随着我国移动通讯事业的迅速发展,目前国内移动电话用户已超过1200万户。移动电话手机是一种精密的高科技产品,它是由微电脑控制的无线电发射、接收系统的微型设备,任何数据错误,元件、芯片损坏及工艺原因都会造成手机不能正常工作。手机的维修和故障处理难度很大,需要与之相适应的测试仪器,而此类仪器价格一般在20～40万元。并且对于手机的软件及逻辑电路的故障,这些仪器也无能为力。为寻找一种经济、实用、方便的手段解决手机维修问题,中国邮电工业总公司北京凯尔科贸有限责任公司开发研制了 CL-3020G 移动电话综合检修仪。该仪器采用486以上微机作为工作主机,在硬件检测功能方面包括:逻辑分析仪、数字示波器、数字电压表、
With the rapid development of China’s mobile communications, there are currently over 12 million mobile phone users in China. Mobile phone is a kind of precision high-tech product. It is a microcomputer-controlled radio transmitting and receiving micro-system of equipment. Any data error, component, chip damage and technological reasons will cause the mobile phone to not work normally. Handy phone repair and troubleshooting is very difficult and need to adapt to the test equipment, and such equipment prices are generally 20 to 400000 yuan. And for the phone’s software and logic circuit failure, these instruments are powerless. In order to find an economical, practical and convenient means to solve the problem of mobile phone maintenance, China Post and Telecommunications Corporation Beijing Keer Electronics Co., Ltd. has developed the CL-3020G mobile phone comprehensive maintenance instrument. The instrument uses more than 486 computers as a working host, the hardware detection capabilities include: logic analyzer, digital oscilloscope, digital voltmeter,
