Graphical user interface for noise estimation using SSA3021X

Simple graphical frontend for an SSA3021X spectrum analyzer to perform simple noise measurements. It assumes one measures a single peak against background.

The utility requires the spectrum analyzer to:

• Be set to linear scale (this will be fixed in later versions)
• The center frequency should be set to the desired signal frequency. The program picks the largest peak as signal though.
• The quarter of samples on the left and to the right of the span is used as basis to calculate the noise floor of the signal.

Installation

This package can be installed simply via pip

pip install ssa3021xnoisegui-tspspi

Usage

ssa3021xnoisegui

Configuration file

One can pre-set some configuration variables in a configuration file at ~/.config/ssa3021xrealtimenoisegui.cfg. All variables are optional:

{
	"ssa" : {
		"ip" : "10.4.1.18"
	},
    "sampling" : {
        "window" : 10,
        "interval" : 0.5,
        "storedsamples" : 1000
    }
}
