It may be that no such thing as an "oscilloscope simulation"
exists ... for the following reason:

Given that it is possible to turn a PC into an oscilloscope, 
turning a PC into a "simulated" oscilloscope seems like a 
step in the wrong direction.

The basics of oscilloscope behavior such as triggering
and timebases and voltage-scales are not just simulated by
the PC oscilloscope, they are out-and-out implemented.

The PC oscilloscope will not have as much frequency range
or as much input impedance as the Tek ... but the PC can 
"simulate" the Tek if you just close your eyes to the 
limitations.

Other than high frequency and high impedance, what do you 
want to do that you can't do with a PC oscilloscope?
