Power compensation method and frequency power meter with power compensation

The invention discloses a power compensation method and a frequency power meter with power compensation. The method comprises the following steps: S1, acquiring the detection frequency of a frequency detection circuit, the detection temperature of a temperature sensor and the detection power of a power detection circuit; S2, compensating the detection frequency of the frequency detection circuit and the detection power of the power detection circuit according to the detection temperature of the temperature sensor so as to obtain compensation frequency and compensation power; and S3, based on the compensation frequency and the compensation power obtained in the step S2, calculating a compensation value of the compensation frequency according to a frequency-power curve so as to obtain final sampling power. The detection frequency and the detection power are compensated by adopting the temperature value, and the power value is further compensated according to the compensated detection frequency value and the com
