UNIT...
This subsystem defines default units for all SCPI commands and queries implemented by the network
analyzer.
UNIT:LENGth <unit>
Defines the default unit of length. The command affects all SCPI commands defining a parameter with a
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
