Description
The SHF 12100 B is a bit pattern generator plug-in which can be fitted into the SHF 10000 Series
mainframes.
1Operation is from 1.5 Gbps up to 56 Gbps . It allows the production of PRBS signals with pattern lengths
791115202331of 2 -1, 2 -1, 2 -1, 2 -1, 2 -1, 2 -1 and 2 -1. User-programmed patterns can also be loaded into theinstrument.
The operating bit rate is determined by the clock frequency – the instrument can operate at both full clock
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 either four channels with data rates from 1.5 …12.5 Gbps or twochannels with data rates from 3 …25 Gbps.
