Manual operation:
CALCulate<Chn>:TRANsform:DTFault:POINts
If the active trace of channel <Chn> is a Distance to Fault (DtF) trace, this command
starts the "Auto Number of Points" calculation (see
on page 729).
An execution error is raised, if the calculated number of points is higher than the maxi-
mum number of sweep points the firmware allows (100001). To avoid this, reduce the
frequency span Δf (see
stop frequency d
2.6 · d
where v denotes the velocity factor of the measured cable (see
TRANsform:DTFault:SELect).
