physical unit that is related to a length, in particular:
Length offset parameters ([SENSe:]CORRection:EDELay...)
Parameters of the distance-to fault measurement
(CALCulate<Chn>:TRANSform:DTFault...)
Derived units, e.g. the attenuation per unit of length defined via
CALCulate<Ch>:TRANsform:DTFault:DEFine
Stimulus values for limit lines and ripple limit lines for the distance-to fault trace (e.g.
CALCulate<Chn>:LIMit:DATA)
<unit>
METer– metric units
