Description
The 781419-02 is part of the PXI Reconfigurable FPGA Digitizers category, specifically the NI-5771 model. This digitizer is an AC-coupled adapter module designed for NI FlexRIO systems. It features a 2-Channel, 900 MHz Bandwidth, 8-Bit configuration, making it a versatile tool for a wide range of high-speed data acquisition applications.
It offers a high sampling rate of 3.0 GS/s when operating in single-channel mode and 1.5 GS/s in dual-channel mode. This ensures precise readings across its operational bandwidth. The NI 5771 is equipped to handle an analog input voltage range from -0.675 V to 0.675 V, catering to a broad spectrum of signal strengths.
Compatibility with Virtex-5 and Kintex-7 FPGAs allows for flexible and powerful configuration options, enabling users to tailor the system to their specific needs. The module includes 2 SMA type connectors (labeled AI 0 and AI 1) for analog input, emphasizing its focus on high-quality signal acquisition with DC input coupling.
An onboard clock running at 1.5 GHz, of the VCXO type, provides an internal sample clock, ensuring precise timing for all measurements. Additional connectivity is provided through various connectors including CLK IN, CLK OUT, and an AUX I/O port using an HDMI connector (though it’s not for HDMI interface purposes), along with a single-ended, SMB type TRIG connector. These connections enhance the module’s flexibility in various experimental setups.
Furthermore, the NI 5771 features 12 bi-directional channels (comprising 4 PFI and 8 DIO), which are essential for complex data acquisition tasks that require both input and output capabilities. The interface standard is 3.3 V LVCMOS, ensuring compatibility with a wide range of digital logic devices. This specification highlights the module’s adaptability in integrating with various technological setups, making it a highly versatile component for engineers and researchers alike.
