RADIO TERMINAL, RADIO TERMINAL MEASURING SYSTEM, AND METHOD FOR CONNECTING RADIO MEASURING TERMINAL IN RADIO TERMINAL

摘要

PPROBLEM TO BE SOLVED: To reduce the distribution error of a distributor by making loads of first and second radio machines equal to each other regardless of states of the radio machines if the first radio machine, the second radio machine and a radio property measuring apparatus are connected to the distributor altogether. PSOLUTION: Each of the first and second radio machines includes: a radio measuring terminal to/from which a predetermined signal for radio property measurement is inputted/outputted when measuring radio properties of the present or other radio machine; a receiver circuit; a transmitter circuit; a transmission/reception switching circuit which is switched to a receiver circuit side or a transmitter circuit side to connect the radio measurement terminal to the circuit side to which the transmission/reception switching circuit is switched; and an isolator which is disposed between the transmission/reception switching circuit and the transmitter circuit for passing a signal only in the direction from the transmitter circuit to the transmission/reception circuit. If the present radio equipment is to be turned into standby state for measuring radio properties of the other radio equipment, the transmission/reception switching circuit is switched to the transmitter side to connect the radio measuring terminal to the isolator.
