Histogram Analyzer

 

General description

This is a tool for signal power and amplitude statistical analysis. It creates a histogram of different signal power values. This means, that in axis (Y) there are the number of values having the same power. The power value can be read from axis (X). It provides minimum, maximum, mean and standard deviation signal analysis.

 

Configuration

Pressing the right mouse button over the histogram display will open the following pop-up menu.

 

 

Parameters

 

Stop/Start

The histogram calculation and display updating can be started or stopped with this switch.

 

Auto scale

If this is switched on, the display is automatically scaled.

Zoom out

This returns the zoom to the original value.

 

Grid

This activates the grid in the histogram display.

 

Average

This activates the histogram value averaging in the display.

 

Maximum

This activates the "max and hold" function in the histogram display.

Update interval

This defines an interval for the display updates.

 

Properties

This opens the configuration dialog shown below:

 

 

 

 

The properties parameters are:

 

MAXIMUM AMPLITUDE

This is the scale for the ‘X’ axis in histogram display.

 

BIN COUNT

This is the number of different power levels in the ‘Y’ axis.

 

AVERAGE IIR FACTOR

This is the averaging filter parameter. If this number is small, the filter will be narrow. This parameter is active only when ‘Averaging’ is activated

 

ABSOLUTE VALUES

The histogram shows only the absolute values (these values are always positive)

 

NORMALIZE

The histogram maximum value will be normalized to 100.

 

MIN

If this is selected, the Minimum value will be shown on the display

 

MAX

If this is selected, the Maximum value will be shown on the display

 

MEAN

If this is selected, the Mean value will be shown on the display

 

STD DEV

If this is selected, the Standard Deviation value will be shown on the display

 

COUNT

If this is selected, the number of samples used in the analysis will be shown on the display

DRAW MODE

This defines the mode in which the results will be plotted (line/bar).
