Frequency Menu
 Center Freq: Center frequency in MHZ
 Freq Span: Frequency span (or range) to display on screen in MHZ
 Start Freq: Lower frequency range to display on screen in MHZ
 Stop Freq: Higher frequency range to display on screen in MHZ
 Module: Active selected RF module. When an expansion module is installed, click [Enter] key to
enable the module you need.
The selected frequency band to display can be specified in two different but complementary ways:
 Center/Span: This is the traditional Spectrum Analyzer format all engineers are used to. You
basically select the Center frequency at which the band will be displayed, and then a Frequency Span.
 Start/Stop: This alternative mode is very useful to select frequency range between two frequencies
of interest, with no need to manually calculate the Center or the Span.
The valid values for Frequency and Span are defined based on RF Explorer model and operational mode.
As you edit Center/Span or Start/Stop, the other values are updated accordingly, so feel free to use the
method you prefer. In general, you will use Center/Span more frequently when you know the frequency you
want to look at, and probably Start/Stop when you just want to look at a larger span to see what is
happening in a specific range.
To navigate through the menu, just use [Up] and [Down] keys to go to the option you want, then click on
[Enter] to edit that option, [Left] or [Right] to go to the digit you want to change, and [Enter] to confirm or
[Return] to cancel.
