IQnxnplus WiMAX MIMO R&D Test Solution

The LitePoint IQnxnplus is a modular Multi-Stream MIMO test system that provides you with multiple, simultaneous TX and RX data streams for testing WiFi and WiMAX devices with up to 4 TX and 4 RX channels. These test systems offer program compatibility with IQmax test systems allowing test programs to be developed on an IQnxnplus system, and then deployed on individual IQmax systems for high-volume testing.

 

You can configure the IQnxnplus system from 2 TX and 2 RX channels to 4 TX and 4RX channels to meet your MIMO testing needs. The modular approach allows you to start with a Multi-Stream MIMO-ready unit (1 TX and 1 RX channel), and then add a synchronization unit and multiple IQmax-750 Vector Signal Analyzer (VSA) and Vector Signal Generator (VSG) combination units. The resulting system provides complete Multi-Stream MIMO test capabilities for both WiFi and WiMAX devices.

 

WiMAX Wave2 and 802.11n device standards serve different end-customer segments, but both use Multi-Stream MIMO techniques to offer you more robust data links with higher bandwidth. To properly validate these designs in R&D, you need a true Multi-Stream MIMO solution. Real world devices lack perfect isolation between channels, causing measurement errors when trying to validate these devices using switched MIMO approaches. This is particularly evident when comparing EVM measurements using switched EVM and Multi-Stream EVM testing.

 

WiMAX Wave2 systems can be verified with the IQnxnplus because its distributed LO and trigger system maintains locked phase between channels throughout the entire frame which is typically 5 ms
