ABSTRACT:
A swept microwave power measurement system and method capable of performing accurate high performance absolute power measurements on the fly for integration with a scalar analyzer. The system interpolates a calibration factor of the detector at a given frequency point in the sweep between previously established calibration factors at various predetermined frequencies which are stored in memory and then determines an "apparent" power level of the input signal at a standard frequency. The interpolated calibration factor is applied to the "apparent" power level to determine the "absolute" power level at the given frequency point in the sweep.
