NATIONAL Instruments has released the NI PCI-5124, a PCI version of its 12-bit, 200MS/s PXI-based digitiser.

The NI PXI-5124 and NI PCI-5124 digitisers deliver more than 75dBc spurious-free dynamic range (SFDR) on two simultaneously sampled inputs with 150MHz bandwidth. Both devices are based on the NI Synchronisation and Memory Core (SMC) architecture, with up to 512MB of onboard memory per channel, fast data transfer and tight synchronisation. Design and test engineers can synchronise SMC-based modular instruments within tens of picoseconds for high-channel-count and mixed-signal applications.

High resolution at fast sampling rates makes the digitisers suitable for measurement applications in consumer electronics, military, aerospace, semiconductor and medical device test applications. These devices offer additional features such as software-selectable 50Ω and 1MΩ input impedance, 4GS/s random interleaved sampling (RIS) for repetitive signals and five trigger modes including video triggering.

Design and test engineers can use the digitisers to develop a measurement system with Express technology using NI LabVIEW, NI TestStand or SignalExpress throughout the product development flow from research and design to validation and manufacturing. In addition, the NI Spectral Measurements Toolkit included with the 32MB, 256MB and 512MB memory options offers frequency-domain measurements such as power spectrum, peak power and frequency, in-band power, adjacent-channel power and 3D spectrogram for NI LabVIEW and LabWindows/CVI.
