VNA testing goes further
20 December 2010
Rohde & Schwarz UK supplies vector network analyser to test waveguide components to 500GHz.
Flann Microwave has acquired the 50 GHz R&S ZVA vector network analyser, and subsequently taken delivery of millimeter-wave converter heads that enable the company to test to 220GHz.
This represents the highest frequency test capability known within any UK commercial company to date.
Flann’s waveguide portfolio stretches from low frequency waveguides in the 1GHz range to high frequency devices in the 220GHz region and beyond. The latter are used by customers involved in microwave standardisation and also for the calibration of high frequency vector network analysers.
The vector network analyser from Rohde & Schwarz expands Flann Microwave’s test capability, facilitating the design, measurement and verification of the company’s range of waveguide components. With converter heads available to 500GHz, Rohde & Schwarz’ products enable Flann to respond to a growing demand for products and systems at higher frequencies, including VNA calibration and verification kits up to 500GHz.
Ian Crane, Chief Technical Officer at Flann Microwave, stated: “Expanding our test capability to 500GHz gives us a distinct commercial edge. We are already seeing enquiries for high frequency applications driven by news of our advanced test set-up.”
Steve Edwards, T&M Sales Manager at Rohde & Schwarz UK, added: “We are delighted to have been selected by Flann Microwave to help establish their high frequency test capability. The millimeter application area is an exciting growth opportunity for Rohde & Schwarz and we plan to continue to expand our product offerings at these frequencies.”
Among Flann Microwave’s key requirements were high dynamic range and the ability to provide continuous frequency coverage up to 220GHz and above. The R&S ZVA vector network analyser portfolio was designed to meet demanding measurement applications, including filter measurements requiring a high dynamic range. Their waveguide heads cover a wide frequency range, whilst the R&S ZVA vector network analyser gives customers the flexibility to operate it outside standard specified frequency ranges when necessary.
Jamie Lunn, Vector Network Analyser Product Manager at Rohde & Schwarz UK, commented: “The wide dynamic range of the R&S ZVA combined with low phase noise provides ample headroom for devices that would previously have been difficult to gain measurement insight into, such as Flann Microwave’s 500 GHz Rotary Vane Attenuator, which requires measurements to be made down to -100dB.”
