Handheld network tester provides protocol analysis, packet capture, cable testing

The tester from Psiber Data Systems also conducts PoE testing and determines the actual power used by a powered device.

December 4, 2009Psiber Data Systems recently launched the LanExpert, which the company describes as a handheld network analyzer featuring protocol analysis, packet capture, traffic generation, cable testing, and IPv4/IPv6 support.

The LanExpert uses a color touch screen interface to access a suite of test and analysis functions. The tester’s inline mode allows users to non-intrusively monitor 10/100/1000Base-T network traffic to identify protocols, port usage, VoIP statistics, and network utilization.

Psiber says the LanExpert can capture and store up to 10,000 packets with user-defined filters for detailed analysis in the field or downloaded over the network or to a USB flash drive. Using either RJ-45 port, tests including ping, link, trace route, DHCP, and discovery are used to identify network problems. The tester can generate up to 100 percent traffic loading with control of packet rate and size to demonstrate network performance at various traffic levels. Also, a stress test that generates traffic and measures performance metrics, in accordance with RFC 2544, is also provided. Stress tests can be conducted using two independent ports on a single unit, or used with a second unit located remotely on a network. Power over Ethernet tests include voltage and inline current measurement to determine the actual power used by a powered device. The LanExpert also tests cables for shorts, opens, split pairs, reversed pairs, and cable length. It can generate tone for cable tracing.

The tester lists for US$1,895.
