10.11 - Analyzer Mode Operating Instructions
10.11.1 Introduction
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" (span max 3 GHz) 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.
Entering
Analyzer Mode from the main menu, the display will look like the
following:
Fig. 10-15 Spectrum
The SPAN per division is automatically managed by the equipment.
On the screen of the Analyzer Mode all the relevant information are reported.
From the upper left corner, the User can see if the Preselector is ON or OFF;
if the Preamplifier is ON or OFF; which detector is in use and the relevant
hold time; if the input attenuation is Automatic or Manual and the set
attenuation and if the Minimum attenuation is 10 dB or 0dB.
Just above the graph, from left to right, there is the Reference level, the
Resolution bandwidth and the span value.
Below the graph the start, center and stop frequency.
The bottom left corner is dedicated to the marker indication, with actual
frequency and level of the marker.
