11.5.1 Display Lines
11.5.1.1 Basics on Display Lines
Display lines help you analyze a trace – as do markers. The function of a display line is
comparable to that of a ruler that can be shifted on the trace in order to mark absolute
values. They are used exclusively to visually mark relevant frequencies or points in
time (zero span), as well as constant level values. It is not possible to check automati-
cally whether the points are below or above the marked level values - use limit lines for
that task (see Chapter 11.5.2.1, "Basics on Limit Lines", on page 241).
Two different types of display lines are provided:
●
Two horizontal lines: "Horizontal Line 1" and "Horizontal Line 2".
These lines are continuous horizontal lines across the entire width of a diagram
and can be shifted up and down.
●
Two vertical lines: "Vertical Line 1" and "Vertical Line 2"
These lines are continuous vertical lines across the entire height of the diagram
and can be shifted left and right.
Lables
Each line is identified by one of the following abbreviations in the diagrams:
●
H1: "Horizontal Line 1"
●
H2: "Horizontal Line 2"
●
V1: "Vertical Line 1"
●
V2: "Vertical Line 2"
●
Each label also shows the absolute position of the corresponding line, for example
"H1 70.000 dBµV".
If you turn on both horizontal lines or both vertical lines, the label of the first line
also shows the distance to the second line, for example "H1 70.000 dBµV, Δ 8.250
dB".
