Using Display Line
Like markers, display line helps you to determine the level of the signal.
A display line is a blue straight line that runs horizontally and corresponds to a certain
level value. You can move the display line to each pixel in the display. This means that
the accuracy and exact vertical position of the display line depends on the resolution of
the vertical axis.
With a display range of 100 dB, for example, each pixel corresponds to 0.3 dB. In that
case, the accuracy of the display line is 0.3 dB. If you enter a value with a higher reso-
lution, the R&S Cable Rider ZPH rounds that value. See
Figure 4-1
.
You can also move the display line with the rotary knob. The step size for movement
with the rotary knob is one pixel.
1. Press the [LINES] key.
2. Select the "Display Line" softkey.
The R&S Cable Rider ZPH displays the display line as a blue horizontal line. It
shows the vertical position of the line in a table above the diagram area.
When you activate the display line, the R&S Cable Rider ZPH also opens an input
field to define the vertical position of the line.
3. Enter the level value you need.
The R&S Cable Rider ZPH positions the display line accordingly.
Alternatively, you can also move the display line with the rotary knob.

Using Limit Lines
Limit lines help you to identify if a signal complies with certain level characteristics.
A limit line is made up out of two or more points that are connected to a line. Each of
the points that define the shape of the limit line consists of two coordinates. One coor-
dinate defines the horizontal position (e.g. frequency), the other one the vertical posi-
