GAOTek Portable High Performance Spectrum Analyzer

This handheld, lightweight Spectrum Analyzer is designed to locate, analyse and map the signal interference and is very useful for wireless communication field engineers to characterize the signal environment.





GAOTek High Performance Spectrum Analyzer combines the functionalities of 100 kHz to 3 GHz spectrum analyser, wireless communication signal power tester, interference signal analyzer and RF signal analyzer. The wireless spectrum is shared among different communication systems like mobile communications and mobile radios and in addition to licensed systems, the spectrum is also shared with unlicensed transmitters and signal impairments such as reflections and fading. The combination of all these signals creates a very complex environment which must be first cleared and routinely monitored in order to maximize service performance. These Spectrum Analyzers are used to accurately characterize the signal environment in addition to clearing, detecting, identifying and locating signal interference.


  • Quickly identifies, locates and maps signal interference.
  • Performs comprehensive signal analysis for complete site profile and monitoring of signal environment.
  • Occupied Bandwidth, Channel Power and ACPR.
  • Dual spectrum and spectrogram measurements.
  • Verify RF transmission.
  • Handheld, lightweight, rugged design that withstands harsh environments and lighting conditions.
  • Intuitive menu structure enables ease of use and quick measurements.
