Abstract
A test set used for introducing a Poisson distribution of errors into a known digital data signal to produce a test signal uses an error signal generator that produces a Poisson distribution error signal. The error signal is then combined with the known digital data signal to produce a test signal with the Poisson distribution of errors. A pseudo-random binary sequence generator is used to produce a PRBS sequence and a comparator is used for comparing the PRBS sequence with a probability control signal. The comparator sets a single bit in the output stream of zeros when the PRBS sequence is less than the probability control signal. For multiple bit Poisson distribution error signals the PRBS generator and comparator combination may be replicated m times, or a single PRBS generator may be used and a unique independent subset of the PRBS sequence is applied to each of the multiple comparators.
