Radio characteristic evaluating apparatus of mobile telecommunication device

An apparatus for evaluating a radio characteristic of a mobile telecommunication device, comprising:

• a base station device of a measuring sample;
• a measured sample terminal;
• a radio mode conversion jig for maintaining a talking state by setting a call between said base station device and said measured sample terminal, for converting transmitting and receiving modes according to a radio characteristic evaluation test, and for attenuating a level of a talking path on the basis of a level setting of the talking path necessary for a receiving test;
• a control terminal device for controlling a call setting of said radio mode conversion jig, the conversion of said transmitting and receiving modes and the level setting of the talking path on the basis of the manipulation of a user according to each measuring item and a specified value, for controlling said measured sample terminal so as to attempt a call, and for managing a result of said radio characteristic evaluation test under said talking state;
• transmitting and receiving testers for measuring transmitting and receiving radio characteristic evaluation tests according to the conversion of said transmitting and receiving modes of said radio mode conversion jig;
• and
• a printer for printing a result of said radio characteristic evaluation test by the control of said control terminal device.

An apparatus for evaluating a radio characteristic of a mobile telecommunication device, comprising:

• a base station to be evaluated according to its transmitting and receiving characteristics;
• a measured sample terminal for making a call to said base station;
• a radio mode conversion jig coaxially connected between said measured sample terminal and said base station device for maintaining a talking state between said base station device and said measured sample terminal, for changing between a transmitting mode and a receiving mode according to a radio characteristic evaluation test, and for attenuating a level of a talking path on the basis of a level setting of the talking path necessary during a receiving test of said base station device;
• a control terminal device for controlling a call setting of said radio mode conversion jig, the changing between said transmitting and receiving modes and the level setting of the talking path on the basis of the manipulation of a user according to each measuring item and a specified value, for controlling said measured sample terminal so as to attempt a call, and for managing a result of said radio characteristic evaluation test under said talking state;
• a spectrum analyzer for measuring transmitting radio characteristic evaluation tests according to the change of said radio mode conversion jig to said transmitting mode;
• a power meter for detecting a loss value in said talking path during the receiving mode and transmitting said loss value to said spectrum analyzer during said transmitting mode;
• a bit error rate meter for measuring a receiving radio characteristic evaluation test according to the change of said radio mode conversion jig to said receiving mode;
• and
• a modulation signal generator for digitally modulating transmitting data generated from said bit error rate meter to cause the base station device, interlinked therewith through the talking path via said radio mode conversion jig, to supply receiving data to said bit error rate meter.
