The U5309A is a multichannel PCIe 8-bit digitizer with programmable on-board processing. This ADC card occupies a single full-length PCIe slot of the host computer and captures signal on 1, 2, 4 or 8 channels at 2 GS/s, 1 GS/s or 500 MS/s. Featuring an analog bandwidth from DC to 500 MHz and a large DDR3 memory for long acquisition time, the U5309A also includes a Xilinx FPGA allowing implementation of custom real-time processing algorithms.

While providing high performance in a small footprint, it offers an ideal data acquisition platform for many commercial, industrial and aerospace & defense embedded systems and is particularly suited for OEM Applications.

The U5309A digitizer includes a digitizer firmware (-DGT) with up to 2 GS/s per channel.

Moreover, additional firmware options are available:

The real-time sampling and averaging option (-AVG) that enables synchronous real-time sampling and accumulation up to 2 GS/s on a single-channel and 1 GS/s on dual-channel

The real-time signal peak detection option (-PKD) that provides synchronous real-time sampling and peak detection up to 2 GS/s on single-channel and 1 GS/s on dual-channel

The triggered simultaneous acquisition and readout (-TSR) that is dedicated to applications requiring no trigger loss, achieving longer recording time when compared with standard digitizer

Besides, -AVG and -TSR firmware can be combined allowing signal acquisition, real time averaging and data readout simultaneously, on a single channel.
