displays for graphic systems that allow multiscan recording (Sweep Graph 1 to 4) the
current value, the so-called scan index. Number 0 means the most recent scan. The
lower the negative number, the older the scan.
Scans identified as Min and Max are available to all graphic systems, provided they
are activated.
If Cursor is switched on in the graph, an O or X identifies the intersection of the cursor
with the current trace or trace pair. If the scan index changes, this marking jumps to the
next scan.
If the measured value list is enabled,
the lists are reconfigured after every change in the scan index, because only one scan
is displayed in the measured value list.
5.46.7 Interpolation on the Common x-axis
So that any number of traces can be used as reference or displayed simultaneously for
comparison and measured with the cursors, such traces should actually all have the
same X values. The R&S
UPP, however, can use any X divisions, by interpolating the
measured value sequences, reference traces and limit curves onto the current x-axis.
The Equalization Lists are also interpolated on the x-axis of the generator sweep and
the waiting time curves for sweep stepping.
Reference traces, limit curves and waiting time curves therefore need consist of only a
few interpolation points. The interpolation takes into account whether the x and y-axes
are divided on a linear or logarithmic basis, because segments of ellipses are generally
produced from straight lines in the other display.
5.47 Result List
All measured values from all graphic subsystems can also be displayed in lists instead
or in combination with the graphical windows.
