Accurate measurement of the third order intercept pointfor low distortion IC products such as the LT5514 requirescertain precautions to be observed in the test setup andtesting procedure. The LT5514 linearity performance ishigh enough to push the test equipment and test set-up totheir limits. A method for accurate measurement of thirdorder intermodulation products, IM3, with standard testequipment is outlined below.It is also important to correctly interpret the LT5514specification with respect to ROUT, and the impact ofdemo-board transmission-line termination loss whenevaluating the linearity performance, as explained in theLT5514 Datasheet and in Note 1 of this document.

在Multisim 10軟件環境下，設計一種由運算放大器構成的精確可控矩形波信號發生器，結合系統電路原理圖重點闡述了各參數指標的實現與測試方法。通過改變RC電路的電容充、放電路徑和時間常數實現了占空比和頻率的調節，通過多路開關投入不同數值的電容實現了頻段的調節，通過電壓取樣和同相放大電路實現了輸出電壓幅值的調節并提高了電路的帶負載能力，可作為頻率和幅值可調的方波信號發生器。Multisim 10仿真分析及應用電路測試結果表明，電路性能指標達到了設計要求。 Abstract: Based on Multisim 10， this paper designed a kind of rectangular-wave signal generator which could be controlled exactly composed of operational amplifier， the key point was how to implement and test the parameter indicators based on the circuit diagram. The duty and the frequency were adjusted by changing the time constant and the way of charging and discharging of the capacitor， the width of frequency was adjusted by using different capacitors provided with multiple switch， the amplitude of output voltage was adjusted by sampling voltage and using in-phase amplifier circuit，the ability of driving loads was raised， the circuit can be used as squarewave signal generator whose frequency and amplitude can be adjusted. The final simulation results of Multisim 10 and the tests of applicable circuit show that the performance indicators of the circuit meets the design requirements.

為了改進產品性能和兼容性，最新的HDMI compliance test specification (HDMI CTS) V.1.3增加了新的測試內容和定下了更嚴格的標準。大多數現在遞交給HDMI授權測試中心(ATC) 的帶有HDMI功能的電器都將按照HDMI CTS V.1.3 來測試。Analog Devices (ADI) 分別在美國的綠堡(Greensboro，NC), 東京, 臺灣和北京設立了四家預測試中心為客戶提供HDMI CT 測試以縮短客戶產品上市的時間。在本文中我們將討論HDMI CTS V.1.3新增加的一些重要內容。同時我們也將著重總結一些典型測試項目失敗的原因和可能的修改方案。

This algorithm was developed by Professor Ronald L. Rivest of MIT and can be found presented in several languages. What I provide to you here is a C++ derivative of the original C implementation of Professor Rivets. The library code itself is platform-independant and has been tested in Redhat Linux. I ve included the sample code and makefile that I used for the Linux test. The demo, however, was written with Visual C++ 6 on a Windows 2000 platform.

1. 本移植也是從網上Download的，稍微做了一下整理. 移植除了OS_CPU.h,OS_CPU_A.s,OS_CPU_C.C 三個函數外 對中斷專門用了一個函數OS_int_A.s 按其中的規則 寫中斷函數即可 2。應用實例為\ArmUCOS\App\test1\test.mcp,在周立功2104的扳子上 的ram中就可直接運行(code＋data<16K), 注意使用了.a庫文件 (我習慣這么用) 3. 將所有的文件放到D:\ArmUCOS\下,這樣上面的文件能直接編譯 3。若有疑問電zh_lyp@163.com
