Product Specs: Error Detector Module for 71603B. 100
Mb/s to 3Gb/s
The HP 70842A error detector module complements the pattern
generator module. The HP 70842A occupies 418 MMS module slot and has five
Input/Output ports, two on the front panel and three on the rear panel.
Operating Frequency Range: HP 70842A: 100Mbit/s to 3Gbit/s. Patterns PRBS, zero
substitution/variable mark density test patterns, and word test patterns are as
specified for pattern generator modules. 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.
The error analysis measurements are based on CCITT Rec G.821 and derived from
the bit error results. Front Panel LEDs for Gating, Clock Loss, Data Loss, Sync
Loss, Errors, and HP-IB / MSIB.
