[ADS SNP File] Why Am I not getting the correct S-parameters ?

录入：edatop.com    点击：
Dear Members,

I have exported a Touchstone file (S-parameters) from CST MWS and would like to see the S-parameters in ADS. I used dataset SNP1, but ADS is not correctly showing the s-parameters. What seems to be the problem?

Images attached below.
Kindly assist...

Original CST S-parameters

ADS is showing what you configured: the 1-port S-parameters with the ground pin connected to another 50 Ohm series resistor (your port 2).

To see in ADS what you see in CST, do a 1-port simulation in ADS with the S1P ground pin connected to ground.

Yes.I figured it out now...
