The DS1151(B)/DS1185(B) Signal Level Meter is designed to provide features which are most widely used and favored by professionals in CATV industry at the least cost. Key functions include measuring and displaying the amplitude at a specific frequency or any carrier as defined by the user. In addition, the peak-hold level measurement feature in the LEVEL and SPECTRUM mode can even detect the occasional disturbance. Further, Analogue channels, Digital channels (QAM) and FM channels can all be tested efficiently and effectively with high accuracy rate. It also supports C/N measurement, voltmeter function, spectrum analysis, auto-test and data logging. Overall, its functions are easy to use and can be used in a wide range of applica-tions. As a result, its demand in the market has been consistently strong in the past. The letter "B" designation in the model type refers to its capability to provide a broader frequency range and support the return path measurement.
