MIMO Test

"NI hardware and software platforms provided the capability and flexibility to support this critical development by helping us efficiently develop a highly reliable test system that met all of the client requirements and a tight product release schedule. "

Automated Testing of Advanced, High-Performance, Point-to-Multipoint Radio Systems Using National Instruments Software and PXI Hardware

Using PXI hardware and NI LabVIEW software, you can develop effective phase-coherent RF measurement systems. PXI makes it possible to synchronize up to four RF vector signal generators or up to four RF vector signal analyzers. This architecture works with a shared local oscillator (LO) between each signal generator and a separate shared LO between each signal analyzer. With this system, you can perform accurate phase-coherent RF measurements for multiple input, multiple output (MIMO) and beamforming applications at a low cost. NI platform benefits include the following:

- Tight synchronization with less than <0.1 deg of channel-to-channel jitter

- Up to four channels of phase-coherent RF signal generation in a single PXI chassis

- Up to four channels of phase-coherent RF signal acquisition in a single PXI chassis

- Ideal prototyping platform for up to 4x4 MIMO systems

- Ready-to-use LabVIEW example code


Using the NI LabVIEW graphical programming environment, combined with the built-in timing and synchronization capabilities of PXI hardware from NI, you can configure multichannel phase-coherent measurement systems for MIMO and beamforming applications.
