XM-23L4 is 4-Port 10/100/1000 Mbps UTP Ethernet Test Module. High test quality & reliable test result - The test modules are specifically built for production test at wire speed to ensure the quality and reliability of the test.

• XM-23L4:
  • 4-Port 10/100/1000 Mbps UTP Ethernet Test Module
• Flexible traffic generation and analysis
  • Real-time, wire speed generation and analysis of layer 2 and 3 traffic
  • Single / Burst / Multi-burst / Continuous packet generation
  • Frame size from 48 to 9212 bytes
  • Varies multiple address fields to create millions of unique flow
  • Random IFG generation support
  • Support 802.3x flow control
  • Independent operation in each module
• Extensive statistics
  • Real-time 64 bits counters that provide detailed statistics about every aspect of the packets being transmitted / received
  • External file logging for statistics and alerts
• X-Trailer for frame data integrity verification
• Generation and response to ARP and Ping for layer 3 testing

• High test quality & reliable test result - The test modules are specifically built for production test at wire speed to ensure the quality and reliability of the test
• High test throughput - The modules can generate more packets than conventional PC based solutions in shorter period and multiple DUTs can be tested simultaneously without causing degradation in test quality and test speed
• High density & low cost - A single NuStreams-2000 chassis can accommodate up to 64 Fast Ethernet ports or 48 Gigabit Ethernet ports thus reducing the per port cost of the tester
• Customizable test program - The modules are supported by API for the development of customized test programs. Generic production test program with pre-defined templates is available to minimize the development effor
