Dave,
What was said about 150 posts back was that we don't need an actual TDR
function - anyone can figure out the length using the Logmag function,
The TDR gives you a *lot* more than just length. See
You can¡¯t assume anything about the velocity factor either - it¡¯s far from
a constant, whereas with TDR you can measure an actual impedance - no need
to know the diameter of the coax or the relative permittivity.
Cheers,
Larry
