CATV Meters & Instruments

GAOTek offers high quality, affordable CATV meters and testers to industry engineers. These instruments are used by professionals to automatically or manually test, measure, and maintain a wide collection of systems and channels. Our products are portable and durable to ensure long operational use during everyday field use by CATV technicians. Additionally, we offer QAM analyzers, PCM channel analyzers and TDR cable fault locators.


QAM and PCM analyzers are portable handheld devices that analyze QAM and PCM signals, and measure digital channels and devices, analog channels, digital switchers, and FM channels. They can be used for performing tests automatically/manually and comparing results.


Signal level meters (TV and CATV) are designed for CATV installation systems to measure analog and digital channels and testing CATV signal levels in channel and frequency modes. Moreover, these devices maintain CATV systems, and construct analog TV/ digital TV signals.


Cable fault locators are devices that locate and analyze cable fault points such as short circuits, open circuits, impedance break points, and high resistance points. These devices are paired up with time domain reflectometer (TDR), and are widely used for cable test, cable maintenance, and cable installation by professionals.
