The Agilent/Keysight 37701B is a portable T1 datacom tester for installation and maintenance of T1, fractional T1, and datacom circuits. It delivers comprehensive measurement solutions in a single unit, supporting out-of-service terminal testing and in-service monitoring including through mode and drop-insert testing. The instrument performs bit error rate testing (BERT) on unchannelized and channelized circuits, signaling bit control with capture and dialing, and G.821 measurements with timestamped graphical logging.
