Tutorial

Basic BERT testing with the GB1400

A critical element in digital transmission systems is how error-free its transmissions are. This measurement is made by a bit-error-rate tester (BERT). The GB1400 Generator (Tx) and Analyzer (Rx) are designed to operate at bit rates up to 1400 Mb/s. These portable instruments provide PRBS or User Defined Patterns (up to 1Mbit deep) for high speed BERT testing.

Objective of Tutorial

Understand GB1400 instrument setup for BER testing using PRBS patterns.

Procedure

This tutorial programs the GB1400 Generator to provide PRBS clock and data signals for the Analyzer. Using AUTO-SEARCH features, the Analyzer will synchronize to the incoming PRBS test pattern. Bit Error Rate (BER) measurements will be performed on both good (error-free) and bad (user injected faults) data streams.

Key Feature of Tutorial

This lab demonstrates the use of AUTO-SEARCH Synchronization.
