Abstract:

A computer based system utilizing an inexpensive off-the-shelf personal computer and original interface design centered around a 68000 microprocessor for real-time monitoring of a time division multiplexed pulse code modulated TDMPCM data stream was designed and constructed. This system is a prototype of a low-cost, portable PCM data acquistion monitor intended for use in flight test programs by the 4950th Test Wing at Wright-Patterson AFB, Oh. It will accept a signle Armed Forces Instrumentation Standard NRZ or split-phase Manchester baseband data stream at rates up to 100 KBPS, display selected data words in graphical or numerical format, and alarm the user when data exceeds certain limits. It will provide a real-time verification that the data being generated and recorded during a test is of acceptable quality, allowing the option of continuation of the test, or termination. The system is capable of automatically determining the data rate and signaling format and synchronizing itself with the incoming signal. Keywords Pulse code modulation, Time division multiplexing, Data acquisition, and Microprocessor applications.
