Agilent/Keysight E1676b

The Agilent/Keysight E1676B is a Multi-Rate SDH/SONET Analyzer Module that tests and evaluates equipment in synchronous telecommunication networks. This C-size, triple-slot VXI module integrates into the HP 75000 Series 90 Modular SONET/SDH Analyzer and Broadband Series Test System (BSTS) to deliver comprehensive analysis across four standard transmission rates.

– Technical Specifications

The E1676B operates at SONET/SDH rates of 52 Mb/s, 155 Mb/s, 622 Mb/s, and 2.488 Gb/s, supporting STS-1/STM-0, STS-3/STM-4, STS-12/STM-1, and STS-48/STM-16 frame formats. The module handles concatenated payloads across all supported rates.

Payload add/drop capability functions at 52 Mb/s and 155 Mb/s in MULTIrate mode. Tributary add/drop capability extends to 52 Mb/s, 155 Mb/s, and 622 Mb/s in TRIButary mode, enabling interconnection with other Series 90 modules for comprehensive payload testing within STS-48/STM-16 and STS-48c/STM-16c signals.

– Key Features

• Frameword error stressing and alarm generation (AIS, FERF)
• B1, B2, B3, and Data error insertion
• Detection of AIS, FERF, Out of Frame (OOF), Loss of Signal (LOS), and Loss of Pointer (LOP)
• Full programmable overhead byte management with sequencing capability
• Pointer adjustment and stress testing
• PRBS bulk fill generation and measurement for concatenated payloads
• Frame and byte capture functionality
• Trigger outputs for events and alarm conditions

– Typical Applications

The E1676B addresses validation of SDH/SONET transmission equipment, network element testing, payload integrity verification, and fault condition simulation across multi-rate synchronous networks.

– Compatibility & Integration

This module functions as a component within the HP 75000 Series 90 Modular SONET/SDH Analyzer platform and the Broadband Series Test System (BSTS), providing modular test integration for complex network analysis configurations.
