Fast frequency source for the PXI platform
July 2003
PLCs, DCSs & Controllers
Test and design engineers can generate high-frequency sine and clock outputs with the latest addition to the National Instruments line of PXI modular instrumentation. The NI PXI-5404 100 MHz frequency source, the fastest National Instruments source for PXI, can simultaneously generate sine and clock outputs up to 100 MHz with 1,07 µHz resolution and ±0,2 dB sine level accuracy.
Engineers can use National Instruments new frequency source for flexible clocking options in automated test equipment (ATE) systems, as well as for cost-effective sine wave generation for basic analog stimulus. Its flexible clock output levels address both TTL and CMOS technologies.
The simultaneous sine and clock outputs and sine level accuracy of ±0,2 dB of this new frequency source make it ideal for coherent sampling in ATE, functional test and design validation applications. It features 9 KHz to 100 MHz sine generation and DC to 100 MHz clock generation with sine amplitude adjustable from 1 to 2 Vpp, 12-bit vertical resolution and sinewave passband flatness of ±0,2 dB. With its phase-lock loop, the device can synchronize to the PXI backplane and other devices, such as high-speed digitisers.
The NI PXI-5404 frequency source comes with the IVI-compliant instrument driver NI-FGEN, which delivers full programming support for LabVIEW, LabWindows/CVI, Visual Basic and Visual C++. With the simulation mode now available in the NI-FGEN software, test and design engineers have the freedom to develop and prototype applications without the NI PXI-5404 hardware in their system.
