Description
The NI-5761 is a high-performance digitizer featuring two distinct part numbers depending on the coupling type: 781287-01 for AC-coupled configurations and 781287-02 for DC-coupled configurations. This device offers a substantial sampling rate of 250 MS/s (Mega samples per second), which is complemented by an impressive bandwidth of 500 MHz. The high-resolution 14-Bit ADC (Analog to Digital Converter) ensures precise data conversion, making it an ideal choice for applications requiring high fidelity.
It supports 4 simultaneously sampled channels, allowing for efficient multi-channel data acquisition. Additionally, it features 8 general-purpose digital I/O channels, providing flexibility for interfacing with other devices or systems. The front panel of the NI-5761 includes 1 AUX I/O, 4 LEDs for status indication, 1 CLK IN for external clock sources, 1 TRIG for external triggering, and 4 analog input channels (CH 0 to CH 4), ensuring a comprehensive set of connectivity options for various applications.
The device boasts an integrated 250 MHz sample clock, which is a fixed frequency synthesizer type, ensuring stable and accurate sampling. For reference timing, a 10 MHz reference clock is included, facilitating synchronization with other equipment. The CLK IN connector is of the SMA, 50 Ω, AC Input Coupling type, while the external trigger connector utilizes SMA, DC Input Coupling, providing versatility in signal acquisition and triggering methodologies.
