Configuring the Vertical Axis
The [SCALE] or [SCALE/AMPT] key contains menu on settings related to the level dis-
play.
7.2.3.1
Setting the Reference Value
The reference value defines the amplitude of the reference line. The R&S Cable Rider
ZPH indicates the position of the reference value with a white triangle at the vertical
axis.
When you change the reference value, the R&S Cable Rider ZPH adjusts the labels of
the vertical axis. Changing the reference value results a change in the vertical position
of the trace. It does not change the position of the reference line.
