Peak and average power for high-power measurements

Keysight thermocouple power sensors deliver precise, reliable power measurements, even in demanding high-power RF and microwave environments. With high power linearity, measurements remain consistent and accurate, even at elevated power levels. Designed to handle high power levels, the sensors are particularly well-suited for applications involving complex, high-power RF signals, where maintaining accurate readings over time can be challenging. With excellent calibration traceability to national standards, these sensors provide confidence in measurement accuracy and ensure compliance in industries such as telecommunications and aerospace. High-power handling and outstanding stability make thermocouple power sensors ideal for long-term, high-power applications that require reliable, robust performance.
