Abstract: <P>PROBLEM TO BE SOLVED: To simply and precisely measure signal level, in such as way that a user does not have to take into consideration transmission loss in a transmission line for received signal transmission, in a reception-level measuring apparatus which measures the signal level of a received signal received by a receiving antenna.  <P>SOLUTION: In each cable usable as the transmission line used to connect the receiving antenna to the measuring apparatus, characteristics data which expresses losses L1, L2 per cable unit length generated at a time, when signals at frequencies f1, f2 are passed and characteristics data expressing a length CL of the cable are set. When the level is measured, the losses generated at a time, when a signal at a frequency to be measured passes the transmission line are calculated on the basis of the characteristic data on the cable designated by the user, it is added to the measured signal level, and the signal level is corrected so as to be displayed on a display device. As a result, the user can measure the signal level received by the receiving antenna, by only having to read the displayed signal level, without taking into consideration the losses generated in the transmission line 9.  <P>COPYRIGHT: (C)2003,JPO
