The 3657 series vector network analyzer can be used in such fields as wireless communication, cable TV, education, and automotive electronics for measuring the performance of RF components such as filters, amplifiers, antennas, cables, and cable TV taps.
The product has such functions as error calibration, time domain, fixture simulator, automatic fixture removal, advanced time domain analysis, with many display formats such as logarithm magnitude, linear magnitude, standing wave, phase, group delay, Smith pie chart, polar coordinates, etc. for multi-channel and multi-window display, as well as many interfaces such as USB, LAN, HDMI and DP. It can quickly and accurately measure the amplitude, phase, and group delay characteristics of the S-parameter of the DUT, and has efficient and powerful error correction capability.
