Note:
The frequency domain window is used to filter the trace before transforming it to
the time domain. An independent "Time Gate" can be used after the transformation to
eliminate unwanted responses (see
Chapter 5.5.6, "Time Gate tab"
The analyzer always uses a "No Profiling (Rectangle)" window to calculate the time-
gated frequency domain trace, see
"Time-gated frequency domain trace"
Remote command:
CALCulate<Chn>:TRANsform:TIME:WINDow
Side Lobe Level
Defines the side lobe suppression for an "Arbitrary Sidelobes (Dolph-Chebychev)" win-
dow. The entered value is the ratio of the power of the central lobe to the power of the
first side lobe in dB.
Remote command:
CALCulate<Chn>:TRANsform:TIME:DCHebyshev
Resolution Enh.
Broadens the frequency range that the analyzer considers for the time domain trans-
form by a linear factor. A factor of 1 means that the original sweep range and the mea-
sured sweep points are used; no additional assumptions are made. With higher resolu-
tion enhancement factors, the measurement data is extrapolated using a linear predic-
tion method. As a result, the resolution in time domain can be improved.
The ideal resolution enhancement factor depends on the properties of the DUT. For
distance to fault measurements on cables, set it to 1.
Remote command:
CALCulate<Chn>:TRANsform:TIME:RESolution:EFACtor
TD-VSWR
Enables time domain site VSWR measurements (see
Remote command:
Gate Span
relies on a time gate that is centered at the anten-
na's direct response (plus ring-down time), separating the direct response from the
indirect responses (reflections).
"Gate Span" is equivalent to the "Span" value on the
