Background information
Refer to Chapter 4.7.2.7, "Distance-to-fault measurements" , on page 228.
5.17.3.1 Controls on the Distance to Fault tab
The controls on the "Distance to Fault" tab allow you to enable and configure a stan-
dard Distance to Fault (DtF) measurement.
A standard DtF measurement is prepared in the order from top to bottom:
1. Enable DtF measurement, see "Distance to Fault" on page 762
2. Configure the distance window, see "Start Distance / Stop Distance" on page 763
3. Adjust the number of sweep points (and, if necessary, the frequency span), see
Auto Number of Points
4. Select (or define and select) a suitable cable type, see "Cable Type..."
on page 764
5. Perform a full one-port calibration at physical port 2.
You should now be able to locate the faults (peaks) by examining the trace.
You can also let the firmware generate a list of faults by enabling
Fault Limit Check
and defining a suitable Fault Limit . Use Fault List... to display (and export) the
detected faults.
Distance to Fault
Activates/deactivates Distance to Fault representation for the active trace.
Note that "Distance to Fault" can only be enabled, if the active channel is configured to
perform a linear frequency sweep .
