The National Instruments PXI-5421 is a high-performance PXI Waveform Generator designed for diverse test and measurement applications, particularly in communication, research, automotive, and military/aviation sectors. This compact 3U PXI module occupies a single slot and features a maximum sample rate of 100 MS/s, complemented by 16-bit DAC resolution and onboard memory options including 8 MB, 32 MB, 256 MB, and 512 MB, allowing for the generation of precise arbitrary and periodic waveforms. The PXI-5421 delivers a maximum bandwidth of 43 MHz, significantly enhancing waveform download speeds—up to 280 times faster than traditional GPIB-based generators.

Integration capabilities are bolstered through Synchronization and Memory Core (SMC) technology, enabling users to employ digitizers for advanced jolt/reaction frameworks and synchronize the generator with other waveform generators for phase-coherent multichannel generation. The device operates using NI-FGEN driver software, encompassing extensive compatibility with application development environments such as LabVIEW, LabWindows/CVI, and Measurement Studio.

Physical specifications include dimensions of 21.6 × 2.0 × 13.0 cm (8.5 × 0.8 × 5.1 in) and a weight of 345 g (12.1 oz). The front panel is equipped with two LED indicators for monitoring the PCI bus and onboard generation hardware status. The PXI-5421 also features a software-selectable output enable function for channel 0 and can safely connect to a 50 Ω (±12 V) source without risk of damage. A warranty period of 2-3 years is provided, and user manuals are available for download. For pricing information, please contact a sales representative.
