Agilent/Keysight J2300D

The Keysight J2300D Advisor WAN Protocol Analyzer combines a 300 MHz Pentium processor with specialized acquisition hardware for comprehensive protocol analysis across WAN, ATM, and encapsulated LAN networks. The instrument monitors and decodes traffic at full line speed from 50 bps to 622 Mbps without data loss, integrating multiple serial interfaces and PCMCIA expansion slots for flexible connectivity. With 768 KB capture buffer and 128 MB RAM, the J2300D delivers real-time analysis of Frame Relay, ATM, ISDN, X.25, HDLC, SDLC, SNA, and asynchronous PPP protocols.

Its 10.4-inch active matrix color display (640 x 480 VGA) and Windows 98 environment provide operator control, while built-in BERT capabilities measure bit errors, block errors, errored seconds, and G.821 performance metrics simultaneously.
