Abstract
A diagnostic data acquisition system for analyzing impairments in a QAM digital communication system is triggered by diagnostic data generated by a QAM demodulator when demodulating a QAM signal. Upon triggering, the data acquisition system can capture the diagnostic data used for triggering, and/or some other diagnostic data. The captured data may be stored for subsequent analysis to determine a probable cause of the impairment.
