Keysight 41800A Active Probe, 5 Hz to 500 MHz

The Keysight 41800A Active Probe probe offers high input impedance from 5 Hz to 500 MHz. It works with many Keysight spectrum analyzers to evaluate the quality of circuits by measuring spurious level, harmonics, and noise. Low input capacitance offers probing with negligible circuit loading for precise, in-circuit measurements of audio, video, HF and VHF bands.
