National Instruments 785650-01 DC-Coupled FlexRIO Digitizer Device

The National Instruments 785650-01 is identified as a PCle-5774, which is a DC-Coupled FlexRIO Digitizer Device. It is designed for time-domain measurements across various fields, including medical imaging, particle physics, and scientific instrumentation. This FlexRIO digitizer offers 3.2 GHz of analog bandwidth with a 16-bit resolution, which provides precise and detailed signal capture. This 785650-01 model is equipped with two voltage input channels, and it can achieve a maximum sample rate of 6.4 GS/s.

The 785650-01's KU060 FPGA offers enhanced performance with 331,680 LUTs, 2,760 DSP48 slices, and 38.0 Mb of embedded Block RAM. The KU060 also includes multi-gigabit transceivers (MGT) for high-speed data transfers, which is not available in the KU035 model. This FPGA supports data transfers via DMA, interrupts, and programmed I/O, additionally offering MGT for advanced data handling.

The onboard DRAM of the 785650-01 device provides 4 GB of memory (2 banks of 2 GB each) with a clock rate of 1064 MHz and a physical bus width of 32 bits. This configuration supports a maximum theoretical data rate of 17 GB/s. The model can be configured by LabVIEW-programmable Xilinx Kintex UltraScale FPGA.
The analog input section of the 785650-01 digitizer features two single-ended simultaneously sampled channels. These channels use SMA connectors and have an input impedance of 50 Ω. The device supports both internal and external sample clocks with each operating at 3.2 GHz. In dual-channel mode, the sample rate is 3.2 GS/s per channel, while single-channel mode achieves a rate of 6.4 GS/s. The ADC utilized is the ADC12DJ3200, which provides a 12-bit resolution for accurate signal digitization.

In terms of bus interface, the device features a PCI Express Gen-3 x8 card edge form factor. It is compatible with x8 and x16 PCI Express slots, which ensure broad compatibility and ease of integration into existing systems. Power requirements vary based on the LabVIEW FPGA VI used, with a maximum total power consumption of 75 W.

It is instructed to operate this 785650-01 DC-Coupled FlexRIO Digitizer under the temperature range of 0 to 45 degrees Celsius. It can be mounted at the maximum altitude of 2000 MSL and weighs only 990 g (35 oz.).
