The 3776B PCM Terminal Test Set interfaces directly at the analog and digital level in mixed analog/digital networks. This unit is suitable for North American/Japanese/CCITT networks. Used in installation, commissioning and maintenance, the 3776B ensures optimum performance for each section (e.g., PCM channel bank, digital switching system or transmultiplexer) of the network. The 3776B provides comprehensive voice, PCM and data measurements for testing 4 kHz bandwidth analog and digital channels. It replaces the collection of independent analog and digital test equipment previously used in a mixed system environment with one compact instrument. Features include: Pre-programmed default measurement parameters. User-modified measurement parameters held in non-volatile memory. Measurement sequences can be downloaded from a controller to the 3776B and run independently. Manufacturer’s Options Option 001 = Data measurements methods conform to IEEE STD 743 – 1984
