Abstract

카운터와 오실로스코프등의 계측기에 튜너에서 발생된 신호를 자동으로 검출 및 입력하여 그 계측결과에 따라 제어부로 제어하여 튜너를 자동 조정하는 튜너의 자동 검사장치 및 그 제어방법에 관한 것이다.The present invention relates to an automatic inspection apparatus for a tuner and a method for controlling the tuner which automatically detects and inputs a signal generated by the tuner to a counter and an oscilloscope, and controls the controller according to the measurement result.

자동 입력장치를 구동하여 튜너에 연결한 후, 채널 주파수 신호를 자동 입력 장치를 통해 튜너에 입력시키고 지그부를 통해 IF 주파수를 검출하여 카운터로 측정하고, 그 측정치를 규정치와 비교하여 튜닝전압을 조정하여 규정치로 맞추고, 튜너검사신호를 발생시켜 상기 자동입력 장치를 통해 튜너에 입력하고, 상기 튜너의 테스트포인트에서 그 결과 신호를 검출하고 그 결과 신호를 계측하여 규정치가 아닌 경우 불량을 표시하고 규정치인 경우 다른 채널로 변경하여 상기 채널주파수 입력과정부터 반복한다.After driving the automatic input device and connecting it to the tuner, input the channel frequency signal to the tuner through the automatic input device, detect the IF frequency through the jig part, measure it with a counter, and adjust the tuning voltage by comparing the measured value with the specified value. Adjust the threshold value, generate a tuner test signal, input it to the tuner through the automatic input device, detect the result signal at the test point of the tuner, measure the result signal, and display a defect if it is not the specified value Change to another channel and repeat from the channel frequency input process.
