A-B.3 Analyzer Mode To enter in the ANALYZER Mode it’s enough to depress the Analyzer soft key
on the main screen.
In this mode the receiver works as a powerful Spectrum Analyzer and the
display shows the "spectrum analysis" in the frequency domain of a signal
tuned at a given frequency.
The analysis is done at the selected span frequency.
Using the marker facility the User can accomplish a very accurate
measurement of the signals either in frequency as well as in level.
A-B.3.1 RBW
Selection The Spectrum mode function is divided into five sub windows:
• Frequency
•
Resolution Bandwidth
•
Level
• Marker
•
Wide Mode
The fifth button is used to change the spectrum view to
wide screen mode,
as shown in the picture 5-1, and with the Esc button the original view can be
restored.
Always use Esc button to return to the previous view/condition

measuring filter.
The three larger filters are selectable from the first RBW screen, and pressing

• 100 Hz MIL at -6dB
