Test Unit Can Emulate Cable Network Impairments

Important enhancements have been made to the TAS 8250 Cable Network & Interference Emulator, claimed as the first product to emulate critical hybrid fiber/coax cable network impairments in a controllable laboratory environment. The new version provides advanced impairment generation capabilities for modeling complex HFC network characteristics and evaluating the performance of DOCSIS 1.1 cable modems and cable modem termination systems.
The unit also provides dynamic frequency allocation to model the frequency plans for different cable systems, allowing a variety of cable communications devices to be tested on the same unit. The emulator has added key channelized HFC network impairments, including bandlimited noise, QAM-16, QPSK, AM and CW interferers. The unit can be configured to emulate two different cable system frequency plans, one for the U.S. and another for Europe. Pricing starts at $59,950.
