1.相位

S-093H 3BHB009885R0004相位是指时间点在波形周期内位置。除非与其他信号相比，否则谈论单音信号的相位没有任何意思。也就是说，相位是指两个信号之间的波长差的一部分，其值处于0~360度的范围之内。

相位也可用于表达两个频率相同的波形的相应特征之间的相对偏移量。

对于正弦波而言，“相位”具有两层含义：

正弦函数原点处的初始角度，有时也称为相位偏移或相位差

波周期相对于原点已经经过的那一部分

2. 相移

S-093H 3BHB009885R0004相移是指一个物理量的相位中发生的任何变动，或两个或更多个物理量之间的相位差中发生的任何变动。

3.相位差

相位差是指具有相同频率及相同参考时间点的两个波之间的差异，以度或时间单位表示。当频率相同的两个振荡器之间没有相位差时，称为同相振荡器。当频率相同的两个振荡器具有不同相位（即相位差）时，则称异相振荡器。器件的相移范围称为相位范围（度），即无论其配置方式如何，该设备所能提供的相移量只能处于这一范围之内。

4.相位平衡

S-093H 3BHB009885R0004在给定频率范围内，功分器输出端口相位的zui大峰间差。

Step 1: Phase

S-093H 3BHB009885R0004 Phase refers to the position of the time point in the waveform period. There is no meaning in talking about the phase of a monophonic signal unless compared to other signals. In other words, the phase refers to the part of the wavelength difference between the two signals, and its value is in the range of 0 to 360 degrees.

Phase can also be used to express the relative offset between the corresponding features of two waveforms of the same frequency.

For sine waves, "phase" has two meanings:

The initial Angle at the origin of a sine function is sometimes called a phase shift or phase difference

The part of the wave period that has already passed with respect to the origin

2. Phase shift

S-093H 3BHB009885R0004 Phase shift is any change in the phase of a physical quantity, or any change in the phase difference between two or more physical quantities.

3. Phase difference

The phase difference is the difference between two waves with the same frequency and the same reference time point, expressed in degrees or units of time. When there is no phase difference between two oscillators with the same frequency, it is called an in-phase oscillator. When two oscillators with the same frequency have different phases (that is, phase differences), they are called out-of-phase oscillators. The phase shift range of the device is called the phase range (degree), that is, no matter how it is configured, the amount of phase shift that the device can provide can only be within this range.

4. Phase balance

S-093H 3BHB009885R0004 Maximum peak-to-peak difference in the phase of the output port of the power divider over a given frequency range.
