Description
The NI-5761 is a high-performance PXI Reconfigurable FPGA Digitizer, with a part number of 747670-01. This model is designed to cater to demanding applications requiring high-speed data acquisition and real-time signal processing. It is capable of a sampling rate of 250 MS/s and offers a bandwidth of 500 MHz, ensuring the capture of high-frequency signals with precision.
The digitizer boasts a resolution of 14-Bit, providing detailed signal representation for accurate analysis. Users can choose between two configurations based on their application needs: the AC-coupled (781287-01) and the DC-coupled (781287-02) options, allowing flexibility in signal acquisition.
Equipped with 4 Simultaneously Sampled Channels, the NI-5761 enables the simultaneous acquisition of multiple signals, enhancing data throughput and system efficiency. Additionally, it features 8 General Purpose digital I/O channels for versatile interfacing with external devices and systems.
The connectivity options include 1 AUX I/O, 4 LEDs for status indication, 1 CLK IN for external clock signals, 1 TRIG for external triggering, and 4 Analog Input connectors (CH 0, CH 1, CH 2, CH 3, CH 4), ensuring comprehensive interfacing capabilities. The sample clock operates at a 250 MHz, fixed frequency synthesizer type, while the reference clock is set at 10 MHz.
For systems requiring synchronization with an external clock, the NI-5761 is compatible with external clock sources. This compatibility is facilitated through the CLK IN connector or the IoModSyncClock, with the CLK IN connector being of the SMA, 50 Ω, AC input coupling type. This feature allows users to integrate the digitizer seamlessly into timing-critical applications, ensuring precise synchronization across multiple devices.
