HP 8481H

The HP 8481H thermocouple power sensor is designed for use with the HP E4418A/B, E4419A/B, 435B, 436A, 437B, 438A, 70100A, and E1416A power meters and provides extraordinary accuracy and stability. The HP 8481H power sensor gives you extremely low SWR and is traceable to the U.S. National Institute of Standards and Technology (NIST). A calibration port is included with the power sensor for calibration with the power meter. This calibration provides traceability to NIST and it eliminates the uncertainties due to temperature changes and the variance in making measurements with different meter/sensor combinations.

Features:

• Excellent SWR for reducing mismatch uncertainty
• Accurate calibration and traceability to NIST
• Accessories included for accuracy optimization and customer convenience
