Abstract:
1. An emulator for modeling a plurality of signal impairments which manifest themselves onto a communication data signal between modulation and demodulation in a communication system, the emulator comprising: a plurality of programmable transmit modules emulating a plurality of signal impairments that occur during communication media modulation, each said transmit module having a signal input for coupling with a transmit modem, an output and a communication bus coupling; a plurality of programmable receive modules emulating a plurality of signal impairments that occur during communication media demodulation, each said receive module having a signal input, an output for coupling with a receive modem and a communication bus coupling; a user interface communicating with a processor for defining a communication system emulation by soft coupling a required number of said transmit and receive modules in a user defined arrangement; and said processor instructing each of said required modules via a communication bus to use specific signal impairments from said plurality of respective signal impairments for said user defined arrangement.
