Agilent/Keysight 37719A

The Agilent/Keysight 37719A OmniBER 719A is a portable communications performance analyzer engineered for SONET, ATM, POS, and T-carrier network testing. It delivers comprehensive BER and jitter measurement, generation, and analysis across multi-rate optical and electrical interfaces. Designed for installation, maintenance, and manufacturing environments, this single-unit platform provides extensive test coverage for network elements, transmission systems, and ring turn-up operations.
