Abstract : The Multi-Channel Communications System Analyzer (MCCSA) is a computer controller for a general communications test bed. The MCCSA consists of two or more PC AT style microcomputers, connected by a Local Area Network (LAN), off-the-shelf interfaces that permit connections to the test bed, a custom component called the High Speed Serial Data Comparator (HSSDC) to handle data channels up to 50 Mbps, and a combination of custom and off-the-shelf software that controls the experiment, aids in experiment definitions, and performs post-experiment analyses. The MCCSA is capable of injecting 50 Mbps test data streams onto the test bed, capturing two 50 Mbps data streams from the test bed, aligning the two captured streams, comparing them for discrepancies (errors), compressing the results of the comparison, and storing the results on magnetic media for later analyses. The MCCSA also supports a facility that permits it to respond (in real-time) to events happening on the test bed and to record the event (and its time of occurrence) for use in creating the post-experiment chronology and in analyzing the experiment. The MCCSA response to test bed events is user programmable and can serve as a basis for all types of open-loop/closed-loop experiments.
