Munich, Germany The ZVT8 from Rohde & Schwarz is claimed to be the world's first eight-port vector network analyzer up to 8 GHz for universal measurements on multiports and balanced DUTs. Featuring true multiport architecture, the instrument offers very short measurement times while maintaining high measurement accuracy and a wide dynamic range. Its excellent specifications, high measurement and data transfer speed and versatile remote control options make it an ideal choice for sophisticated tasks in the development and production of multiport components. The network analyzer is equipped with a measurement receiver and a reference receiver at each of its eight test ports. It can thus perform measurements at all ports of a multiport component simultaneously. This yields very short measurement times plus a wide dynamic range and high measurement accuracy, especially as compared with network analyzer systems based on switching matrices. With its multigenerator concept featuring several internal generators, the ZVT8 not only performs fast measurements on multiports and balanced DUTs but can also measure several DUTs simultaneously. It features a wide dynamic range of more than 120 dB, a maximum output power of higher than 13 dBmat all test ports, and an electronic level sweep range of 50 dB. Its modern Windows-based user interface includes wizards for complex measurement tasks and is operated via an external monitor using a mouse and keyboard. Up to 20,001 points per trace can be selected, and a virtually unlimited number of diagrams, channels and traces is available. The direct generator/receiver access option provides direct access to all 16 receiver and eight generator paths. Moreover, this option even further increases the high output level and sensitivity of the base unit. The time domain option enables, among other things, the elimination of discontinuities. The ZVT8 also offers state-of-the-art calibration techniques, allowing calibration to be performed directly on wafer structures, for example.
