The PX14400D Digitizer Board is a dual channel waveform capture board that provides a combination of high speed and high resolution sampling along with a very large memory capacity. This board is a companion to Signatec's PX14400A and is intended primarily for applications that require DC capability. The analog input bandwidth is set to 200 MHz via 3-pole Bessel filters on each input channel.

The PX14400D Digitizer Board has a primary sample-data RAM bank of 512 MB memory that may be used as an exceptionally large FIFO for acquiring non-stop, continuous data directly to either the PCI Express (PCIe) bus or the SAB. In Buffered Acquisition Mode (where the 512 MB RAM FIFO is used) the PX14400D is capable of sustaining 1400 MB/s over the PCIe bus. Significant test data has shown that recording with large FIFO buffering can be continuous at these rates even when operating in traditional non real-time environments such as the Windows operating system.

The PX14400D Digitizer Board employs up to two Virtex-5 FPGAs, where one of the FPGAs is available as an option for customers to implement their own custom in-line signal processing. A standard FIFO interface to the Signatec specific logic portion of the PX14400D along with control flags, an example program using the FIFOs/flags and a programmer's manual are provided with the optionally available PX14400D Firmware Development Kit. The PX14400D can be ordered either with or without this 2nd user accessible FPGA. Boards without the user FPGA are -DR (data recording only) models and boards with the user FPGA are -SP (signal processing) models.
