Admittance Smith Chart mirrored!?

Question asked by sxnnp on May 24, 2018


I want to use ADS's smith chart for documentation. I need both the impedance and admittance chart in one plot.

I've attached a screenshot of the smith chart.


If I'm not mistaken the admittance coordinates are wrong. They should be positive in the lower half of the chart and negative in the top half.

For example the Impedance 0+0.2j shows the Admittance 0+j5 according to the diagram but it should be 0-j5.

Why is the diagramm wrong? Is there a way to correct the labeling?


Thank you
