Adjust the frequency sweep to the length of the transmission line and the expected dis-
tance to fault:
●
The maximum distance that can be measured is proportional to the number of
sweep points. The larger the number of sweep points, the longer the maximum dis-
tance between the calibrated reference plane and the fault to be located.
●
The maximum distance that can be measured is inversely proportional to the fre-
quency span. The smaller the frequency span, the longer the maximum distance
between the calibrated reference plane and the fault to be located.
However, a smaller frequency span comes at the cost of a coarser distance resolu-
tion.
The R&S
ZNB/ZNBT can automatically determine a suitable number of sweep points
for a given maximum distance to fault ("Auto Number of Points"). Moreover it is possi-
ble to define which of the peaks are considered as being due to a fault, and to draw up
and export a list of the detected faults.
