原廠英文說明
The NI 5421 Series are 100 MS/s arbitrary waveform generators (AWG) featuring 16-bit resolution and up to 256 MB of onboard memory in a compact, 1 slot 3U PXI module or PCI board. With this combination of high resolution and deep memory, the user 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 Series use 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 Series, the user 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.
