Munich, March 2, 2010 - The high-end R&S ZVA67 vector network analyzer from Rohde & Schwarz is now also available as a four-port model. This is the first network analyzer on the market to feature four test ports for measurements up to 67 GHz. Its high dynamic range (110 dB at 67 GHz) and output power (6 dBm at 67 GHz) give the R&S ZVA67 the flexibility and performance required for characterizing components and modules in the microwave and millimeter-wave range. It allows users in research and development to determine the S parameters of multiport devices quickly and with high precision. As an extra benefit, the analyzer's four internal signal sources reduce test system complexity and the number of instruments required, e.g. for measuring frequency-converting DUTs, because no external signal generators are needed.

The new R&S ZVA67, with its unique architecture that includes four ports, four integrated signal sources and eight receivers, enables measurements on multiport devices such as mixers, couplers or balanced DUTs, with just one instrument. With its high output power of 6 dBm and wide power sweep range of > 40 dB, the R&S ZVA67 is able to characterize the small- and large-signal behavior of active components. Linear and nonlinear measurements can be carried out using a simple test setup. This advantage becomes apparent, for example, when measuring the S parameters or intermodulation of mixers or amplifiers, or when measuring the group delay and phase of up- or downconverters.

Offering a frequency range up to 67 GHz, the four-port R&S ZVA67 covers the band intended for the wireless transmission of multimedia data (wireless HDMI). Additional applications can be found in the aerospace and defense sectors, including measurements on inter-satellite communications systems and point-to-point communications systems. The analyzer's wide dynamic range of 110 dB at 67 GHz also makes it a valuable tool for material measurements or microwave imaging applications.

Frequency converters from Rohde & Schwarz extend the frequency range of the four-port network analyzer to beyond 325 GHz. Due to its outstanding performance, the R&S ZVA67 enables users to advance the development of materials and technologies into much higher frequency ranges.

The R&S ZVA67 in a two- or four-port configuration is now available from Rohde & Schwarz.
