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.
The selected frequency band to display can be specified in two different but complementary ways:
•
Center/Span
: This is the traditional Spectrum Analyzer format many engineers are used to. 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.
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 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.
