As far as I know coax was never used in any delay lines inside Tektronix
The Tek 7912AD here on my desk uses a coax delay line. It really is
just two pieces of coax (one blue, one blue with a black stripe, if I
remember correctly) coiled up at one side of the instrument. I
understand that it's the limiting factor (apart from the vertical
amplifier plugin) on the system's bandwidth, which I've measured in
this case at about 700MHz.
