FAQs
for RF Power Sensing
The range includes RF power sensors, RF power meters, dedicated RF power standards, and complete RF power calibration systems. Together, these products support direct RF power measurement, reference-grade calibration, and automated verification workflows for a wide variety of RF applications.
Accuracy is achieved through stable sensor technologies such as thermistor-based and calorimetric measurement methods, combined with documented calibration procedures. Traceability is supported through reference standards linked to national metrology practices, helping users maintain compliance, control uncertainty, and document measurement performance.
An RF power calorimeter measures RF power by converting energy into heat and determining power from the resulting thermal change. It is especially useful for high power RF measurement where conventional low-power sensors are unsuitable. Calorimeters are commonly used in calibration labs and high-power test environments because they offer strong accuracy for reference measurements.
Yes, some instruments in the range are designed to measure both forward and reflected power simultaneously. This is valuable for tuning RF generators, checking mismatch conditions, monitoring VSWR-related behavior, and confirming efficient power delivery to the load.
The portfolio spans a broad operating envelope, from low kHz to GHz frequencies and from very low-level RF signals up to multi-kilowatt power levels. This makes it suitable for everything from low-power sensor calibration to industrial and laboratory high-power RF applications.
A 12-month calibration interval is commonly used for RF power sensing instruments, although the appropriate interval depends on usage intensity, quality requirements, and the criticality of the measurement. In demanding environments, users may perform interim checks or more frequent verification to maintain confidence in performance.
