Is it with a same setup as used on the worlds many years ago with the use of a scope?
So far I have seen over here only the blinky code is checked and with RPM limiter ESC's there are different blinky codes.

I can't lay my hands on it (there's a ROAR document on this) right now, but I have the recollection that there is an upper limit for the time the motor phase must fire after the sensor is tripped. I think it's 8 microseconds. Zero tolerance (pardon the pun) for firing early. Testing is done with an oscilloscope.
I have tinkered with a field-usable tool for doing this, but too many distractions...
