The Agilent/Keysight 86601A is an RF section module that expands the frequency coverage of 8660A and 8660C signal generators into the lower frequency spectrum. This plug-in unit enables signal generation and testing from 0.01 MHz to 110 MHz, addressing applications requiring precise low-frequency stimulus and measurement capabilities.
Technical Specifications
• Frequency Range: 0.01 MHz to 110 MHz
• Base Unit Compatibility: Agilent/Keysight 8660A and 8660C signal generators
– Key Features
The 86601A extends the operating range of compatible 8660-series generators into the VLF through low-HF bands. The module integrates directly with its host instrument, providing continuous frequency coverage across the specified range without external interconnection complexity.
– Typical Applications
• Low-frequency signal generation and characterization
• RF circuit testing in the 0.01–110 MHz band
• Receiver sensitivity and selectivity measurements
• Audio and subsonic frequency stimulus
– Compatibility & Integration
Designed exclusively for the 8660A and 8660C platforms, the 86601A module plugs into the host generator to become an integral part of the signal source. No external power supplies or auxiliary equipment are required for operation.
– Product Status
This module is classified as obsolete and is no longer manufactured or sold by Keysight. Legacy units may remain eligible for repair and calibration services through authorized Keysight service channels. Complete technical documentation—including the original 1979 Operation and Technical Manual and Operating + Service Manual (86601-90027)—remains available to support existing installations.
