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).
