Note that the fault limit is handled like any other limit line. When "Fault Limit Check" is
enabled, the current "Fault Limit" forms a new upper line segment replacing other pre-
viously defined limit lines (see
Chapter 10.9.4.2, "Define Limit Lines dialog" ,
on page 435).
Remote command:
CALCulate<Chn>:TRANsform:DTFault:PEAK:STATe
Fault Limit
Determines the level above which peaks in the active "Distance to Fault" trace are con-
sidered as faults.
The fault limit is defined relative to the 0 dB-line in the test diagram, i.e. the peak
response value for total reflection after proper calibration.
Note:
●
When the "Fault Limit" is modified, the new "Fault Limit" replaces other limit lines
(see
Chapter 10.9.4.2, "Define Limit Lines dialog" , on page 435)
●
This field is only enabled, if Fault Limit Check is active.

10.6.7.2 Available Cable Types... dialog
The "Available Cable Types..." dialog allows you to display predefined and user-
defined cable types and to add/modify/delete user-defined cable types.
Among the predefined cable types, there is an ideal air line (with a relative permittivity
of 1, a corresponding velocity factor of 1, and zero attenuation) and a wide range of
standard cable types.
