大家好,小小发现占空比的原理，占空比怎样计算这个很多人还不知道,那么小小来为大家解答以上的问题，现在让我带着大家一起来看看！
1、The time period over which the duty cycle is measured is 100 milliseconds, or the repetition cycle, whichever is a shorter time frame. The worst case (highest percentage on ) duty cycle is used for the calculation. The duty cycle is measured by placing the spectrum analyzer in zero scan (receiver mode) and linear mode at maximum bandwidth (3MHz at 3dB down) and viewing the resulting time domain signal output from the analyzer on a Tektronix oscilloscope. The oscilloscope is used because of its superior time base and triggering facilities.The duty cycle is simply the on – time divided by the period:The duration of one cycle =32msEffective period of the cycle = (1×7+0.5×6)ms=10msDC = 10ms /32ms=0.31Press the PROG ON/OFF button to turn the system On. It will last 1.5s to transmit (Signals).Manual Mode can only be activated when the system is off. Press the Manual ON/OFF button once to activate the Manual mode. The transmission interval is 22ms.。
