Key Function Tables
This chapter describes the functions that are available from the front
panel of 8560 E-Series and EC-Series spectrum analyzers. The tables at
the start of the chapter list the front-panel keys and softkeys by their
functional groups with the location of the key and a very brief
description. The functional groups are:
• Fundamental Functions ( page 184)
• Instrument State Functions ( page 186)
• Marker Functions ( page 197)
• Control Functions ( page 199)
Following the tables of key locations, each key and softkey is listed
alphabetically along with a detailed description of its operation. The
front-panel key under which the softkey can be found is indicated at the
end of this description.

Access Key Description
— Activates the reference level function and accesses a
menu of amplitude related functions.
Accesses a menu of amplitude units.
AMPLITUDE
Adjusts the spectrum analyzer input attenuator that is
AMPLITUDE
either coupled to the reference level (AUTO) or adjusted
manually (MAN).
Activates the center frequency function and sets the
FREQUENCY
spectrum analyzer to center-frequency span mode.
Sets the center frequency of the spectrum analyzer to the
FREQUENCY
currently-displayed center frequency divided by two.
This softkey appears in firmware revisions >941028.
Sets the center frequency of the spectrum analyzer to the
FREQUENCY
currently-displayed center frequency times two. This
softkey appears in firmware revisions >941028.
Adjusts the center frequency step size so that when a
FREQUENCY
step key is pressed, the center frequency shifts by the
selected step size.
Selects ac or dc coupling to the input; ac coupling
AMPLITUDE
protects the input of the analyzer from damaging dc
signals. When dc coupling is selected, a C appears on the
left edge of the display. Not available with an Agilent
8563E/EC,, Agilent 8564E/EC or Agilent 8565E/EC.
Selects absolute decibels relative to 1 mW as the
AMPLITUDE
amplitude units.
