The Keysight (Agilent) N8486AQ is a thermocouple power sensor engineered for precision power measurements across the 33 GHz to 50 GHz band. Built-in EEPROM automatically loads calibration factors and sensor characteristics into compatible power meters, eliminating manual configuration and reducing setup errors. The sensor delivers sub-1% power linearity, excellent SWR performance, and NIST-traceable calibration for demanding metrology and high-frequency component characterization in laboratory and production environments.

– Key Features
• Thermocouple technology provides stable, repeatable measurements with high accuracy
• Automatic calibration factor loading via EEPROM reduces operator error and setup time
• NIST-traceable calibration ensures measurement confidence in regulated environments
• Low mismatch uncertainty through optimized SWR performance
• Option CFT maintains backward compatibility with 8480 Series instrumentation
• Torque-critical waveguide flange connection (<3.75 lb-in maximum)
– Typical Applications
• Component and subsystem power characterization at Ka and V bands
• Production testing of high-frequency amplifiers and frequency converters
• Power meter calibration verification and traceability maintenance

– Compatibility & Integration
The N8486AQ integrates with Keysight EPM (N1913/14A, E4418/19B), EPM-P (E4416/17A), and P-Series (N1911/12A) power meters. Option CFT extends compatibility to the Keysight Base Station Test Set (E7495A/B) and maintains SCPI code alignment with 8480 Series equipment. Not compatible with 43x, E1416A, N8262A power meters, 5314x microwave counters, or E7495x base station test sets (except CFT variant with E7495A/B).
