Multi-Function High Performance PCM Channel Analyzer

Toronto, Canada - GAO Instruments ( is offering a compact PCM channel analyzer designed to measure PCM devices, digital switches, carrier wave communication devices and VoIP devices as well as PCM voice encoding/decoding performance characteristics. The analyzer also measures return loss, longitudinal conversion loss and longitudinal conversion transfer loss. As it incorporates an analog signal generator/receiver, a selective level meter, a BER tester, a ring generator/identifier, a dialer, a DC loop circuit (ICT, OGT), a balanced bridge and a reflecting bridge into it, the channel analyzer is able to simultaneously measure more PCM channel characteristics than similar devices.

The easy-to-use PCM channel analyzer, model A0500033, features touch operation, key-stroke operation, expanded mouse operation, analog and digital interfaces, flexible control modes and a convenient GUI. Either equal step or customized frequency spots are selectable. Users can develop and design voice channel measurement and control systems under various conditions remotely via USB or Ethernet interface. The high performance PCM channel analyzer stores up to 100 groups of data, compares the measured results with built-in standard ITU-T tolerance masks and evaluates whether the results indicate passed or failed. Test results can be uploaded to a computer where they can be further viewed, analyzed, assembled, filed and printed via upgradable embedded software.
