WT-328 wireless connection tester

           WT-328 is a dedicated instrument for the production and testing of high-end WLAN products. It supports radio frequency signal testing in the 400M-6G frequency band. It can provide a reliable and efficient radio frequency test solution for the next-generation WLAN protocol Wi-Fi 6 (802.11ax). Two sets of independent test units, support MU-MIMO, a single machine can support 2X2 True MIMO testing; perfectly inherit the 8 ports of the WT-20X series Parallel testing technology and efficient operation characteristics take into account the testing requirements of the R&D end and the production line.

■ WLAN(802.11 a/b/g/n/p/ac/ax)

■ Bluetooth(1.0/2.0/3.0/4.0/4.1/4.2/5.0)/BLE 

■ MIMO/MU-MIMO

■ IoT:ZigBee/Z-Wave…  

■ Navigation:GPS/BDS

■  WAVE 2 Test

Provides 240M sample rate option (analysis bandwidth 180M).Based on the test capabilities of the original WT-20X series, the 802.11ac 160M/80M+80M service is supported.

■ 11ax Test

Supports 802.11ax standard, with typical residual EVM of 80M bandwidth reaching -46dB.The testing satisfies the optimal performance of the DUT,with higher test accuracy and is conducive to improving the straight-through rate                                                              

■ MIMO Test

WT-328 has two independent test units. A single machine supports 2x2 True MIMO and MU-MIMO test . Stacking multiplemachines supports: 8x8 True MIMO.

■ 8-port parallel Test

With advanced high-speed, high isolation switch matrix and the port isolation is up to 110dB (typical). It supports 8-port parallel tests to maximize instrument utilization and reduce product testing costs.

■ High Reliability

WT-328 can protect DC voltage below 5V. Under the condition of contact discharge, anti-static capacity can reach 7KV.
