Agilent/Keysight 1165A

The Agilent/Keysight 1165A is a miniature passive probe engineered for precision electronic measurements across general-purpose oscilloscope applications. Operating at a 10:1 attenuation ratio, it delivers up to 500 MHz bandwidth performance and integrates with Agilent Auto Probe interfaces for automatic oscilloscope configuration.

– Technical Specifications

• Attenuation Ratio: 10:1
• Bandwidth: Up to 500 MHz
• Input Resistance: 10 MΩ (DC)
• Input Capacitance: 12–14 pF
• Maximum Input Voltage: 300 V (DC + peak AC) CAT II
• Cable Length: 1.5 m
• Probe Type: Miniature passive

– Key Features

• Kevlar-reinforced cable construction resists mechanical stress and flexing during extended use
• Durable probe hook withstands repeated connection cycles
• Compact form factor suits confined test points and dense circuit layouts
• Input capacitance tunable within 12–14 pF compensation range
• Compatible with oscilloscopes rated to 600 MHz bandwidth

Note: At frequencies exceeding 100 MHz, the input capacitance of high-impedance passive probes can significantly impact measurement accuracy. Users should verify oscilloscope compensation settings for optimal performance in high-frequency applications.

– Typical Applications

• General-purpose digital and analog circuit measurements
• Voltage monitoring in power delivery and signal integrity testing
• Hardware debugging and system-level characterization
• Production and field service measurements

– Compatibility & Integration

Fully compatible with Agilent/Keysight InfiniiVision 7000 Series, Infiniium 8000 Series, and 54830 Series oscilloscopes. The Auto Probe interface eliminates manual configuration, allowing the connected oscilloscope to automatically recognize probe parameters and adjust input settings accordingly.
