Howdy,
say I have a signal generator that is generating low frequency pulses with =
very quick
rising/falling times, connected directly to my oscilloscope, and (through a=
 BNC splitter)
to a couple of 1 meter long wires (one for signal the other for ground), op=
en for now.

I can see a nice waveform, which looks as it should.

Now I add a capacitor to the end of the 1 meter cable (not a coaxial cable,=
 just 2 wires),
and of course the waveform will look distorted, because the capacitor is lo=
ading the 50 ohm
output of the signal generator.

BUT if I set the 2 Gsps oscilloscope to measure peak, I can see that just a=
fter the rising
and falling slopes, now that I have added the capacitor there have appeared=
 voltage spikes.

It doesn't surprise me, but what I cannot be 100% sure of is if these spike=
s are due to
transmission line effects (probably they are), or by inductive effects (of =
the cable and/or
of the capacitor)?

Cheers,
Mario
