射频单元转换器介绍 RF Unit Converter Introduction
该工具是电压和功率的单位转换器。有一个阻抗输入允许功率和电压之间的关系。
This tool is a unit converter for voltage and power. There is an input for impedance that allows the relationship between power and voltage.
欧姆 Ohm
电阻或阻抗的单位。电阻可以定义电压和电流以及电压和功率之间的关系。根据欧姆定律，电压和电流的关系是：
The unit for resistance or impedance. Resistance can define the relationship between voltage and current and voltage and power. Based upon ohms law the voltage and current relatinship is:
and power is
Vpeak - Peak Voltage
交流信号的峰值电压是峰值幅度。Peak voltage of an AC signal is the peak amplitude.
Vrms - RMS Voltage
均方根电压或 Vrms The Root Mean Square Voltage or Vrms is:
μV - Microvolt (RMS)
该值是以微伏为单位的 RMS 电压。This value is the RMS voltage in microvolts.
μV EMF
这个值是微伏，没有端接或负载。This value is microvolt with no termination or load.
μV PD
这个值是带有负载的微伏。当信号具有匹配的负载时，负载两端的电压会下降一半。该值与 uV 值相同，单位只是明确定义为有负载。This value is microvolt with with a load. When a signal has a matched load then half of the voltage is droped across the load. This value is the same value as uV, The unit is just explicitly defined as having the load.
dBuV - dB Microvolts RMS
这个单位是 RMS 微伏的分贝。This unit is the decibel of RMS microvolt.
dBuV EMF - dB Microvolts EMF
这个单位是 EMF 微伏的分贝。This unit is the decibel of EMF microvolt.
dBuV PD - dB Microvolts PD
这个单位是 EMF 微伏的分贝。This unit is the decibel of EMF microvolt.
