The rapid expansion of mobile radio networks has required network operators to increase mobile radio antennas and base stations, often under strict time and cost constraints. The new R&S ZVH handheld analyzer from Rohde & Schwarz was designed especially to meet such demands. Two frequency ranges, from 100 kHz to 3.6 GHz or 8 GHz, are available.

Even in its basic configuration, the handheld analyzer detects cable faults, measures the matching of filters and amplifiers, and checks the loss of cable connections. For further measurements such as the isolation between transmit and receive antennas or the output power of output amplifiers, options are available.

The analyzer incorporates wizards that guide users through procedures in individual, well described steps. Network operators can adapt the wizards in the lab to their individual test report formats and make them available for use on site. Predefined test reports in various file formats make it easy to demonstrate that assignments were properly executed.

The fact that the R&S ZVH has a dynamic range of 100 dB means that it easily fulfils manufacturer's guidelines of >90 dB required for repeater measurements. The built-in DC bias supplies power to active DUTs, such as amplifiers, at both test ports via the RF cable.

The 194 × 300 × 69 mm instrument weighs 3 kg and frequently used functions have their own function keys. The color display is easy to read and there is a monochrome mode for extreme conditions. The capacity of the battery enables uninterrupted operation for up to 4.5 hours. The analyzers conform to protection class IP51 and feature splash-proof, dust-protected connectors.

The R&S ZVH comes with options for spectrum and network analysis and spectrogram display, which cover applications such as spectrum analysis, field strength measurements, signal monitoring and interference hunting. Using external power sensors, it can also operate as a power meter. When used with a directional power sensor, the analyzer can simultaneously measure antenna matching and transmitter output power up to 300 W.
