National Instruments (NI) announced two 200MSps modular instruments that extend the company's mixed-signal measurement capabilities.

The new modules, based on the company's Synchronization and Memory Core (SMC), double the available sample rate and memory depth of the company's digitizer and arbitrary waveform generator product families. When combined with NI's precision DC, RF and high-speed digital PXI instruments, the new modules are suitable for a variety of applications in consumer electronics, semiconductor, military/avionics and scientific research.

The PXI-5124 12-bit, dual-channel digitizer and the PXI-5422 16-bit arbitrary waveform generator use the latest commercial semiconductors to extend the SMC architecture by increasing sample rates to 200MSps and memory depth to 512MB per channel. The PXI-5124 digitizer offers 75dBc spurious-free dynamic range (SFDR) and 150MHz bandwidth, while the PXI-5422 arbitrary waveform generator delivers <6 percent pulse aberration and a 1.8ns rise time.

Since all of the company's mixed-signal modular instruments are built on the common SMC architecture, they can tightly synchronize with other SMC-based instruments, such as the NI PXI-6552 100MHz digital waveform generator/analyzer. With module-to-module jitter of <20ps rms, the synchronization of the SMC makes high-performance mixed-signal or high-channel-count measurement systems possible. In addition, both modules can import external sample clocks, reference clocks and triggers through front panel connectors or the PXI trigger bus.

NI said that design and test engineers can use the 200MSps digitizer and arbitrary waveform generator to quickly build stimulus/response systems anywhere in a product's development flow using the new NI SignalExpress interactive measurement software as well as LabVIEW 7.1 and NI TestStand test management software. With the Express technology available in each of the software packages, engineers can interactively configure the digitizer and arbitrary waveform generator with little programming.
