WaveGen™ - True 3x3 MIMO Signal Generator with Integrated Channel Emulator
WaveGen is the industry’s only integrated and complete solution to 3x3 MIMO receiver testing. Utilizing a single WBW2300 WaveBlade, it allows the tester to create every conceivable combination of 802.11 a/b/g/n frames and present them to the device under test from a point-and-click GUI. Simultaneously, the IEEE channel models can be set on a per-packet basis. Unlike solutions composed of single-output generators, WaveGen does not require knowledge of DSP modulation SW packages, tedious construction and download of I/Q, or stringing together multiple devices with specialized synchronization hardware.
Purpose built by MIMO radio engineers for MIMO radio engineers, the WaveGen addresses the needs of designers and testers of 802.11 radio and baseband functions. Perfect for design, production validation test (PVT), large-scale interoperability test (IOT) or system integration, this small, modular, single-card approach offers an easy-to-use push-button 3x3 MIMO signal generation solution.

Benefits
- Industry’s only integrated true line-rate, 3x3 MIMO 802.11n signal generator. No ganging of single-stream signal generators and complex software interfaces
- Purpose-built for 802.11n: minimal effort required to create waveforms and combination of any packets
- Infinitely variable packet generation; no need to worry about the amount of available memory
- Compact size: a complete 3x3 MIMO solution within one WBW2300 WaveBlade
- No need to download waveform files and install them on the test system
- Unbeatable scaling: combine up to 9 WaveBlades within a single WT90 chassis to create nine independent MIMO signal generators; daisy-chain WT90 chassis to increase scale further
- No need to invest in new hardware when moving to function and performance test: the WBW2300 also supports layer 2 through 7 traffic generation and analysis
- Multi user control allows one WBW2300 to be used for signal generation while another within the same chassis is used for function and performance test
