[SCM] RLC

Description: 本文所设计的系统是基于AT89C52单片机控制的简易RLC测试仪。为了充分利用单片机的运算和控制功能，方便的实现测量。把参数R、L、C转换成频率信号f，然后用单片机计数后再运算求出R、L、C的值，并送显示。转换的原理分别是RC振荡电路和电容三点式振荡电路。为了比较准确的测试而频率的计数则是利用等精度数字频率计完成。然后再将结果送单片机运算，并在LED显示器上显示所测得的数值。通过一系列的系统调试，本测试仪到达了测试标准。经过测试， -In this paper, the system designed is based on AT89C52 single-chip microcomputer to control a simple RLC tester. In order to take full advantage of single-chip computing and control functions to facilitate the realization of measurement. The parameters R, L, C converted into frequency signal f, and then use the single-chip counts obtained after the operator R, L, C values, and sent to display. The principle of conversion is the RC oscillator circuit, respectively, and three-point oscillator circuit capacitance. In order to test more accurate frequency count is the number of frequency of use of complete accuracy. Then send the results of single-chip operation, and LED display shows the measured values. Through a series of system debugging, the tester arrived at the testing standards. After testing,

[Internet-Network] ICtester

Description: The chip tester verifies the functionality and timing of a variety of 7400 series integrated circuits. Students taking Digital Logic Design Lab, Use these chips often in their laboratory. The IC to be tested should be placed on the ZIF socket and the Microcontroller prompts the user to enter the IC number of the chip to be tested. After entering it the microcontroller will check the IC as per the truth table of the IC which is stored in its ROM. It will check each aand every pin of the IC and produce the Output detaily. Like "Gate 1 is good", "Gate is Bad", "Counter 1 is Good" etc The Block diagram of the project is given below for reference

[Other] COLT-parameter-ADSL-Tester

Description: 大家都知道，ADSL 对线路的要求是很高的，如果安装过ADSL 的，都会有这种体会：外线人员把线路一直由局端机房跳通到用户端，就可以回单完工。然后由技术人员到由户端把设备接好并装好软件，这时候才发现设备连不上或者能连上但经常断线，又或者连上后速度很低（给人的感觉）等种种原因使得用户不签收，技术人员当然就不能回单完工了。只能又把外线人员叫来换线，直到找出好的线对时，ADSL 才能正常工作，装机人员才能收工。在装机时限越来越苛刻的今天，很多ADSL 装机人员都配备了ADSL 测试仪COLT-250。在安装ADSL 时，只需在用户端接上COLT-250，就能马上看到刚才跳的线对的各种参数，很直观地知道该线对能否给用户装ADSL 设备。-As we all know, ADSL on the line requirement is very high, if installed ADSL, and will have such experience: Who has been outside the lines jump from the central office through to the client to connect back to a single completed. And then by the technical personnel to the client The device plugged in and installed the software, this time only to find Rom or can be connected to the equipment but often disconnected, or connected after the fast Very low (the feeling), etc. so the user does not sign for various reasons, of course, technical staff can not return to a single schedule. Only Who again called for an outside line, until you find a good line on time, ADSL to work correctly, installed officers to call it a day. Installed more and more demanding in today s time, many officers are equipped with ADSL installed ADSL Tester COLT-250. In ADSL installation, just in the user termination on COLT-250, you can immediately see just jump the line on the various parameters, it is Intuiti
