@nprofile1q... The limiting factor in my case ended up being slew rate. I suspect that using fast RF schottkies for both the sampling gate as I did, and to generate an edge to use as stimulus you may be able to get down to dozens of ps rise time with a small budget. The higher you go, de-embedding the pulse shape gets more difficult though.

Each pin with a small delay-line. I You could take any quanta, with no extra chips, and bring down the quan...
