Keysight (Agilent) 1130B InfiniiMax Probe, 1.5 GHz

The Keysight (Agilent) 1130B InfiniiMax Probe delivers 1.5 GHz bandwidth for high-performance signal integrity measurements on compatible oscilloscopes. This 10:1 attenuation probe minimizes circuit loading through 1 MΩ input resistance and 11.0 pF input capacitance, enabling accurate characterization of fast signals with minimal distortion. The probe tip capacitance of 0.5 pF (typical) preserves measurement fidelity across digital and analog applications.
