<P>PROBLEM TO BE SOLVED: To provide a transmission power measurement of a radio transmission device which can reduce consumption power effectively. <P>SOLUTION: A transmission power measuring device measures transmission power by sampling in a sampling section set to be shorter than a valid data section of a radio frequency signal. Then, the sampling starting point in each valid data section is some point from the sampling point next to the former sampling starting point to the sampling point next to the former sampling finishing point in relative view of the valid data section starting point as a reference. The transmission power measuring device equalizes the sampling value in each valid data section by the sampling number in each valid data section, equalizes the average value among the multiple valid data sections to output it as transmission power, and attempts to reduce consumption power while reducing scattering of transmission power by having an active mode in each sampling section and a sleeping mode changed from the active mode in other parts than each sampling section. <P>COPYRIGHT: (C)2012,JPO&INPIT |
