  • Name: WT-208 Wireless network multiplex test instrument
  • No: 0004
A highly efficient production test solution that supports four channels parallel testing!
 
■   Supports four channels parallel testing and the test efficiency multiplies。
 
■   The AP's dedicated network port makes it easier to set up a test environment.
 
■   Over 90 dB isolation can ensure parallel test reliable and high-efficient.

       The WT-208 tester is a high efficient production test solution, which includes all the functions and features of the WT-200, and adding high-performance Switch-Matrix and Network Processing Engine,becomes a high-efficiency multi-OUT test system.
 
Extensible Business:
    ■ Support 802 .11 a/b/g/n/ac test;
    ■ Support Bluetooth and ZigBee test;
    ■ Test efficiency is two times of dual-port instrument;
    ■ Up to 4 APs can be connected to the instrument directly;
    ■ High isolation(port to port);
    ■ Support over 300 ATE software;
    ■ Support R&D interface;
    ■ Support up to 4 different products test simultaneously;
    ■ Host and screen can be matched flexibly in quantity, from 1 to 4 supported.
