Configure
All options selected within this menu are pending settings and will not take effect until the unit is
reconfigured. The settings are only saved when the unit is reconfigured and will be lost if the user
exits out of the configure menu or the unit is power cycled.
The options under this Menu will vary and depend upon the chosen coding scheme; this is stated
in the list below. It is recommended that the entry be done from top to bottom then only
applicable menus will be displayed. The Configure sub-menu may be viewed by selecting the
Configure option from the Select Board menu. The options available are detailed in Table 3.5.

The values available for roll-off are: 0.15, 0.20, 0.25, 0.30 and 0.35
Search Range:
The Search range can be set from 0 to 20 MHz. This should be set depending
upon the amount of uncertainty of the carrier.

The Step size of the search can be set from 0 to 500 KHz.
Spectral Analysis:
The setting of this value will be ON, OFF or Auto. If enabled then a FFT will be
performed to aid acquisition.

The coding scheme is chosen from a list which is dependant upon the feature
keys that are installed.
3.3.2.2.1
Profiles
The user can store and recall configurations with clear user-definable names. The stored file is
shared by all user interfaces so the GUI could be used to clone a configuration to several units
and the front panel could retrieve this setting. The Profiles sub-menu allows the user to access
these configurations.
Note
The front panel is slightly more restrictive than the GUI due to the limited display and key entry system
but is still easy to use.
To load, delete or create profiles:
1.
Select the Profiles option from the Configure sub-menu. The options displayed are detailed
in Table 3.6.
