HSDD-20-14 QUCS lab The TDR

 

  • This is an optional lab and is NOT one of the required labs for this semester.
  • It does most of what is done in the ADS lab, but with a free simulation tool, QUCS.
  • It is remarkable what can be done with a free version of a SPICE simulator
  • A simple TDR: the structure, extracting instantaneous impedance
  • Different rise times and “impedance”
  • Three transmission lines and masking
  • Reflections from L, C discontinuities and matching to tlines
  • An introduction to “hacking interconnects”
