The PXDAC4800 is an exceptionally high-speed four channel Digital to Analog Conversion (DAC) board which may be used as an Arbitrary Waveform Generator (AWG), a waveform playback device, or for generating multiple communication frequency bands.
Each DAC can output data at a maximum real rate of 1.2 GSPS at 14-bit for two channels or at 8-bit for four channels, or 600 MSPS at 14-bit for four channels. Each output signal has a bandwidth of up to 400 MHz for AC-Coupled configuration or up to 590 MHz for DC-Coupled configuration. Output waveforms may be “per-trigger” or “continuously looped” from the on-board 1 Gigabyte memory.
The DACs can also be provided with a continuous data stream via the PCI Express (PCIe) bus up to 900 Megabytes per second (MB/s). This PCIe bus rate allows for providing up to 112.5 MSPS addressable bandwidth at full 14-bit resolution for each of the four analog outputs.
