Datasheet
SHF 12100 A
50 Gbps Bit Pattern Generator

Description
The SHF 12100 A is a bit pattern generator plug-in which can be fitted into the SHF 10000 A
mainframe.
Operation is from 6Gbps up to 50Gbps. It allows the production of PRBS signals with patternlengths of 27-1, 29-1, 211-1, 215-1, 220-1, 223-1 and 231-1. User-programmed patterns can also beloaded into the instrument.
The operating bit rate is determined by the clock frequency – the instrument can operate at both fullclock and half clock, so either a 25 GHz or a 50 GHz signal is required for 50 Gbps operation. Sub
rate outputs can be optionally fitted to provide four channels with data rates from 1.5…12.5Gbps.

Features
Broadband operation up to 50 Gbps
Operation by intuitive software interface
High quality adjustable output signals
Available PRBS pattern lengths: 27-1, 29-1, 211-1, 215-1, 220-1, 223-1, 231-1
Up to 128 MBit user pattern
Two independent, programmable frame trigger outputs
Sub rate clock outputs

Options
010 – Four differential 1.5 to 12.5 Gbps sub-rate outputs
020 – Two differential 3 to 25 Gbps sub-rate outputs
DFF – D-type retiming flip-flop on output
Note:
Option 010 and 020 cannot be supplied at the same time
With option DFF the output amplitude is fixed and the instrument works only in full clock mode
