The Keysight N5382A InfiniiMax II is a 12 GHz differential probe head engineered for high-speed signal measurement on densely packed circuit boards. This browser-type probe delivers ultra-low input capacitance and maintains signal integrity across demanding test environments. Steel wire leads with adjustable span (0 to 2 mm) provide Z-axis compliance and flexible access to hard-to-reach test points, supporting both hand-held and probe holder configurations.
Technical Specifications
• Bandwidth: 12 GHz specified; 13 GHz typical when used with InfiniiMax II probe amplifiers such as the DSO81304A or DSO91304A
• Differential Input Capacitance: ≤ 210 fF
• Lead Configuration: Steel wire with variable span from 0 to 2 mm (8 to 130 mils)
– Key Features
• Browser probe head design optimized for differential signal measurement
• Adjustable lead span enables probing in confined spaces and tight component spacing
• Low parasitic capacitance preserves signal fidelity in high-frequency applications
• Compatible with standard probe amplifiers and oscilloscope platforms
• Includes replacement lead wires
– Typical Applications
