VNA485 is a self-developed vector network analyzer with a frequency range of 300kHz to 8.5GHz. There are 2 ports and 4 ports for customers to choose. It is suitable for mobile communication, satellite, radar and other fields. It can complete accurate measurement for customers in the research and development and production of filters, antennas, circulators, isolators, amplifiers, switches and other radio frequency components.

 VNA485 has leading performance among the same type of instruments. Its dynamic range, measurement speed and trace noise are better than mainstream products in the market. Its high temperature stability, high calibration consistency and high reliability ensure long-term operation. Accurate measurement results.

 VNA485 has complete limit test, port extension, fixture simulation and other measurement and calibration functions, compatible with existing mainstream calibration parts and software interfaces, so that customers' existing calibration parts, equipment software, tools and matrix switches can be smoothly migrated
