The WT-328E is a high-end wireless network test instrument for high-end Wi-Fi 6E WLAN product testing. It supports the radio frequency signal test of 400M-7.3G frequency band, and can provide reliable and efficient RF test scheme for Wi-Fi 6E products.With two independent test units, the single box supports 2x2 True MIMO test and MU-MIMO; with excellent test specifications and efficient test efficiency, it can meet both R & D and production test scenarios.

■ WLAN(802.11 ac/ax 80/80+80/160)

■ WLAN(802.11 a/b/g/n/p)

■ 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

■ Wi-Fi 6E Measurement

The test frequency band is extended to 400M~7.3G, supporting the latest Wi-Fi 6E standard in the industry, and the typical residual EVM of 160M bandwidth reaches -47dB. To meet the DUT's optimal performance test, the test accuracy is higher, which is beneficial to improve the throughput.

■ MIMO Measurement

Have two sets of test units

Single machine supports 2x2 True MIMO test

Stacking machines support 8x8 True MIMO test

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