The Agilent 37704A is a comprehensive, field-portable, SONET, DS3, and DS1 test set for applications up to 622 Mb/s. It provides generation and analysis of VT (DS1) and DS3-mapped SONET signals, with full control of section, line, and path overhead bytes. Plug-in modules provide connection to a range of optical and electrical interfaces. Errors, alarms, and T1X1 pointer movement sequences are generated to stress equipment up to and beyond ANSI standards.
