Ceyear 4957B RF Analyzer

With frequency range of 6.5GHz/18GHz/26.5GHz/40GHz, 4957B/D/E/F microwave analyzers integrate multiple functions such as dual-port vector network analysis, cable and antenna feeder test, vector voltage measurement, spectrum analysis (channel power, adjacent channel power, occupied bandwidth, interference analysis and frequency counting), field strength measurement and power measurement, providing you with powerful comprehensive test capabilities.

Dual-port vector network analysis can make comprehensive RF network parameters measurement quickly and accurately, providing logarithmic, linear, phase, group delay, impedance chart, polar coordinate, SWR and other display formats, and providing time domain measurement options.

Cable and antenna feeder test can measure the SWR, return loss, impedance, cable loss and other parameters of microwave networks such as antenna feeders, transmission lines and cables, and can  conveniently measure impedance discontinuity points in feeders and cables, with DTF function.

The vector voltage measurement function adopts an integrated solution instead of the traditional vector voltmeter to accurately test the electrical length of cables and some other devices under test.

Spectrum analysis is a spectrum analyzer with standard functions, which can measure the spectrum characteristics comprehensively in an electromagnetic environment.

The field strength measurement function has a friendly user interface and higher test sensitivity. With the corresponding test antenna, it can effectively monitor the electromagnetic spectrum and is widely used in space electromagnetic environment monitoring and radio management.

The USB power sensor is configured to achieve large dynamic range and high-precision power measurement, and can also carry out power monitoring through the spectrum input port.
