Virtual Instrumentation Case Study

Application

Boeing used LabVIEW and 7 PXI chassis to

collect over 300 channels of acoustic data

simultaneously in their research todecrease noise during takeoff

NI Products

LabVIEW, PXI

"Using NI software and hardware, we were able to

create a high-end, low-cost system that could distribute the acquisition system across multiple chassis, tightly

synchronize all channels, provide high channel count with full bandwidth on all channels simultaneously, and

allow virtually unlimited channel-count expansion.

-- James Underbrink, Boeing Aero/Noise/Propulsion Laboratory

LabVIEW and Multicore

There was no need to rewrite our applicationfor the new multicore

processing platforms .

- Scott Sirrine, Eaton Truck Division

Application:Eaton Corp. created a portable in-vehicle test

system for truck transmissions. Using the same

LabVIEW code on multicore processors

increased their overall throughput without having

to change application code.
