Panafall
This display is a combination of the Panadapter and the Waterfall displays described above.
Panascope
This display is a combination of the Panadapter and the Scope displays described above.
Off
In this setting the display is turned off. It is mainly used for debugging purposes, but can also be used
with slower systems to decrease the CPU load to more reasonable levels.
Cursor and Peak Position
There are two sets of data side by side under the display that are used to communicate cursor (left)
and peak signal (right) information to the user. For each the data shown equals Offset from VFO, Signal
Level and Frequency. For example, in Figure 51 below, the peak signal is offset -8639.4 Hz from the
VFO frequency (14.187 MHz). The peak signal level is –81.6 dBm, and the peak signal is at 14.178361
MHz. Note that these values are fairly low resolution due to the discrete nature of the pixel display.
Figure 51: Cursor and Peak Position Information
In the frequency domain displays (Spectrum, Panadapter, Histogram, Waterfall), right clicking
the mouse cycles through yellow crosshairs, red crosshairs (only if
SPLT
or
MultiRX
is
enabled), or no crosshairs. The crosshairs span the width and height of the display (yellow
cross hairs are shown in Figure 51 above).
Together with the
AVG
control they allow easy measurement of signals on the display. For
example, in Figure 51 the cursor position is offset -10230.3 Hz from the VFO frequency and is
at 14.176770 MHz. Its “level” is at -80.6 dBm.
Another feature of the crosshairs is ClickTuning. Clicking the left mouse button with the yellow
crosshairs visible tunes VFO A to the frequency indicated by the cursor position data (or if Snap
ClickTune is on (see page 67), to the nearest multiple of the Tune Step). The red crosshairs
