3.2.2 ANALYZER
MODE
The purpose of this operating mode is to make an easy and fast debugging
tool available to the User.
To enter the
ANALYZER Mode it’s enough to tap the Analyzer software 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.
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.
On the screen of the Analyzer Mode all the relevant information are reported.
So that the User can see which detector is in use and the relevant hold time; if
the input attenuation is Automatic or Manual and the set attenuation and the
Minimum attenuation.
Near the graph there is the Reference level, the Resolution bandwidth and the
span value.
Below the graph the start, center and stop frequency.
A proper box is dedicated to the marker indication, with actual frequency and
level of the marker.
3.2.2.1 Frequency The Frequency menu features five function buttons:
Touch
Center to enter the center (mean) frequency for the analysis.
Touch Start to enter the start (minimum) frequency for the analysis.
Touch Stop to enter the stop (maximum) frequency for the analysis.
Touch Span to enter the frequency span (width) for the analysis
Using these buttons, the User can set any frequency interval for the
measurement; to enter the frequency values, tap the corresponding function
keys.
When one of these function keys is touched, a software keyboard appears,
allowing the User to enter numerically the desired frequency and unit (Hz, kHz,
MHz or GHz) as well as the decimal dot and the Back Space.
