Simulated "Gold Standard" for Time Domain Tuning

Howdy-

We wish to tune a "real" filter using simulated data by loading the simulated S-parameters into a VNA and converting them (S11 & S22) from the frequency to the time domain, allowing us to then follow the procedure outlined in e.g. AN 1287-8.

Is this possible? If so, which VNAs are recommended?

Thanks in advance,

Mark W. Ingalls

With any of the PNA, PNA-X, or ENA analyzers you can load the simulated data in the analyzer in the form of an S2P (touchstone forma) and if you have the time domain option (option 010) on that box, you can perform a time domain transform on the data loaded from the S2P file. There are other ways to do this, but this is the most straight forward and simple approach.

AWESOME! (I thought so, but just wanted to check to be sure.)

Thanks, daras!

just be sure to use band pass mode in time domain.

And if you are planning to use time domain tuning for manufacturing (rather than R&D), shoot me a pm and we should talk about some other advancements.

Dear Dr_joel-

PM sent, because we definitely have production on our minds.

We are also messing about with IFFT(S11(f)) in Agilent's Genesys linear simulator with spotty results.

I have read several of your papers on the topic, but do not feel like I know much yet. I'll keep on it.
