摘要:現代化電子儀器設備之中的晶振各式各樣,種類很多,每一個晶振的作用都很重要!那么我們怎么知道晶振是否在正常工作呢?怎么檢測晶振的好壞呢?...

  主板上可以看到各種各樣類型的晶振,它們安靜的坐落在適合自己的位置上,辛勤的勞動,默默地堅守自己的崗位。晶振小小的個頭,大大的能量。但是晶振工作時間久了,身體也是會累垮的,這時候晶振的體檢工作就非常重要了。

如何檢測晶振是否在正常工作?如何辨別晶振的好壞?相關問答:

問題:石英晶體振蕩器不起振

回答:正反饋通道基本上不存在,基極輸入的交流電壓都被旁路電容C3短路掉了。要么就是接觸不良,晶振已經壞了

問題:澳门百家乐攻略晶體振蕩器是不是晶體管震動的

回答:不是,只是起放大和開關作用,主要起振蕩的是電感、電容和晶振元件,如電容三點式振蕩器等等。。。。

問題:晶體振蕩器怎么樣測其好壞?

回答:測量晶體振蕩器兩腳的對地電壓,若兩點電壓相差1V多,說明振蕩器基本正常。如果手頭有示波器就簡單了,可以看看波形。

問題:鐘表需要什么石英晶體振蕩器

回答:由于石英晶體在壓力下產出的電場強度很小,這樣僅需很弱的外加電場即可產生形變,這一特性使壓電石英晶體很容易在外加交變電場激勵下產生諧振。其振蕩能量損耗小,振蕩頻率極穩定,這些再加上石英優良的機械、電氣和化學穩定性,使它自40年代以來就成為石英鐘、電子表、電話、電視、計算機等與數字電路有關的頻率基準元件。

問題:晶體振蕩器有什么作用?

回答:澳门百家乐攻略晶振在應用具體起到的作用,微控制器的時鐘源可以分為兩類:基于機械諧振器件的時鐘源,如晶振、陶瓷諧振槽路;RC(電阻、電容)振蕩器。一種是皮爾斯振蕩器配置,適用于晶振和陶瓷諧振槽路。另一種為簡單的分立RC振蕩器。
