S2188 Digital/Analog CATV Analysis Apparatus is a good kind of CATV.
Key Functions:
Analog channel measurementFull channel scanningSpectrum analysisDigital channel measurementInclination ratio measurementTrunk line voltage measurementFeatures of digital channel measurement:
The channel's average power of DVB-C digital cable TV (adjustable bandwidth), testing of MER modulate error, testing of BER error rate, testing of S/N signal-to-noise and supporting various DVB modulate modes: QPSK, 16, 32, 64, 128, 256QAM and COFDM. Features of analog channel measurement: Channel measurement, frequency measurement, spectrum analysis, inclination ratio measurement, V/A measurement, C/N, CSO, CTB measurement, AC measuremen
