Parameters:
<DtfPeakState>
OFF|ON (0|1)
Example:
*RST; :CALCulate1:TRANsform:DTFault:STATe ON
makes the active trace of channel 1 a DtF trace.
CALCulate1:TRANsform:DTFault:PEAK:STATe ON
enables DtF limit checking.
Options:
R&S
ZNB/ZNBT-K3
Manual operation:
See
CALCulate<Chn>:TRANsform:DTFault:PEAK:THReshold
<PeakThreshold>
If the active trace of channel <Chn> is a Distance to Fault (DtF) trace, this command
allows to set the fault limit for DtF limit checking.
Use
CALCulate<Chn>:TRANsform:DTFault:PEAK:STATe
to enable DtF limit
checking.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<PeakThreshold>
Fault limit
*RST:
-20
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
