With this combination of high resolution and deep memory, you can generate long, precise aperiodic waveforms, ideal for a range of applications in communications, consumer electronics, scientific research, automotive, and military/aerospace. Because the NI 5421 uses the PCI bus, waveforms can be downloaded up to 280 times faster than with GPIB-based AWGs. With the NI Synchronization and Memory Core (SMC) architecture of the NI 5421, you can create stimulus/response systems with digitizers and digital waveform generator/analyzers or synchronize multiple arbitrary waveform generators to form a phase-coherent multichannel system. Analog Output Performance Because of its 100 MS/s, 16-bit digital-to-analog converter (DAC) and clean back-end analog design, the NI 5421 has a close-in spuriousfree dynamic range (SFDR) of 91 dBc and an average noise density of -148 dBm/Hz. These features make it ideal for even the most stringent frequency-domain applications common in communications. Depending on your signal and application needs, you can select from 2x, 4x, or 8x interpolation for an effective sampling rate up to 400 MS/s. For demanding time-domain applications, the NI 5421 has
