HP / Agilent 41800A

The Keysight Technologies, Inc. 41800A active probe provides high input impedance from 5 Hz to 500 MHz. The 41800A is a valuable tool when used with a network and spectrum analyzer for circuit signal analysis. The 41800A improves your circuit design and evaluation for audio, video, HF, and VHF bands. The low input capacitance offers probing with negligible circuit loading, making it effective for precise in-circuit measurements.

For Both Spectrum and Network Analysis

The 41800A can be used with a spectrum analyzer to evaluate the quality of circuits by measuring spurious level, harmonics, and noise. The active probe can also be used with a network analyzer to perform gain, phase, and group-delay measurements at the circuit-level.

Retractable Metal Sleeve for Protection

In addition to excellent performance, the 41800A also has a design to protect the probe tip. The probe has a retractable metal sleeve which protects the probe tip from a physical damage when not used and also from electro-static discharge (ESD) damage.

Compatible with Keysight, Agilent, and HP Network and Spectrum Analyzers

The 41800A is directly compatible with a wide variety of current model and legacy network and spectrum analyzers. These Keysight analyzers have the probe power supplied from the front panel. In addition, you can use the Keysight 11899A probe power supply with other analyzers that don’t have a compatible power supply for the 41800A.
