Agilent Technologies (HP) HP 37714A

PDH/SDH ATM Transmission Test Set The Agilent 37714A Transmission Tester is a compact solution to field maintenance test. This rugged modular tester complements the HP 37717B/C, providing a compact budget solution to applications not requiring jitter testing. SDH Testing The SDH module operates at STM-1e, STM-1o and STM-4o with a range of optical interface at 1310 and 1550 nm. In-service or out-of-service tests on PDH, SDH, transmission lines, or PDH payloads carried in SDH transmission systems, are supported. The operation of SDH network alarms error monitors, automatic protection switches, pointer processors and de-synchroniser circuits can be verified with this module. Drop / insertion of PDH payloads to / from the SDH signal and an error output are also available. SDH Alarm Scan and SDH Channel Scan features make this product the industry standard for ease of use.
