The Agilent/Keysight 70703A is a Local Oscillator interface module engineered for integration into the 70000 Series Modular Measurement System (MMS). This module manages LO signal distribution and routing across multiple MMS modules, maintaining signal integrity and compatibility throughout the system architecture.
Technical Specifications
The 70703A functions as an LO interface within MMS mainframes, accepting local oscillator signals and distributing them to RF and microwave measurement modules. The module connects to the MMS backplane for power delivery, control communication, and signal routing. It accommodates the full range of measurement modules available in the 70000 Series ecosystem, including low-frequency, RF, microwave, and lightwave measurement instruments.
– Key Features
• LO signal distribution and management across MMS modules
• Integration with 70000 Series MMS mainframe architecture
• Backplane connectivity for power and control signaling
• Multi-module interconnect capability via system-defined interfaces
• Signal routing compatibility with modular RF and microwave measurement sections
– Typical Applications
The 70703A supports complex ATE configurations requiring coordinated local oscillator distribution. Common deployments include automated RF and microwave test systems where multiple measurement modules require synchronized or independent LO sources. The module ensures proper signal control and timing across instrument combinations in production test, characterization, and field service environments.
– Compatibility & Integration
The 70703A operates within Agilent/Keysight 70000 Series MMS mainframes such as the HP 70004A Color Display and Mainframe. It interconnects with other MMS modules through the system backplane and dedicated module-to-module cabling. Specific LO routing cables (such as LO OUT to RF section 1st LO IN configurations) may be required depending on system configuration. Module interoperability spans the complete 70000 Series catalog of RF, microwave, and lightwave measurement modules.
