7 BANDSCOPE BANDSCOPE The Bandscope displays the signal strength along the vertical axis and the frequency along the horizontal axis, allowing you to observe the status of the received frequency. There are two modes available: Center mode, which places the receive frequency at the center of the horizontal axis, and Fixed mode, where the lower limit frequency and upper limit frequency for the displayed band are fixed.

7 BANDSCOPE
Index
Contents
BANDSCOPE
The Bandscope displays the signal strength along the
vertical axis and the frequency along the horizontal
axis, allowing you to observe the status of the received
frequency.
There are two modes available: Center mode, which
places the receive frequency at the center of the horizontal
axis, and Fixed mode, where the lower limit frequency and
upper limit frequency for the displayed band are fixed.

DISPLAYING THE BANDSCOPE
1
Press
[SCP]
to display the bandscope on the main
display.
Each time you press
[SCP]
, the screen cycles through
Bandscope > Bandscope and Waterfall > No Bandscope
Display > Bandscope.
2
Press
[ESC]
to exit.
WATERFALL
Displaying the waterfall below the bandscope allows
you to observe the transition of the signal strength in
addition to the state of the received signal and its adjacent
frequencies.
In the waterfall display, the vertical axis represents
elapsed of time and the horizontal axis represents the
frequency.
The signal strength is distinguished by its color on the
display; white (strong), red to yellow (medium) and green
to blue (weak).
The spectrum of the signal strength for the range
equivalent to the four times of the red marker appears
vertically. The span until the next red marker appears (in
other words, waterfall fall speed) can be changed.
While the Waterfall is being displayed, the bandscope
height is reduced to one third compared to when only the
bandscope is displayed.
Note:
In Center mode, the waterfall display pauses if the receive
frequency is changed.
In Fixed mode, with the observation of the target signal (vertical
trace) displayed on the Waterfall, shift the marker position to tune
the signal.
PAUSING THE WATERFALL ±CENTER MODE²
You can pause the waterfall display while the frequency of
the target band on the scope is altered in the center mode.
1
Select Group No. 8, “Bandscope”, from the
Menu
screen.
2
Access Menu 33, “Waterfall Pause when Tuning
(Center Mode)”.
