SHF 11100 AError Analyzer

SHF 11100 A – Rev. 1.4 – 24/JUN/2008

Page 1/5

Description
The SHF 11100 A is an error analyzer plug-in which can be fitted into any the SHF 10000 Series
mainframes.
1

It has broadband operation from 1.5 to 56Gbps and features high sensitivity and a wide clock
791115phase margin. It allows the analysis of PRBS signals with pattern lengths of 2 -1, 2 -1, 2 -1, 2 -1,202331
2 -1, 2 -1 and 2 -1. User patterns can also be analyzed.
In a back-to back configuration with the SHF 12100 B, the system Q-factor is an impressive 25(28dB), measured using a 2^31-1 PRBS pattern.
