■Simple band scope

This DSP-based simple band scope allows you to dis-
play conditions on the selected band, as well as rela-
tive strength of signals. The IC-7000 has two modes
for the spectrum indication—one is fix mode, and an-
other one is center mode.

➥ Select G-1 (Scope).

NOTE: The IC-7000’s simple band scope can mon-
itor the displayed frequency during sweeping. Both
of the receving and sweeping functions use the
same receive circuit which switch alternatively es-
pecially at high speed. Thus this switching sound
during may be irritating to listen to. If so, set the de-
sired monitoring sound, “FAST Sweep Sound,”
or change the fast sweep setting, “FAST
Sweep,” in the scope set mode (p. 73).

[MENU/GRP]

• Push and hold 

[MENU/GRP] for 1 sec. once or twice

to select the menu group G (Graphic).

• Push

[MENU/GRP] momentarily one or more times to

select the menu G-1 (Scope).

DFix mode

Displays signals within the specified frequency range.
The selected band conditions can be observed at a
glance when using this mode.

NOTE: If there is a lot of signal noise, turn the pre-
amp OFF and the attenuator ON (p. 74) to reduce
the input level and improve the readability of the
scope.

qSet a mode and frequency.

wSelect G-1 (Scope).

ePush [F-3 FIX] momentarily to select the fix

mode.

• “

O” and readout frequency indicator appear when the
fix mode is selected.

rPush [F-4 SPD] momentarily to select the sweep

speed.

• “

≈” or “≈≈” appears when Slow speed or Fast speed is
selected, respectively.

tPush [F-1 SPN] one or more times to select the

desired steps.

• ±10, 25, 50, 100 and 250 kHz are available.
• Push and hold 

[F-1 SPN] for 1 sec. to select the ±10

kHz step.

• “<” or “>” indicates when the displayed frequency is out

of range. The scope center position can be set to the
displayed frequency by pushing and holding 

FIX

] for 1 sec.

• The simple band scope operates in the peak level hold

mode. Peak levels are displayed in the background of
the current spectrum in a different color until the receive
frequency changes. This can be cleared by pushing
and holding 

[F-2 HLD] for 1 sec., or deactivated in the

scope set mode. (p. 73)

yPush [F-2 HLD] to freeze the current spectrum dis-

play.

• “

H” appears while the function is in use.

• Push and hold 

[MENU/GRP] for 1 sec. once or twice

to select the menu group G (Graphic).

• Push

[MENU/GRP] momentarily one or more times to

select the menu G-1 (Scope).
