SET-UP & BASIC OPERATION

Preset Spans
The range of frequencies swept by the tuner, or tuner span, can be adjusted during operation by
changing one or more of the spectral parameters (see page 32). Custom spans may be configured,
named, and stored in memory for easy recall later. Several default tuner spans are available on the
OSCOR from the factory:
o Full: The tuner will sweep the entire frequency range available on the OSCOR (100 kHz
to 24 GHz for 24 GHz models and 100 kHz to 8 GHz for 8 GHz models)
o 3 GHz: The tuner will sweep from 100 kHz to 3 GHz
o 8 GHz: The tuner will sweep from 100 kHz to 8 GHz (available on 24 GHz models)
o FM: The tuner will sweep the FM radio broadcast band, from just below 87.5 MHz to
108 MHz
To change the tuner span:
1. From the Main Menu select Setup or press F1.
2. Select the Spans icon from the Setup Sub-Menu.
3. In the Select Span dialog box that appears, a list of available user spans will be displayed.
4. Highlight the desired user span and press Select. The dialog box will close and the new span will
be applied.
Note: If Detail Zoom is on (see page 45), the selected span will apply to the Detail View and not to the
tuner. If the selected span is outside the range of the current tuner span, then the new span will not be
applied to the Detail View.
