Activating normalization changes the softkeys that appear in the
amplitude menu: appears, and is replaced by

does not change the spectrum analyzer settings.
, like , is a trace math function that lets
NORM REF LVL NORM REF POSN
you change the position of the normalized trace within the range of the
graticule, without changing spectrum analyzer settings. See Figure
2-39. As a result, your measurement remains calibrated. However,
using these two trace math functions may mean that the top of the
screen does not represent the gain-compression limit.
