USB Vector Network Analyser (uVNA)

The uVNA provides accurate and sophisticated network analysis measurements of antennas and electronic circuits at low cost.  It finds application in radar site support; in electronics design, development and test activities; and in electronics teaching environments.

In radar systems, evaluating and optimising the performance of antennas and antenna arrays are fundamental requirements and a vector network analyser is an indispensible tool in the development, commissioning and maintenance of radar installations.

In electronics laboratories, the vector network analyser finds wide application in design, development and test measurements, and in fault finding and repair of electronic equipment.

The uVNA is a 2-port instrument to provide both reflection and transmission measurement capability. It is a calibratable instrument and applies the standard short, open, load calibration procedure.

Traditional portable and benchtop vector network analysers are highly sophisticated instruments that come at a commensurate high cost. Standalone portable instruments still tend to be bulky and weighty whereas the USB VNA is very small and lightweight and makes use of the ubiquitous laptop computer to provide control, processing, measurements display and storage functionality. In this way, it becomes an economical reality to broadly equip field stations, electronics development and test laboratories and teaching facilities with this powerful and sophisticated circuit analysis tool.
