quasi random signal sequence (QRSS)

Quasi Random Signal Sequence (QRSS) is a loading pattern applied in bit error rate tests( BERT) to determine the bit error rate( BER).

The stress pattern is based on a pseudorandom generator that generates all combinations of 20-bit words and continuously repeats these 1,048, 576 combinations. This stress pattern contains high density sequences, low density sequences, and those with strong and less strong changes. The QRSS pattern is the standard pattern for jitter measurements.
