HP / Agilent 37722A Telecom Analyzer

The HP/Agilent 37722A Telecom Analyzer is a portable bit error rate and signal measurement instrument for in-service and out-of-service testing on CEPT digital circuits and services. It performs framed and unframed pattern generation and measurement at 2 Mb/s, with support for n × 64 kb/s testing. The field-portable design enables rapid deployment for installation, maintenance, and troubleshooting across telecommunications networks.
