Agilent/Keysight E1675A

The Agilent/Keysight E1675A is a SONET/SDH transport overhead analysis module engineered for STS-48/STM-16 signal characterization at 2.4 Gb/s. This plug-in module integrates into Agilent 16700-series logic analysis mainframes and delivers dual electrical interfaces for both transmit and receive operations. The unit operates independently or within a complete test system for protocol-level overhead analysis and transport layer diagnostics.

Typical Applications

• SONET/SDH equipment validation and compliance testing


• Transport overhead protocol analysis at STS-48/STM-16 rates


• Integrated testing within 16700-series logic analysis platforms

Compatibility & Integration The E1675A requires mainframe integration with Agilent 16700-series logic analysis systems (OS A.02.00.00 minimum). Optional software control interfaces require Windows 7 SP1 through Windows 11 (64-bit preferred), Intel Core i5–class processor, 8 GB RAM minimum, and Keysight IO Libraries Suite 2024.1 or later. The optical interface may not be factory-installed on used units.
