Agilent/Keysight J2300E

The Agilent/Keysight J2300E is a portable WAN protocol analyzer engineered for network performance monitoring, troubleshooting, and optimization across multiple protocol families and data rates. Operating from 50 bps to 155 Mbps, the J2300E delivers native support for Packet over SONET/SDH, Frame Relay, ISDN, X.25, HDLC, SDLC, SNA, Sync/Async PPP, and ATM-DXI, plus encapsulated LAN protocols over WAN links. ATM support extends to OC-3 (622 Mbps).

Built-in V-Series interfaces include RS-232C/V.24, RS-449/422/423, V.10/V.11, and V.35, with high-speed V-Series capability to 8.192 Mb/s available via plug-in module.
