Agilent Error Performance Analyzer
The HP 70843A Network performance analyzer, is capable of generating PRBS, zero substitution, variable mark density, as well as user-programmable test patterns. In zero substitution test patterns, zeros can be substituted for data to extend the longest run of zeros in patterns. The longest run can be extended to the pattern length -1. The bit following the substituted zeros is set to 1. In variable mark density, the ratio of 1s to total bits in patterns can be set to 1/8, 1/4, 1/2, 3/4, or 7/8. User-programmable patterns can range in length from 1 bit to 8M bits.
The 70843A is an integral component of the 71612A system.
