The Anritsu ME7760B 43.5 Gbit/s BERT Systemåis composed of five hardware elements plus software that runs on a GPIB-connected PC. Each system element is described on a separate product page: click on the links below to see these 43.5G BER products. ME7760B is the standard system, and ME7760A is a lower-cost version. The ME7780A 48G BER Test Solution is a similar system available for higher rate signals. The signal output side consists of a 50G or 65G signal generator (MG3690B Series) for generating the clock signal, a pulse pattern generator (MP1775A) for generating four channels of SDH/SONET patterns, and the MP1803A 4:1 multiplexer (MP1801A for the ME7760A system) for multiplexing these signals into a 43.5 Gbps signal. The receive side consists of the MP1804A 1:4 demultiplexer (MP1802A for the ME7760A system) for splitting the 43.5 Gbps signal into four channels and an error detector (MP1776A) for measuring the error rate of the four channels.
