If you are not agree please show it on a ADS smith chart AND Not simply speaking and taking time. TAKE A LOOK AT IT exactly! :) I've upload it with a better resolution I've Showed it exactly on the picture, Impedance is obviously visible on the chart, forget about the marker, I Plotted data is a reflection coefficient, Γ not impedance, z. Simply you can not understand basic things including Smith chart correctly. It is reflection coefficient not impedance.ĪDS plot any complex value, aho(=Γ), marker calculates and shows z. I think you've just confused your self with your new names :) Simply we give this to ADS and it shows us its corresponding normalized impedance. Then we can have our ref coef = (z-1)/(z 1) = 0.2 j 0.4 Our normalized Impedance gonna be z= 1 j Every complex concept consist of very simple things. Surely you are yourself stuck with it a little. You'r just naming normalized Impedance aho! Your misunderstandings resembles to the following. If you plot any complex value as reflection coefficient and place marker on it, marker calculates and shows impedance value from reflection coefficient. Marker shows values, (1 aho)/(1-aho) from plotted any complex value, aho. Rather ADS draws any complex value, aho simply. But yes, it is required to interpret the Smith chart if you want to read absolute impedance values.ĪDS does not draw the normalized impedance. The reference impedance information is not required for drawing. You already have reflection factor and that is what ADS is drawing. Surely see and understand my first response. You can not understand axises of smith chart at all. I really was and am missing basic concepts. My mistake was that I expect it to draw the exact input value on the chart. It is true that smith chart is the ref coefs ( reflection coefficients) and smith chart in ADS will assume any input value as ref coef AND " will draw the normalized Impedance that will result in the input ref coef ". Unfortunately it is not simply drawing any complex value that we are introducing as input! try it once. If Zload is normalized, Gamma is (Zload-1)/(Zload 1). I assumed your Zload is unnormalized, so I calculated Gamma with Rref=50. Plotted data is located at horizontal=boke and veritical=kasu. I don't understand what ADS is drawing? Is it drawing ref coeffs? so where did it get the characteristic impedance? I am not sure whether this helps you are not but I have plotted impedances in Matlab, which has RF toolbox. Smith chart is a plane of reflection coefficient not impedance. I know that I'm missing an important concept including normalizing and characteristic Impedance. My desired chart which is presented in one of keysight's tutorials must be like : I want to plot simple array of data in ADS smith Chart ( On display page, I\m not talking about ADS smith Chart utility).
