描述

The VNA485E is a 100 kHz to 8.5 GHz vector network analyzer available in 2-port and 4-port configurations. Its dynamic range, measurement speed and trace noise outperform comparable instruments, while high temperature stability, calibration consistency and reliability deliver precise results over long-term operation.

Complete limit test, port extension and fixture simulation functions, compatibility with mainstream mechanical and electronic calibration kits, and VISA/SCPI interfaces allow existing calibration kits, software, tools and matrix switches to migrate smoothly. The integrated 10.4-inch touchscreen with familiar key and menu design makes daily operation effortless.
