GAO Tek Updates DS1151 (B) Super Signal Level Meter

GAO Tek Inc. is introducing an upgrade to its DS1151 (B) Signal Level Meter. The newly developed model, DS1151 (B) Super Signal Level Meter, is designed to provide features which are most widely used and favored by professionals in the CATV industry. Key functions include measuring and displaying the amplitude at a predefined frequency or carrier. In addition, the peak-hold level measurement feature in LEVEL and SPECTRUM mode can even detect the occasional disturbance. Analogue channels, digital channels (QAM) and FM channels can all be tested efficiently and accurately. The device also supports C/N measurement, voltmeter functions, spectrum analysis, auto test and data logging. Overall, it is easy to use for a wide range of applications. As a result, market demand has been strong. The letter ‘B’ in the product designation refers to its capability to provide a broader frequency range and support the return path measurement.
