Description
The NI-5761 is a model within the PXI Reconfigurable FPGA Digitizers category that is designed to provide high-speed and accurate data acquisition capabilities. This model comes in two part numbers depending on the coupling type; the DC-coupled version is identified by part number 781287-02, while the AC-coupled version carries part number 781287-01.
It boasts an impressive sampling rate of 250 MS/s (Mega Samples per second), allowing for rapid data capture. This is complemented by a bandwidth capacity of up to 500 MHz, ensuring that a wide range of signals can be accurately processed. With a 14-Bit resolution, the NI-5761 provides precise digitization of analog signals, making it suitable for applications requiring high fidelity.
This digitizer is equipped with 4 simultaneously sampled channels, enabling the acquisition of multiple signals at once. It also features 8 general purpose digital I/O channels, offering flexibility for interfacing with other devices or systems.
The front panel of the NI-5761 is designed for ease of use and connectivity, including 1 AUX I/O, 4 LEDs for status indication, a CLK IN for external clock signals, a TRIG for external triggering, and 4 analog input connectors (CH 0-3) for signal inputs.
An integrated 250 MHz sample clock with a fixed frequency synthesizer type ensures precise timing for sample acquisition, while a 10 MHz reference clock provides a stable frequency reference for the system. The NI-5761 is compatible with external clocks through its CLK IN connector or through the IoModSyncClock, offering flexibility in synchronization with other systems. The CLK IN connector is an SMA, 50 Ω, AC input coupling, and the external trigger connector is an SMA, DC input coupling, ensuring compatibility with a wide range of external devices.
