<P>PROBLEM TO BE SOLVED: To easily evaluate reception possibility/impossibility of a transmission signal using a single device, by evaluating an electric power of noise at a point at which the transmission signal is received, in the middle of a transmission path. <P>SOLUTION: A communication performance checker 10 includes an acquisition part 111 which acquires the noise component that affects a transmission signal through a filter circuit 13 from a transmission path 20 used for communication. A calculation part 112 calculates, as a signal/noise ratio, a ratio between a reception limit which is a minimum value of reception power that is predetermined for the transmission path 20 and the electric power of noise component which the acquisition part 111 acquires. A determination part 113 determines reception possibility/impossibility of the transmission signal at a position where the noise component is acquired in the transmission path 20 by comparing a signal/noise ratio calculated by the calculation part 112 with a reference value that is predetermined. <P>COPYRIGHT: (C)2013,JPO&INPIT |
