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
on page 883) and/or the
stop frequency d
stop
(see
CALCulate<Chn>:TRANsform:DTFault:STOP
2.6 · d
stop
· Δf / (v · c
0
) ≤ 100001
,
where
v
denotes the velocity factor of the measured cable (see
).
Suffix:
<Chn>
.
Channel number used to identify the active trace
Example:
*RST; :CALCulate1:TRANsform:DTFault:STATe ON
makes the active trace of channel 1 a DtF trace.
SENSe1:SWEep:POINts?
returns the default number of sweep points (201).
:CALCulate1:TRANsform:DTFault:STARt 0; STOP 100
widens the DtF distance window to 100m.
CALCulate1:TRANsform:DTFault:POINts
starts the "Auto Number of Points calculation". Now
SENSe1:SWEep:POINts?
returns an increased number of sweep points.
