PCM DECOMMUTATOR
 |
PCM Decommutator is realized on a PC to support data rates from 1 Kbps to 20 Mbps and interfaced through PCI, with a programmability of sync word, word length, No. of bits/word etc. The integrated system is built-in with windows application s/w, demodulator, bit-synchronizer and logs frame-synchronized data on to RAID with time tagging.
The system is monitored and controlled remotely through an Ethernet I/F & the real-time parameters can be monitored on the GUI. The system is also built-in with simulator for loop back test. Suitable for telemetry data handling applications.
