2D Spectrum Analysis
This function allows the user to employ a receiver like a spectrum scanner, and to build a
graph of all the signals received in a frequency range. This analysis is very useful when it is
necessary to choose a new frequency allocation or to choose the best frequency for a radio
link.
Enable RF-A and RF-B checkboxes to show Antenna-A and Antenna-B analysis, while Max-A
and Max-B checkboxes enables data traces relative to maximum signal level relative to a single
frequency. The test continues to cycle until it is stopped by the user. The operation, even if the
time between samples is large, assures the quality of the measure, because also intermediate
values of the signal between two samples are evaluated.
Using the functions available in the main menu it you can save the current graph data for
successive load and review, as well as print a graph or save it as bitmap image.
To perform a spectrum analysis the user must do the following tasks:
select the receiver to be used for the operation on the tree-view and start the 2D
Spectrum Scanner analysis from the popup menu or from
Tool->2D Spectrum
Analyzer
on the main menu.
Select the desired
Frequency range,
the
Step
(100/200/500 KHz , 1/2MHz) and the
Data Source
