The NI 5191 is an 800 MHz differential active probe designed by National Instruments for high-speed signal acquisition and analysis. It features a differential input with high common-mode rejection, enabling accurate measurements of small differential signals in the presence of large common-mode voltages. The probe offers a bandwidth of 800 MHz, a low input capacitance of 0.9 pF, and a differential input impedance of 200 k©. It is compatible with NI oscilloscopes and digitizers, providing precise signal fidelity for debugging and validation of high-speed digital and analog circuits. The NI 5191 is ideal for applications requiring low noise and high accuracy.
