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.
Weighing only 3 kg, the Rohde & Schwarz ZVH is a handy instrument. Frequently used functions have their own function keys and are within fingertip reach. The built-in wizard lets users perform even extended test sequences fast and flawlessly. Using the R&S InstrumentView software, test reports can be generated in just a few simple operating steps.
The brilliant color display is easy to read even under poor lighting conditions, and it has a monochrome mode for extreme conditions.
The capacity of the R&S ZVH battery enables uninterrupted operation for up to 4.5 hours. The battery is changed within seconds. And if it rains? No problem – all connectors are splash-proof
KEY FACTS
• 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
