Network Analyzer

[Nino_Brown]

Hi Everyone,

I'm new to Multisim and these forums. I was hoping somebody could help me,  I am trying to measure the s-parameters of this circuit I'm working on, but I can't figure out how to connect the network anaylzer. I tried reading the user guide but it's not much help, I have tried connecting it several different ways, and I get different results everytime.

I'm not sure if this matters but R1, R2 and C3 are the load. The rest is the matching network, and I want to measure the reflected power. 

Thanks In Advance

Hi Nino, 

I'm Chiara, an AE with NI UK.

I found this previous forum which seems to suggest an answer to your question: http://forums.ni.com/t5/Circuit-Design-Suite/How-do-you-connect-virtual-Network-anaylzer-in-a-two-po...

Hope this helps!

Best wishes,

Hi,

Thanks for the input, I had read that thread before but I don't undetrstand it, I'm not sure what a directional coupler is, and which ports I need to connect and where. But I appreciate the help.
