5.2.3 Configuring the Vertical Axis
The amplitude menu contains all settings related to the level display.
5.2.3.1 Adjusting the Scale of the Diagram
The R&S FSH provides several options to improve the vertical scaling of the
measurement diagram.
The unit of the level axis is dB.
Setting the reference value
The reference value defines the amplitude of the reference line. The unit of the
reference is dB.
The R&S FSH indicates the position of the reference value with a yellow triangle at the
vertical axis (
).
When you change the reference value, the R&S FSH adjusts the labels of the vertical
axis. Changing the reference value changes the vertical position of the trace. It does
not change the position of the reference line.
M
Press the AMPT key.
M
Press the "Ref" softkey.
M
Enter the reference value you want or move the reference with the rotary knob.
The R&S FSH sets up the display accordingly.
Defining the display range
The display range defines the scale of the vertical axis and therefore the amplitude
between two horizontal grid lines.
The unit depends on the measurement format.
When you change the display range, you can increase or decrease the amplitude the
R&S FSH displays and, e.g. include signal parts that are outside the displayed screen
area. The position of the reference value and the trace do not change.
M
Press the AMPT key.
M
Press the "Range " softkey.
