PRODUCTION LINE TESTING

Test. Improve. Repeat.

Production line testing involves checking the quality of products as they leave the assembly line to identify any problems before they reach the customer. This improves customer satisfaction and helps minimize service & repair costs.

Conducted in industrial environments quite different from R&D labs, production line testing is frequently performed by unskilled assembly line workers. As a result, production line test equipment needs to be both robust and very easy to use.

For Ethernet products, there are a number of relevant types of testing that require an Ethernet traffic generation and analysis solution.

  • Router test:
    Bi-directional traffic generation between WAN and LAN ports, could be multiple LAN ports to single WAN port, or one WAN port to multiple LAN ports. Test of throughput and failures. The test may be configured with values for packet size, bandwidth, packet loss and other stream parameters. The result of the test is a pass/fail message. In the case of fail details about the failure for later analysis.
  • Two-way interaction test:
    Generate traffic between all ports, or between odd and even ports, or one direction traffic generation, with or without VLAN tagged frames. The result of the test is a pass/fail message and in the case of fail details about the failure for later analysis.
  • Aggregation test:
    Supports one-to-many and many-to-one traffic generation
  • Loopback test:
    a configurable number of ports on e.g. a DUT such as a switch or a router. The test may be configured with values for packet size, bandwidth, packet loss and other stream parameters. The result of the test is a pass/fail message and in the case of fail details about the failure for later analysis.
  • PON aggregation test:
    Traffic is transmitted one-to-many and packets are sent both up and downlink. The test may be configured with values for packet size, bandwidth, packet loss and other stream parameters. The result of the test is a pass/fail message and in the case of fail details about the failure for later analysis.

Vantage is Xena’s solution for testing devices that use Ethernet traffic before they leave the factory. Based on the Valkyrie HW, Vantage can test all Ethernet speeds up to 400GE and is available both in a high-port density 4U chassis or a compact 1U chassis. VantageManager is a powerful yet very easy-to-operate browser-based UI, designed specifically for this type of testing. It has proven to be the fastest platform for production line testing and rock-solid features like 3-click test cycles, multiple scripting options, and easy MES integration make it an industry leader.

CASE STORY

QA TESTING PON DEVICES

A major equipment manufacturer in China’s digital information and TV industry needed a production line test solution for Quality Assurance (QA) of 1GE PON devices. The solution needed to support long tests – up to 72 hours – as well as production tests taking just 10 seconds. Having experienced reliability issues with their previous solution, the manufacturer needed a production line tester that generated consistently accurate results.
