Title:
TERMINAL TESTER
Document Type and Number:
Japanese Patent JP3833643
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that, when two radio communication terminal testers are prepared, and control and test a process that a call is originated from a mobile terminal and terminated at the other terminal, using call controllers and a synchronizer circuit, the measurement error cannot be corrected to result in worth measurement accuracy because of separated analog circuits and digital circuits, and it is difficult to measure while synchronizing the two call controllers.
SOLUTION: The terminal tester for testing performance comprises an RF circuit for transmitting/receiving RF signals via a distributor, an inverse diffusion coder for inversely diffusing the received RF signals with inverse diffusion codes to output decoded common channel signals and individual channel signals, a diffusion coder for coding and diffusing these signals with coding codes, a call controller for controlling them, and a decider for comparing and deciding output signals from the inverse diffusion coder with test signals given to the diffusion coder.
