Rohde and Schwarz has launched the R and S ZVH, a portable cable and antenna analyser that has been designed to facilitate the installation of antenna stations.

The analyser enables all in-field acceptance tests to be performed quickly and easily.

Wizards help users to measure antenna cables, filters and amplifiers, while simple tools generate test reports.

Using the R and S ZVH, installation teams can set up substantially more antenna stations than would be possible in the same amount of time using other commercially available test and measurement equipment, the company claims.

The R and S ZVH handheld analyser was designed to meet the requirement for network operators to set up more and more mobile radio antennas and base stations, as a result of demand for higher transmission rates in mobile radio networks.

Two frequency ranges, from 300kHz to 3.6 or 8GHz, are provided to help network operators, infrastructure manufacturers and their service providers to install and maintain mobile radio antennas with a minimum of effort and time.

Even users who have no experience with test and measurement equipment can, for example, check cable faults using the distance-to-fault (DTF) measurement or measure antenna matching and isolation.

Network operators can adapt the wizards in the lab to their individual test report formats and make them available to their service providers for use at the antenna site.

Predefined test reports in various file formats make it easy to demonstrate that assignments were properly executed.

The R and S ZVH speeds up acceptance testing, reduces training requirements and minimises the total cost of ownership.

It provides dynamic range of 100dB, fulfilling the manufacturer’s guidelines of more than 90dB required for repeater measurements.

The cost-effective handheld analyser replaces conventional test setups consisting of a signal generator and a spectrum analyser.

The built-in DC bias supplies power to active DUTs, such as amplifiers, at both test ports via the RF cable – especially useful for tower-mounted amplifiers (TMA).

The R and S ZVH measures 194 x 300 x 69mm and weighs 3kg.

Due to the upright format, all operating elements are at the operator’s fingertips, even when wearing work gloves, and without having to set down the instrument.

Since the R and S ZVH analysers conform to protection class IP51 and feature splash-proof, dust-protected connectors, they are reliable tools even under adverse ambient conditions.

When fully charged, the analyser can be operated for more than four hours on the battery alone and the battery can be replaced on-site.

It 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, the R and S ZVH can also operate as a power meter.

When used with a directional power sensor, the analyser can simultaneously measure antenna matching and transmitter output power up to 300W.
