Ceyear AV4958

Multifunctional Microwave Analyzer

AV4958 Multifunctional Microwave Analyzer integrates multiple functions, such as tests of cable and antenna SWR, distance to fault(DTF), insertion loss and gain, spectrum analysis and power measurement, etc.. It is flexible and convenient to carry with the frequency range from 1MHz to 20GHz. Battery is available for power supply, 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. The analyzer can help upgrade filed repair and support of users.


  • Multiple measurement modes:
  • Cable & Antenna test: for test of cable and antenna (return loss, DTF, etc.);
