As a new development in the field of electronic oscilloscopes a hand - held digital oscilloscope is a truly integrated test tool, with digital storage oscilloscope ( dso ), multimeter and digital ondometer in one easy - to - use instrument
=手持式數字示波表是示波器技術的一個新的發展方向。通過使用大規模集成電路和液晶顯示器，它把數字存儲示波器、數字頻率計、數字萬用表組合在一個手持式儀表體內。A digital automatic ultrasonic inspection system designation is introduced. this system was developed with pc computer and embedded dsp, combining computer software and hardware, ultrasonic nondestructive testing, digital signal processing, embedded rtos and visual instruments technology. it meet the requirements of automatic inspection such as high repetitively frequency and real time alertation
該方案以pc機和dsp系統為核心構成主從機系統框架，以基於虛擬儀器思想的pc機應用程序和基於dsp的嵌入式實時操作系統構成雙重軟體結構，把傳統的超聲波無損檢測技術和先進的虛擬儀器技術、數字信號處理技術、嵌入式實時操作系統、計算機介面通信技術相結合，從而滿足了自動化探傷中1k / s的重復頻率和實時報警的要求。The ? 1 word count error exists in nearly all kinds of digital time and frequency measuring instrument and it affects the instrument ' s measuring precision tremendously
在所有的數字式時間及頻率測量設備中，幾乎都存在著1個字的計數誤差。它的存在，極大地影響儀器的測量精度。Due to the sole - designed of the low voltage startup and power testing, for combined with the other four modules, we built the hardware and software flats, it was also convenient for continued extension. but, if there was different system wanted to combined in this system, we must redesigned all the hardware and software, it was a very hard work and could bring incompatibility. for this instance, the text designed a suit of number discriminating embedding system
但是如果有不同類型的系統也要增加到本系統中的話，就需要重新設計軟硬體，工作量很大，還容易產生不兼容等問題，針對這種情況，本文設計了一套數字識別的電器安全測試嵌入式系統，可以面向多臺儀器裝置，不採用電氣的連接，即是不改變原來的儀器裝置，通過電壓耦合元件攝像頭和視頻捕獲卡從測量儀器的顯示屏幕獲取測試信息，再把信息傳送到原來系統，從而組成了一個新的系統。According to the principle of correlation detection, an automatic measurement system for extinction ratio of polarizer consisted of monochromator and dsp lock - in amplifier and compurer is designed not only to eliminate the influence on measurement accuracy caused by drift of intensity of light source but also to obatain approximate extinction spectrum
摘要基於相干檢測原理設計了一套由單色儀、數字鎖相放大器和計算機聯合使用的透射式偏光鏡消光比智能化測試實驗系統，採用雙頻雙光路分光單探測器接收鎖相放大器分離信號比對法進行源補償測量，克服了光源光強漂移所帶來的影響；實現了可見光區消光比的精確自動測量，而且可以測得近似的消光光譜。Design of simple low frequency digital phase measurement instrument
