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.

  • Handheld multifunctional microwave analyzer.
  • Multiple measurement modes:
    • Cable and antenna test (return loss, DTF, etc.).
    • Network analysis for test of full S-parameters (various display types).
    • Spectrum analysis (channel power, occupied bandwidth, etc.).
    • Power monitoring/measurement (optional).
    • Vector voltage measurement (optional).
    • USB power measurement (optional).
  • Frequency range:
    • Cable and antenna test: 1 MHz...20 GHz, frequency resolution 10 Hz.
    • Network analysis: 1 MHz...20 GHz, frequency resolution 10 Hz, dynamic range 80 dB...95 dB.
    • Spectrum analysis: 100 kHz...20 GHz, sideband noise -105 dBc/Hz at 1 MHz (1 GHz carrier).
  • Perfect auto diagnosis and auto status test.
  • Small, light and portbale, with built-in rechargeable battery.
  • Intelligent power management, indication of remaining capacity and low capacity alarm.
  • 7"/approx. 17.8 cm high-brightness true-color TFT LCD, good visibility even under direct sunlight.
  • USB 2.0 Host and Device interfaces, 100 M Ethernet/LAN network interface.


  • Test of filter specs like insertion loss, ripple wave, out-of-band rejection etc.
  • Measurement of time domain: Test cable length and DTF by cable and antenna test or time domain of network analysis.
  • Test of radar and communication system.
  • Monitoring and management of spectrum.
  • Monitoring of communication satellite.
  • Test of RFID and Bluetooth.
  • Test of components, parts and instruments.
