摘要: The present invention provides a test device and method enabling automatic detection of an imbalance in power level digital channel. includes attenuator, tuner, demodulator, evaluation unit. According to the method, plurality channels are attenuated at attenuation levels, by means attenuator. A channel is selected from channels, tuner. modulation error ratio (MER) measured demodulator. variation MER with then evaluated, unit, detect
