4 Menu System
4.1 Control via the Menu System
The default menu system for the instrument consists of three rows of five keys. The upper row
represents the top level of the menu system and defines five menu groups as follows:
Freq/Span controls the frequency range of the spectrum analyzer, as well as Zero Span mode.
Sweep/BW controls the sweep and sets the RBW.
Level/Limits controls the input attenuator, plus the scaling of the amplitude display. Limits is
only available with option U02 fitted.
Traces/Markers controls the traces that appear on the screen (including store/recall) and the
markers that are used for measurement.
Setup/Functions controls specific measurement functions and instrument setup store and
recall. Automatic Measurements and Logging are also controlled with option U02 fitted.
Each group has up to five sub-groups which appear on the middle row of keys. The currently
selected group and sub-group are shown by the relevant keys being dark blue.
The bottom row of keys represent the functions that can be performed for each of the many
sub-groups. These keys may perform an immediate action, or bring up a pop-up menu, or
create a dialogue box for user entry. Specific functions such as frequency entry and filing
system operations replace the normal menu keys with a new set of keys relevant to the current
function.
4.2 Hard Keys
Run/Stop (Manual) controls the sweep. It duplicates the function of the touch screen key
directly below the graticule.
Exit (Cancel) terminates any pop-up menu or dialogue box.
Status (Help) brings up complete listings of the instrument status, and gives access to the
System Utilities and on-screen Help.
View (Live > View) copies an instance of the Live trace to the View trace. This duplicates the
action of the soft key Traces/Markers > Traces/Stores > View.
Presets (Auto Set) activates the Presets menu: Standard Preset, User Preset and Auto Set.
Navigator Keys the five hard keys that make up the Navigator have two alternative modes of
operation which are selected by the small illuminated keys on either side. The modes are:
Control Markers (default), and Navigate Screen (see section 2.9.1).
Whenever the navigator mode is changed, an information box appears explaining the current
action of the navigator keys. This can be turned off if preferred from
Status > Status/System > Alerts > Navig. Prompt.
4.3 Frequency/Span
4.3.1 Frequency/Span > Centre
Pressing Centre changes the top line annotation to Centre/Span if it was previously
Start/Stop. The five keys on the bottom row enable the centre frequency to be
changed:
Set Centre brings up a numeric keyboard from which the desired frequency can be
entered in MHz to a resolution of 0.0001 (100Hz). Pressing Set by ‘Tab/Jog’ from
this screen provides an alternative frequency editing mode. Pressing ‘Set by K/B’
from this screen returns to the numeric keyboard setting screen. Pressing ‘Exit’ returns to the
main Centre menu. The last used mode (K/B or Tab/Jog) is retained.
