When you are displaying only +/- 20kHz in the Panadapter, it is no problem to display 0Hz in the center.
But suppose we want to display +/-40kHz. We now run into a problem on the right because we run out of
spectrum at +37kHz. The Panadapter does not display spectrum where there is no possibility of signals and
instead shifts the 0Hz mark to the right.
Display Type Controls
The main display is able to visualize received (and transmitted) signals in various ways (display types),
which can be selected from the list box. These various display types are detailed below with a snapshot of
each type. The sampling rate (Frames Per Second, FPS) of the main display can be modified on the Setup
Form-Display Tab.
AVG (Average): click to view time-averaged signals. This will smooth fast-changing signals and is
a good way to separate real from stochastic (noise) signals. The averaging time can be set on the
Setup Form-Display Tab. Average must be enabled for the 0 Beat function to be enabled.
Peak: click to hold the peak value for each frequency in the display.
Display Type Descriptions
Note 1: All displays show a 7.0401MHz, -73dBm signal from an Elecraft XG-1
signal generator.
Note 2: The actual software display is crisper than the compressed images shown
below.
There are four frequency domain display types (Spectrum, Panadapter, Histogram, and Waterfall) and three
time domain display types (Scope, Phase and Phase2). The colors of everything on the display (text, data
line, background, etc) are completely customizable using the Setup Form-Appearance Tab.
