Abstract

본 발명은 PCB자동조정기에 있어서 특히 무선주파수(RF) 신호의 자동이득제어(AGC) 조정장치에 관한 것으로, 컴퓨터의 제어에 의해 RF AGC를 자동으로 조정하여 정밀도를 향상시켜 품질을 균일하게 하기 위하여 컴퓨터(10)의 GPIB제어부(10c)를 무선주파수신호를 발생하는 RF신호발생기(30)와 DC전압을 측정하는 DVH(40)과 샤시전원공급장치(50)에 연결하고 컴퓨터(10)의 포트확장기(10b)와 RF신호발생기(30)를 프로그래머블 RF신호감쇄장치(20)를 통해 샤시(80)의 튜너(80a)에 접속하고 DVM(40)과 샤시전원공급장치(50)를 각각 샤시(80)의 하치구테스트포인트(TP)점에 연결하고 컴퓨터(10)의 모터제어부(10a)로 모터(60)를 제어하게하여 상기 모터(60)로 샤시(80)의 조정접(80b)을 조정할 수 있게한 발명이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic gain control (AGC) control device for a radio frequency (RF) signal in a PCB automatic regulator. The GPIB control unit 10c of the computer 10 is connected to the RF signal generator 30 generating the radio frequency signal, the DVH 40 measuring the DC voltage and the chassis power supply 50, and the port of the computer 10. The expander 10b and the RF signal generator 30 are connected to the tuner 80a of the chassis 80 through the programmable RF signal attenuator 20, and the DVM 40 and the chassis power supply 50 are respectively connected to the chassis ( 80 is connected to the lower inlet test point (TP) point, and the motor control unit 10a of the computer 10 controls the motor 60 so that the motor 60 adjusts the adjustment contact 80b of the chassis 80. It is an invention that can be adjusted.
