The Keysight (Agilent) U1818A is a 100 kHz to 7 GHz active differential probe designed for accurate high-frequency in-circuit measurements with spectrum, network, and signal source analyzers. It features a broad bandwidth and a flat frequency response of ±1.5 dB, with a low noise floor below -130 dBm/Hz, ensuring precise low-amplitude signal measurements. The probe is powered directly from compatible Keysight instruments or a benchtop supply.
Ideal for RF analysis, the U1818A supports various probe heads (sold separately) like N5380B, N5381B, N2839A, N5425B, and N5426A for flexible and precise probing configurations.
