Digitiser switches to PCIbus

New from National Instruments is the NI PCI-5124, a PCI version of its popular 12bit, 200Msample/s PXI-based digitiser.

The NI PCI-5124 is a PCI version of the popular 12bit, 200Msample/s PXI-based digitiser from National Instruments.

Both the NI PXI-5124 and NI PCI-5124 digitisers use the latest commercial technology to deliver more than 75dBc spurious-free dynamic range (SFDR) on two simultaneously sampled inputs with 150MHz bandwidth.

Both devices are based on the NI SMC synchronisation and memory core architecture, which features up to 512Mbyte 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 NI 5124 digitisers ideal for a variety of measurement applications in consumer electronics, military, aerospace, semiconductor and medical device test.

These devices offer additional features such as software-selectable 50ohm and 1Mohm input impedance, 4Gsample/s random interleaved sampling (RIS) for repetitive signals and five trigger modes including video triggering.

Design and test engineers can use the National Instruments digitisers to rapidly 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 32, 256 and 512Mbyte memory options offers sophisticated 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.
