Specification

Relevant information

Introduction：

It supports sub-instrument functions, has 4 sets of VSA/VSG units, and can be allocated to 4 users at most for independent use at the same time. WT-428 is a kind of wireless network test instrument for testing the new generation 802.11be (Wi-Fi 7) protocol. The test frequency can cover the 400MHz-7.3GHz frequency band, and the test bandwidth can reach 400MHz. It supports 4096-QAM modulation, which can provide accurate, reliable and efficient R&D and mass production test solutions for Wi-Fi 7 products. It can meet the DEVM verification test requirements of Wi-Fi PA/FM products. It has two sets of independent signal transceiver units. A single machine can hold 2X2 MIMO test, and multiple machines can hold 8X8 MIMO test. The industry-leading test accuracy and stability can meet the requirements of R&D limit test.
