Title
(EN) SIGNAL SUPPLY DEVICE
(FR) DISPOSITIF DE GÉNÉRATION DE SIGNAL
(JA) 信号供給装置
Abstract
(EN)
A signal supply device (50; 50a) is provided with: a frequency adjustment unit (21, 22); a modulation unit (23); an amplification unit (24); a current measurement unit (25) that measures an antenna current; a frequency setting unit (27) that sets a use frequency to be used as a carrier wave frequency; and a control unit (21). The control unit measures an antenna current every time the carrier wave frequency changes while performing a test signal supply process for changing the carrier wave frequency within a prescribed frequency range which is the resonance frequency range of an antenna, modulating the carrier wave on the basis of a test signal, and amplifying the modulated carrier wave so as to supply, to the antenna, the resultant wave as a signal to be outputted. The frequency setting unit sets, as the use frequency, a frequency corresponding to an antenna current of a large one, among antenna currents measured during performance of the test signal supply process.

La présente invention concerne un dispositif de génération de signal (50; 50a) comprenant : une unité de réglage de fréquence (21,22); une unité de modulation (23); une unité d'amplification (24); une unité de mesure de courant (25) qui mesure un courant d'antenne; une unité de réglage de fréquence (27) qui définit une fréquence d'utilisation à utiliser en tant que fréquence d'onde porteuse; et une unité de commande (21). L'unité de commande mesure un courant d'antenne chaque fois que la fréquence de l'onde porteuse change tout en effectuant un processus de génération de signal de test pour changer la fréquence de l'onde porteuse dans une plage de fréquences prescrite qui est la plage de fréquences de résonance d'une antenne, moduler l'onde porteuse sur la base d'un signal de test, et amplifier l'onde porteuse modulée de façon à fournir, à l'antenne, l'onde résultante en tant que signal à délivrer. L'unité de réglage de fréquence règle, en tant que fréquence d'utilisation, une fréquence correspondant à un courant d'antenne important, parmi des courants d'antenne mesurés pendant l'exécution du processus de génération de signal de test.

信号供給装置(50;50a)は、周波数調整部(21、22)と、変調部(23)と、増幅部(24)と、アンテナ電流を測定する電流測定部(25)と、搬送波の周波数として使用される使用周波数を設定する周波数設定部(27)と、制御部(21)と、を備える。制御部は、試験信号供給処理であって、アンテナの共振周波数の範囲として所定の周波数範囲内において搬送波の周波数を変化させ、試験信号により搬送波を変調し、変調後の搬送波を増幅させて出力対象信号としてアンテナに供給する試験信号供給処理を実行しつつ、搬送波の周波数が変化する毎にアンテナ電流を測定し、周波数設定部は、試験信号供給処理が実行中に測定されたアンテナ電流のうち、大きい側のアンテナ電流に対応する周波数を、使用周波数に設定する。
