Keysight Technologies Inc of Santa Rosa, CA, USA (which provides electronic measurement instruments, systems and related software used in the design, development, manufacture, installation, deployment and operation of electronic equipment) has collaborated with Virginia Diodes Inc (VDI, which makes test & measurement equipment for millimeter-wave and terahertz applications) to create a 1.5THz measurement solution for Chalmers University of Technology in Gothenburg, Sweden. Already up and running in Chalmers' national laboratory for terahertz characterization, the industry-first solution provides network and spectrum analysis capabilities for research on new materials, devices and circuits for applications at micro-, millimeter- and sub-millimeter-wave frequencies.
Chalmers' researchers are working in the terahertz gap between radio waves and infrared light. The measurement equipment from Keysight provides new capabilities that are enhancing their work with free-space, on-wafer and waveguide measurements in the terahertz gap.
The system is built around the Keysight's PNA-X microwave network analyzer, which covers 10MHz to 67GHz and reaches 1.5THz with external extension modules from VDI. Achieving an insightful understanding of device performance and behavior requires network and spectrum measurements, says Keysight, which claims that the PNA family is the first to provide integrated spectrum analysis capability that reaches into the terahertz range. The ability to access both capabilities in a single test setup — and make multiple measurements through one set of connections — saves time and enhances insight, it adds.
