FUNCTIONS FOR RECEIVE
■
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).

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.
