The HP/Agilent 70900A Local Oscillator Module is a plug-in component for the HP/Agilent 70000 series modular measurement systems that generates a swept local oscillator signal from 3.0 GHz to 6.6 GHz for frequency conversion and signal analysis. The module functions as the system master controller, processing video signals and managing measurement firmware while integrating with mainframes and displays via the Modular System Interface Bus (MSIB) and GPIB interfaces.
Technical Specifications
• Frequency Range: 3.0 GHz to 6.6 GHz swept LO output
• Memory: Minimum 32 KB for Data Logging Parameters (DLPs)
• System Integration: Operates within HP/Agilent 70000 series modular spectrum analyzer mainframes
• Control Interfaces: Module address and control switches for system coordination
• Firmware Compatibility: Supports firmware version date code 891102 or later; compatible with HP 70860A High-Speed Controller Board Upgrade Kit
– Key Features
• Swept local oscillator generation for frequency conversion
• Video signal processing capability
• Master controller functionality for spectrum analyzer operation
• Embedded system firmware for measurement control and data output
• Static-protected plug-in module design with hex-nut latch securing mechanism
• Power and cooling supplied from system mainframe
– Typical Applications
• Frequency conversion in RF and microwave measurement systems

– Compatibility & Integration
The 70900A integrates with HP/Agilent 70000 series mainframes including the 70001A mainframe and 70004A color display. Communication occurs via MSIB for high-speed digital control between modules and displays, and GPIB for external computer control and instrument communication. Programming code maintains compatibility with the HP 8566B spectrum analyzer. Rear-panel cable connections follow specifications detailed in the Installation and Verification Manual. Removal and reinstallation require loosening the hex-nut latch and observing static discharge precautions.
