VNA5000A is a high-performance vector network analyzer that provides multiple calibration methods such as single-port, response isolation, enhanced response, and full dual-port. Built-in multiple display formats such as logarithmic amplitude, linear amplitude, standing wave, phase, group delay, Smith chart, polar coordinates, etc. Equipped with various standard inputs and outputs such as USB, LAN, GPIB, VGA, etc. It has all the measurement functions of a traditional vector network analyzer and can accurately measure the amplitude-frequency, phase-frequency and group delay of microwave networks.
