Hi!

For those interested in the AS6500 chip, I have posted my comparison measurements with the TDC7200.

See https://github.com/dorsic/as6500/blob/main/TDC7200_comparision/README.md for more details.

That setup (depending on details such as TDC triggering threshold, risetime, amplitude, source impedance and termination impedances) seems unlikely to guarantee clean incident wave triggering of the TDCs.
A setup with cleaner waveforms at the TDC inputs is desirable.
