WT-328 wireless connection tester

A production test solution for the next generation WLAN protocol 802.11ax!
 
■   Provide 240M sampling rate option (analysis bandwidth 180M). Based on the perfect inheritance of the test capabilities of the original WT-20X series instruments, it has realized the support for 802.11ac160M/80M+80M services.
 

■ Support the industry's latest Wi-Fi 6 (802.11ax) standard, and the typical value of residual EVM for 160M bandwidth reaches -47dB. To meet the DUT's optimal performance test, the test accuracy is higher, which is beneficial to improve the through rate.

■ Have two sets of test units. Stand-alone supports 2x2 True MIMO testing; stacking supports 8X8 True MIMO testing; supports MU-MIMO.

■ It has an independent high-power output port (Port 9), supports +10 dBm output, and can provide a high-power verification maximum receiving level. Meet the needs of extreme performance testing in the product development stage.

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; newly added port 9 ports, support high power output, meet the needs of extreme performance testing during product development; 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.
