Product Overview

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.

Typical Application 

4957B/D/E/F microwave analyzers are compact and portable. With many test parameters and 

comprehensive test functions, they are very suitable for multi-parameter test occasions, and can be 

battery-powered. As a powerful tool for field engineering installation, debugging, daily maintenance and 

repair of various microwave electronics, the testers can be widely used in various fields such as radar, 

communication, radio & television and radio management, and are also a good choice for teaching in 

colleges and universities. 

Test of main performance parameters of radar 

With full functions, 4957B/D/E/F analyzers can test the main performance parameters of radar antenna 

feeder, transmitting/receiving subsystem and other subsystems up to 6.5GHz/18GHz/26.5GHz/40GHz, 

including the SWR, reflectance, insertion loss, return loss and impedance characteristics of antenna 

feeder subsystem, the transmitting signal frequency and spectrum characteristics of transmitting 

subsystem, and the center frequency, gain, differential loss, bandwidth and dynamic range of receiving 

subsystem. 

Multi-parameter test in such fields as cable TV and wireless communication 

Cable TV, cellular telephone system, digital mobile communication operators and equipment 

manufacturers use 4957B/D/E/F testers to perform integrated test on spectrum distribution, antenna 

feeder contact performance, S parameters of components and parts and feedthrough power in the field.
