A specification, in dB, of the relative level at a particular point in a transmission system as referred to a zero transmission level point (0 TPL). Note that the TLP value does not specify the absolute power that will exist at that point, and the unit of TLP specification is not dBm.; 在傳輸系統(tǒng)中的某點(diǎn)與系統(tǒng)的零傳輸電平(0 TLP)點(diǎn)的相對(duì)電平的分貝數(shù)。注意，TLP是以零 傳輸電平點(diǎn)作考點(diǎn)的相對(duì)值，而非功率的絕對(duì)值，而且TLP中是以dB(分貝)為度量單位，而不用dBm(毫瓦分貝)。
