GAOTek Portable CATV Signal Analyzer



This signal analyzer is specially designed and manufactured for CATV system installation and testing. It measures CATV TILT and trunk cable voltage accurately and also tests DVB-C digital signal features including average peak power, MER, BER, C/N, and EVM. Additionally, it provides constellation diagrams. This instrument tests CATV signal levels in both channel and frequency modes. In scan mode, the signal analyzer store signal levels for each channel. In spectrum mode, it provides spectrum display and tests for a certain frequency range.

Key Features

  • Tests CATV signal levels at both channel and frequency modes
  • High-speed measurement
  • Auto-off time setup
  • Auto scan testing
  • Portable, rugged and handheld design
  • Matrix super big LCD with back light
