Description
The NI-5761 model is a high-performance digitizer with both AC-coupled and DC-coupled versions identified by part numbers 781287-01 and 781287-02, respectively. This device features a substantial sampling rate of 250 MS/s, providing the capability to capture fast-changing signals with high fidelity. Its bandwidth reaches up to 500 MHz, allowing for a wide range of signal frequencies to be accurately measured.
The NI-5761 achieves a high level of precision with its 14-Bit resolution, ensuring detailed signal representation. It can sample 4 channels simultaneously, making it suitable for applications requiring multi-channel data acquisition. Additionally, it is equipped with 8 general purpose digital I/O channels, offering flexibility for various digital signaling needs.
For connectivity, the front panel includes 1 AUX I/O, 4 LEDs, 1 CLK IN, 1 TRIG, and 4 Analog Input connectors (CH 0-3), providing a comprehensive set of interfaces for external control and signal input. The sample clock is an integrated 250 MHz, fixed frequency synthesizer, ensuring stable and precise timing for sample acquisition. A 10 MHz reference clock is also included, supporting synchronization with other instruments or systems.
External clock input is facilitated via a CLK IN connector or IoModSyncClock, with the CLK IN connector being a SMA, 50 Ω, AC Input Coupling type. This provides flexibility in timing synchronization with external sources. The device also supports an external trigger, with the connector type being SMA and supporting DC Input Coupling, allowing for precise control over the sampling process based on external events.
