X-Value of the Sweep Point
As described in
"Mapping Samples to sweep Points with the Trace Detector"
on page 390, the number of samples taken during a sweep can be much larger than
the number of sweep points that are displayed in the measurement trace.
To determine the x-value of the sweep point, two different methods are available:
●
Start/stop
●
Bin-centered
Start/stop
This is the default (legacy) method for trace values in the frequency domain. The x-
value of the first sweep point corresponds to the starting point of the full measurement
span. The x-value of the last sweep point corresponds to the end point of the full mea-
surement span. All other sweep points are divided evenly between the first and last
points. The distance between two sweep points is span/(<no_sweep_points> -1).
Bin-centered
This is the default method for all marker values. The full measurement span is divided
by the number of sweep points. The result is the span that is evaluated for an individ-
ual sweep point, also referred to as a
bin
. The x-value of the sweep point is then
defined as the x-value at the center of the bin (bin/2).
