The Agilent/Keysight 10438A is a 1:1 miniature passive probe engineered for direct connection to 50-ohm oscilloscope inputs. Part of the modular Keysight 10400 Series, this 1-meter probe delivers low-impedance, high-frequency measurement capability with minimal signal loading. Its narrow, sharp probe tip is optimized for surface mount device probing, while modular construction allows field replacement of tips, cables, and chassis assemblies.
