Hi SI people,

When measuring a real PCI bus signal (not 25ohm test load);
Would the starting point of Tprop be for a rising
edge in this case at 0.285Vcc?

Why Tprop isn't measured like in a TDR for example?

Could this be possible in a 'known' system;
I would know exactly which PCI devices are going to be
connected to the bus.
I would have for example;
clock skew of 2ns
setup time 2ns
Tval 2ns

Would Tprop of 24ns in this case be possible
for a 33MHz system?

Br,
Marko
