s3p OPEN/SHORT Termination

I have s3p file and want to make 3rd port open or short.

What I thought was cascading 0 ohm resistor to 3rd port of s3p.

But it doesn't work.

How can I do that?

Please help me.

Hello 상욱 이,

Inoder to make third port open or short from the available 's3p' file. follow the steps given below:

1. Create an n-port circuit element by passing the file as argument.
2. Then, create a new circuit object from the obtained nport.
3. Then cascade resistor of zero ohms with port three.

I'm attaching the sample code for your reference:

nobj = nport(S);
ckt = circuit('new');
add(ckt, [1 2 3],nobj)
add(ckt,[3 0],resistor(0))
setports(ckt,[1 0],[2 0],[3 0])
frequency = linspace(1e9,2e9,100);
sparameters(ckt,frequency)
