Yes, That's what I meant.

I thought that everyone would understand.

I tried that also, ("SYSTEM:OPTION:UNINSTALL") just times out with "Remote command is incorrect!" appearing on DP832 screen.
The other thing I notice is that V1.06 has 30 calibration DAC points, V1.08 has only 29 points.
I think there is something sinister going on here, hope to be proved wrong |O

Thanks!

This is for 0 cm, 1 cm, 5 cm and 10 cm stubs, using vacuum (air) as dielectric. So this should correspond to about 0 cm, 0.5 cm, 2.5 cm and 5 cm stubs for real world dielectrics.

Very interesting. What program did you use for this?

Text added!  :)

Well this is pretty much theory. This is the case if the coax cable impedanz is perfectly 50ohm which is not the case and if the Transmission line inside is perfectly and if the Terminator is perfectly 50ohm ... I would worry more about tolerances than this line theory
