dB
Default unit: dB
Example:
*RST; :CALCulate1:TRANsform:DTFault:STATe ON
makes the active trace of channel 1 a DtF trace.
CALCulate1:TRANsform:DTFault:PEAK:THReshold -30
sets the DtF limit to -30 dB.

Manual operation:
See
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
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

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.
