Chapter 13.10.10, "Display Lines"
Like markers, display lines help you to determine the level of the signal.
A display line is a 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 resolution, the R&S
FPC1000 rounds that value.
