Product Description


This advanced portable PCM channel analyzer integrates an analog signal generator/receiver, a selective level meter, a BERT, a signaling generator/receiver, a ring generator/identifier, a Dialer, a DC loop circuit (ICT, OGT), a balanced bridge and a reflecting bridge and other functions into a single instrument. It has functions for measuring PCM voice encoding and decoding performance characteristics and is widely used to measure PCM devices, digital switches, carrier wave communication devices and VoIP devices. With remote control via USB or Ethernet interface, users can develop and design voice channel measurement/control systems under a variety of different conditions. The analyzer also compares the measured results with built-in standard ITU-T tolerance masks to evaluate whether the results indicate a pass or fail. Test results can be uploaded to a computer where they can be further viewed, analyzed, assembled, filed and printed via the included software.

Key Features
