PXI digital waveform generator/analysers for flexible digital interfacing

25 August 2004 Test & Measurement

National Instruments is offering two new PXI digital waveform generator/analysers for common logic families. The PXI modules are ideal for interfacing to high-pin-count digital ICs and electronics in a variety of industries including semiconductor, military/aerospace and manufacturing test. The company plans to also release PCI versions soon.

The NI PXI-6542 and PXI-6541 digital waveform generator/analysers offer 100 MHz and 50 MHz maximum clock rates and 32 channels with per-channel direction control. Engineers can software-configure the modules to interface with a broad set of common logic families of 5,0 V, 3,3 V, 2,5 V and 1,8 V.

The modules add high-density digital capabilities to NI's 100 MS/s mixed-signal suite of instrumentation devices. They are built on the company's synchronisation and memory core (SMC) architecture, a fundamental technology of the mixed-signal suite. The SMC architecture delivers a timing and synchronisation engine, data transfer cores and deep, flexible memory. The synchronisation engine can lock multiple instrument modules together through a set of shared clocks and trigger signals.

Using the SMC-based modules, engineers can synchronise multiple digital modules for high-channel-count applications or synchronise digital with analog modules for mixed-signal applications.

Test applications can be created by using two powerful software tools: Express VIs in the National Instruments LabVIEW 7.1 graphical development environment and the NI Digital Waveform Editor for interactively creating and editing digital patterns.
