Rohde & Schwarz Launches New Generation Antenna Tester

Rohde & Schwarz announced the ZVH, a new handheld antenna line analyzer at the 2010 Electronica in Munich. ZVH is specially designed for the installation of antenna feeders of base stations or transmission towers. It can quickly and easily complete the acceptance test of the field. ZVH's unique wizard function can help users easily complete antenna, cable, filter and amplifier testing. Users can easily generate test reports using document functions. Compared to other instruments, ZVH can save the user the test time, which can complete the installation of more base stations.

The rapidly developing mobile communications network provides users with seamless coverage and high-speed data transmission rates. This also means that operators must build more antennas and launch pads with limited funds and time. R&S's next-generation handheld antenna line tester ZVH is designed to solve this problem. ZVH is available in two models with frequency ranges from 300kHz to 3.6GHz or 8GHz. ZVH can help operators or service providers to complete the construction and maintenance of mobile communication networks with minimum time and effort.

ZVH is the only antenna feeder analyzer in the industry that supports the test wizard function. The test wizard is convenient and easy to use, even those who have no experience in the use of test instruments can quickly get started, for example, can easily complete the cable dead point test or antenna matching performance and isolation. Because the test error caused by the wrong setting will become history, the operator can set the parameters of the test wizard and the format of the test report in advance in the laboratory, so that for the service provider, the test task and test settings are clear, and only need to call. The preset test wizard can easily complete the test task. Therefore, ZVH can greatly accelerate the acceptance test and greatly shorten the training time, saving time and cost for customers.

ZVH has the best RF index in its class. It is the only antenna feeder analyzer with dynamic range up to 100dB in the industry. It can fully meet the dynamic range requirements (greater than 90dB) in repeater testing, so customers no longer need to Use expensive and inconvenient signal source and spectrum analyzer solutions. ZVH has built-in DC bias, so it can supply power to active DUTs, such as amplifiers. The ZVH can be powered through any RF port, which is especially suitable for tower amplifier testing.

ZVH is small and light (only 3kg, 194mm × 300mm × 69mm) easy to use. Many functions (such as a test wizard) can be completed with just a few keystrokes. Even with a working glove, it does not affect the operation of the instrument. ZVH meets IP51 protection level, splash-proof and dust-proof, and can work normally even in harsh environments. ZVH can be used for 4 hours after it is fully charged. If you need longer battery life, simply open the side cover to replace the battery.

ZVH is also a wise choice for long-term investment: ZVH can be upgraded to spectrum, vector network analysis and spectrum waterfall functions, so ZVH can also perform spectrum analysis, field strength measurement, signal monitoring and interference search functions. The ZVH can also be used as a power meter if an external power probe is fitted. If connected to the FSH-Z44 pass-through power probe, the ZVH can measure up to 300W of transmitter output power while measuring antenna-line matching performance.

Users can now order a new generation of Antenna Line Analyzer ZVH4/8 from R&S.
