TDR Analysis using Agilent ADS

TDR analysis is one of the most basic and frequently used analysis by Signal Integrity designers. Attached tech note provides step by step method to perform Single Ended and Differential TDR in Agilent ADS using Transient Simulator.

Also, issues with performing TDR analysis on a band-limited S-Parameter file is also discussed.

While ADS provides superior tool for TDR analysis in SP TDR Front Panel utility but that is not discussed in the attached tech note and it shows the basic TDR analysis capability using Transient Simulator.

Happy Designing,

Impulse Response of Frequency Domain Component

If you are running a transient simulation on a frequency domain defined component (such as transmission line, a multi-layer component, or an S-parameter block), how do you know whether ADS convolution engine has given you a right representation of the impulse response of the component?

Can you trust your time domain results? The answer is Yes. This tutorial will show you how to generate impulse response for a frequency domin defined component. The engine will simultaniously provide the Fourier transform of the impulse response — impulse spectrum. You can then compare this impulse spectrum with your original S-parameter data to believe on accuracy of simulations in ADS.

Thanks to my colleague Wenlei Lian for creating such a nice technical document for designers….!!
