The Anritsu MA2499B is a sensor adapter that enables legacy 10-pin MA Series power sensors to interface with modern Anritsu power meters featuring 12-pin sensor connectors. This adapter bridges a critical compatibility gap, allowing engineers to extend the operational life of existing sensor investments while maintaining integration with current measurement infrastructure.
## Technical Specifications
The MA2499B provides connector adaptation from 10-pin MA Series sensors to 12-pin power meter interfaces. An internal EEPROM stores up to nine independent sets of sensor calibration factor tables, each individually selectable via the power meter menu. The adapter ships with a 12-pin, 38 cm sensor cable and weighs 2 lbs.
## Key Features
• Stores nine calibration factor tables with independent selection capability
• Internal EEPROM preserves calibration data across measurement sessions
• Per-sensor calibration recall eliminates manual entry and reduces setup time
• Direct menu-selectable calibration tables from power meter interface
## Compatibility & Integration
The MA2499B supports older 10-pin Anritsu MA Series power sensors, including the 4700A and 4600A models. It enables operation with Anritsu power meters ML2437A, ML2438A, and ML2430A. The adapter facilitates precise power measurements by maintaining full sensor functionality while accommodating connector architecture differences between legacy sensors and current-generation power meters.
This adapter restores measurement flexibility to setups where sensor inventory predates 12-pin connector standardization, allowing multi-sensor configurations with individual calibration management without requiring sensor replacement or external calibration management systems.
