Setting Up ParBERT 43G
This chapter describes how to set up ParBERT 43G systems.
The Agilent 81250 ParBERT 43G is a solution for generating and
analyzing electrical data streams of 38 Gbit/s up to 43.2 Gbit/s.
It allows you to stimulate and analyze 16:1 multiplexers and 1:16
demultiplexers at data rates of 2.7 Gbit/s and 43.2 Gbit/s, according to the
OC-768 and SFI-5 (Serdes Framer Interface 5) data range.
It allows you also to determine the bit error rate of transmission lines or
serial devices operated at 43.2 Gbit/s. It supports the investigation of
FEC devices at 43.01841 Gbit/s to include the FEC rate resulting from
255/236 overhead.
For data generation, sixteen 2.7 Gbit/s data generators are multiplexed to
create a 43.2 Gbit/s data stream.
On the analyzing side, a 43.2 Gbit/s data stream is demultiplexed and fed
into sixteen 2.7 Gbit/s data analyzers.
The data streams to be generated or expected, as well as the signal
frequencies and levels, are controlled by the ParBERT user software.
This chapter explains:
• What constitutes a ParBERT 43G system (see ”ParBERT 43G
Components” on page 58).
• How to set up a ParBERT 43G system (see ”Setup Procedure” on
page 60).
• How to connect all the frontends to the MUX or DEMUX module (see
”Connections of the MUX/DEMUX Modules” on page 61).
• How to set up ParBERT 43G systems that exceed the capabilities of a
bundle (see ”Special Configurations” on page 63).
• How to connect the internal or an external clock to ParBERT 43G
systems (see ”Clock Connections” on page 64).
