That's qhat I thoguht (and while my 'scope would give up at 1GHz (well,
it is over 40 years old...) I dow own a frequency counter that goes way
beyond that. Yes it's old. It contains no ICs (and no valves other than
the display nixie tues, it's all discrete transistors). HP, of course :-)
So I ask again. What clock signal is this 2GHz refering to? And does it
relate in any way to some signal I can actually put a probe on?
OK, so if I buy a 2GHz PC, what signal is that
2GHz describing? And
how does it relate to signals I can measure?
You can poke and prod all you want, but I believe that you won't find
a pin on a Pentium 2GHz x86 with a 2GHz waveform on it. Just goes to show you how meaningless clock speed is.
Well I have long supsected that :-)
