Thanks to the AUTO RANGE mode it is possible to adapt the upper and lower signal levels of the screen to the
automatic measurement levels. Thanks to the FULL / EMPTY function: you can see the levels in the spectrum screen
as full or empty (fig. 39). By pressing the EDIT button it is possible to modify the IF Frequency, Span, Reference,
Gamma, Power and Mode values (fig. 40). With the MODE option it is possible to modify the spectrum speed
(NORMAL or FAST): when it is in NORMAL mode the spectrum will move at the optimal speed. When the FAST mode
is selected the spectrum will move faster (in this case the image may not be displayed in detail).
