Note: Make sure to select a sufficient number of sweep points and a suitable fre-
quency span before you start the calibration. Otherwise the measurement may yield
inaccurate results.
Use
Auto Number of Points to let the firmware assist you with this.
Fault Limit Check
Enables/disables checking the current "Distance to Fault" trace for spikes above the
given
Fault Limit (red line).
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 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 9.9.4.2, "Define Limit Lines Dialog" ,
on page 402).
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 9.9.4.2, "Define Limit Lines Dialog" , on page 402)
●
This field is only enabled, if Fault Limit Check is active.
