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
• High-speed differential signal analysis on modern circuit boards
• Signal integrity validation in advanced circuit designs
• Measurement campaigns requiring access to densely routed PCB areas
• Testing with Infiniium oscilloscope platforms across multiple series
– Compatibility & Integration
Works with InfiniiMax II probe amplifiers including the 1168A and 1169A models. The N5382A integrates with Keysight Infiniium oscilloscopes: S series, 90000 X and Q series (via N5442A adapter), 90000A series, 86100D (via N1022B adapter), and 80000B series. Achieves 13 GHz bandwidth when paired with DSO81304A or DSO91304A oscilloscopes.
