operation and simple documentation

The R&S®ZVH is a rugged, handy cable and antenna analyzer, designed for use in the field. Its low weight and simple operation make it indispensable for anyone who needs an efficient measuring instrument outdoors for the installation and maintenance of antenna systems. When it comes to the installation or maintenance of antenna systems for mobile radio, broadcasting or radiocommunications, the R&S®ZVH cable and antenna analyzer performs fast, reliable and highly accurate measurements. Even in its basic configuration, the R&S®ZVH detects cable faults, measures the matching of filters and amplifiers and checks the loss of cable connections – the three most important tasks involved in setting up transmitter systems and putting them into operation. For further measurements such as the isolation between transmit and receive antennas or the output power of output amplifiers, suitable options are available to the RF service engineer or maintenance team.

Features

• Frequency range from 100 kHz to 3.6 GHz or 8 GHz
• 100 dB (typ.) dynamic range for filter and antenna isolation measurements
• Factory calibration over entire frequency range
• Built-in DC voltage supply (bias) for active components such as amplifiers
• Power meter option
• Saving of measurement results on SD memory card or USB memory stick
• Easy operation with user-configurable test sequences (wizard)
• Easy-to-replace Lithium-ion battery for up to 4.5 h of operation
• Rugged, splash-proof housing for rough work in the field
• Easy handling due to low weight (3 kg with battery) and easy-to-reach function keys
