Setting up the level parameters
After specifying the unit for your reflection measurement you can
adjust the level parameters. Depending on the unit you specified via
the Units menu the display of the Level menu changes to enable you
to set the level parameters for the individual units as follows:
Setting the reference
level for return loss
1 In the main menu, push the Ref. softkey or select Level followed by
Ref. Alternatively, push the REF function key.
The Reference Level input field opens.
2 Enter the new reference level either using the numeric keys,
closing the input field with the appropriate enter key, or with the
U
P/DOWN arrow keys.
The new reference level appears at the top of the vertical axis. The
reference is based on the actual set output power.
Changing the vertical
scale for return loss
The scale for the vertical axis (power) can be changed in the range
from 1 to 20 dB per division (vertical line in the displayed grid) in 1-3-
5 steps as follows:
