National Instruments Lowers Test Costs
New NI PXI-5105 Eight-Channel Digitizer Ideal for building
High-Channel-Count Systems in Application Areas such as Ultrasonic Testing

NEWS RELEASE July 18, 2006 National Instruments announces the new NI PXI-5105 eight-channel digitizer, the lowest price-per-channel high-speed data acquisition product in its class, which offers a cost-effective alternative to systems that use multiplexed A/D converters or switches to increase channel count. Engineers and scientists can use the PXI-5105 60 MS/s, 12-bit digitizer to increase the number of analog input channels in their systems while lowering test costs. The new module extends the National Instruments family of high-density, simultaneous-sampling data acquisition products to more than 20 devices ranging from 12 to 24 bits, up to 60 MS/s, up to 512 MB onboard memory and up to eight channels on a single 3U PXI or PCI device.

Engineers can configure the PXI-5105 digitizer through software to perform typical oscilloscope measurements as well as custom measurements in many applications. In particular, the PXI-5105 digitizer is ideal for building high-channel-count systems in application areas such as ultrasonic non-destructive test (especially linear- and phased-array applications that require phase coherence), medical imaging including ultrasound and magnetic resonance imaging (MRI), seismic imaging and general ATE applications. To expand channel count beyond eight channels, the PXI-5105 builds on the PXI platform to deliver picosecond-level synchronization accuracy among modules. With this capability, engineers can build phase-coherent systems of up to 136 channels in a single 4U height, 19-inch rack-mountable PXI chassis, which they can expand to more than 5,000 channels using multiple PXI chassis.

LabVIEW Ultrasonic Starter Kit

Engineers can integrate the PXI-5105 digitizer with a variety of NI hardware including digitizers, signal generators, high-speed digital I/O and multifunction data acquisition devices to create a custom measurement system. The module also works with all National Instruments software including NI LabVIEW as well as other common development environments such as C, C++ and Microsoft Visual Basic. Engineers working on ultrasonic non-destructive test applications can accelerate their application development with the LabVIEW Ultrasonic Starter Kit, which is available as a free download at ni.com/digitizers/highdensity.
