The HP 70842B eerror detector module complements the pattern generator module. The HP 70842B occupies 4/8 MMS module slot and has five Input/Output ports, two on the front panel and three on the rear panel.
The Error Detector counts bit errors by comparing the incoming data bit-by-bit with the internally generated reference pattern. All measurements run during the gating periods, with the exception of Delta Error Count and Delta Error Ratio which run continuously.
HP 70842B option H50 Error detector Module 0.05 to 3 Gbit/s, 4-slot size, two I/O ports on front and one on rear. Module could be part of the HP 71603B Error Performance Analyzer or part of Pattern Generator 71604B.
