Ceyear 4958 Handheld Multifunctional Microwave Analyzer
The Ceyear 4958 multifunctional microwave analyzer integrates multiple functions, such as tests of cable and antenna SWR (standing-wave ration), DTF (distance to fault), insertion loss and gain, spectrum analysis and power measurement. It is flexible and convenient to carry and has a frequency range from 1 MHz to 20 GHz. The 4958 can be battery-powered which makes it suitable for field tests. Used widely in several fields including field installation, performance test, daily maintenance and emergency maintenance test of electronic equipment in terms of radar, communication and ECM.
