[ F7 ( LBWS )] Key
Press this key to activate the "Limited Band Width
Sweep" (LBWS) function, which permits high-speed
sweeping of a band segment.
As the bandwidth is set narrower, the sweep speed
becomes faster, allowing the scope to capture signals
with quicker resolution. The bandwidth can be set to
50 %, 30 %, or 10 % of the full span. The sweep speed
becomes faster by the following amounts:
50 %: about 2 times faster
30 %: about 3 times faster
10 %: about 10 times faster
NORMAL LBWS-1 ( 50% )
LBWS-2 ( 30% ) LBWS-3 ( 10% ) NORMAL ......
Advice: When you enter the LBWS mode, the func-
tion keys below the Display change.
It is possible to move the sweep position by pressing
the [ F5 ( )] and [ F6 ( )] key.
If you want to return to normal operation, press the
[ F7 ( LBWS )] key as needed.
Please note that LBWS can not be used in the FIX
mode. Please use LBWS only in the CTR mode.

key's function between the "Page Select Key" and the

[ MENU ] button momentarily. The radio will go back
to the previous condition/situation.
There are many setup items in the Menu mode, and
they are grouped for easy recognition; the group name
is displayed at the top left corner of the list screen. It
is usually more convenient if you initially select the
group by rotating the Main Tuning Dial knob, and then
select the item you want.
