关于ADS里边的Eqn问题

lZ的头像怎么跟我一样，汗。
ADS里每个函数的用法在help里都有详细的说明，遇到没见过的可以去查询下
equ即equation，表明这是个计算公式

看来要得花时间去了解这些函数了，请问有什么值得借鉴的经验吗？谢谢
PS：这头像很可爱

没啥借鉴的经验，不会的时候看help文档就是最好的经验

ADS里面的公式是自己特定的公式，没有特定的地方，也不能和其他软件通用，只能多看几个公式例子和HELP，慢慢找感觉.

你说的自己特定指的是？

估计意思就是指：这些公式是ADS专门用的

资用功率增益圆：
ga_circle()
Generates an available gain circle.
语法规则Syntax：
y = ga_circle(S, gain, numOfPts, numCircles, gainStep)



Default value for gain is min(max_gain(S)) - {1, 2, 3}
Examples
circleData = ga_circle(S, 2, 51)
circleData = ga_circle(S, {2, 3, 4}, 51) return the points on the circle(s).
circleData = ga_circle(S, , 51, 5, 0.5) return the points on the circle(s) for 5 circles at maxGain - {0,0.5,1.0,1.5,2.0}
circleData = ga_circle(S, , , 2, 1.0) return the points on the circle(s) for 2 circles at maxGain - {0,1.0}
此功能用于在小信号S参数模拟。
函数生成常数资用增益圆源不匹配造成的，圆的定义在指定的增益源反射系数点。
This function is used in Small-signal S-parameter simulations.
The function generates the constant available-gain circle resulting from a source mismatch. The circle is defined by the loci of the source-reflection coefficients resulting in the specified gain.
A gain circle is created for each value of the swept variable(s). Multiple gain values can be specified for a scattering parameter that has dimension less than four. This measurement is supported for 2-port networks only.
If gain and numCircles are not specified, gain circles are drawn at min(max_gain(S)) - {0,1,2,3}. That is, gain is calculated at a loss of 0,1,2,3 dB from maxGain.
If gain is not specified and numCircles is given, then numCircles gain circles are drawn at gainStep below max_gain(). Gain is also limited by max_gain(S). That is, if gain > max_gain(S), then the circle is generated at max_gain(S).
圆方程：

你的Eqn红色的，代表有错误或未定义好。

谢谢，这些我已经解决了，专用的公式表示还不是很熟悉

有些函数的用法还得经常查help文件才会用，毕竟是ADS自己家定义的，和其他软件还是回略有不同。

经常用啦 就记得啦不过对公式的物理意义要理解 具体格式就多看看HELP文档啦
