IF 신호를 信機型
수신기의 신호를
디지털 처리하여
다기능 모니터 스코프를
실현하는 스펙트럼
디스플레이 유니트이다.
동작 방법은 대형
LCD 화면상에서 표시되는

다양한 기능을 쉽게
조작할 수 있도록
설계되어 있습니다.
광대역
수신기와 연결
이기기는
광대역 수신기 AR-500에
연결하여 사용하는
것을 전제로 개발되었습니다.
AR-5000과 연결하여
사용할 때에는 AR-5000
수신 주파수 (중심주파수:
CF) 또는 수신 모드를
SDU-5500에서 설정할
수 있습니다. SDU-5500을
AR-5000과 연결할
때 SDU-5500 화면상에
나타나는 신호를
바로 AR-5000에서도
수신할 수 있는 획기적인
수신 시스템입니다.
또, 아이콤의 IC-R8500
기기에도 사용이
가능합니다.
새로운
觀測 모드
이기기에는
일정한 간격으로
할당되어 있는 전파를
관측할 때 적합합니다.(스텝래소튜션
모드). 채널 스코프
모드는 아마추어
무선의 주파수대에
할당되어 있는 전파를
관측하는데 유효하고
편리합니다.
The
"all new"
SDU5500 Spectrum
Display Unit
For
years AOR has been
marketing the worlds'
first colour spectrum
display unit SDU5000 for
the professionals
and top-end of amateur
listeners. The SDU5500
is a worthy successor
to the SDU5000 (which
offered practical
and cost effective
monitoring), using
a large high resolution
LCD display backed
by the latest microprocessor
technology. Coupled
to the AR5000 receiver,
it provides a spectrum
display of 10 MHz
bandwidth anywhere
between 10 kHz and
2600 MHz.
The
SDU5500 has a
(larger) high resolution
monochrome (white/blue)
LCD with
improved status
read-out on the
top-half of the
display with a spin
wheel tuner controlling
the marker position,
similar to a dedicated
high-priced spectrum
analyser. On screen
programming is provided
via on-screen menus
with six keys controlling
selection in addition
to the numeric keypad
for frequency entry.
Briefly... the
SDU5500 adds a variety
of features to extend
your receiver's
capabilities, such
as visually identifying
new active frequencies
and taking measurements.
The SDU5500 may
be used with a number
of receivers (which
have a 10.7 MHz
I.F. output) and
provides a bandwidth
up to ± 5 MHz in
1 kHz increments
with a resolution
of 5 kHz or 30 kHz.
When using selected
AOR and ICOM receivers,
the frequency, mode
(& attenuator
with some sets)
may be controlled
from the SDU5500.
The SDU5500 may
also be connected
to a PC where all
controls are accessible
and display data
can be downloaded
for record and later
analysis, you may
measure the frequency
and signal strength
of historical events!
Key
Points
- Menu
driven operation
All facilities
are within easy
access through
each dedicated
function key
and on-screen
menu.
- Full
inter-connection
with the AR5000
The AR5000 can
be operated
from the SDU5500
enabling selection
of centre frequency,
receive mode,
etc. Any frequency
spotted and
monitored by
the SDU5500
can be received
by the AR5000
straight away.
- Direct
reading of the
receiving frequency
and input level
By placing the
cursor on any
spot frequency
you can read
its frequency
and input level
on screen. When
connected with
the AR5000 the
SDU5500 virtually
works as a spectrum
analyser over
10 kHz to 2600
MHz range as
the centre frequency
always becomes
the receive
frequency.
- Wide
spectrum coverage
The SDU5500
covers a maximum
of +/-5 MHz
spread against
the input frequency.
- Dual
frequency resolution
Selectable,
either 5kHz
or 30kHz resolution.
- Wide
input range
-10dBm
to -90dBm by
using two selectable
gain settings.
- Highly
accurate frequency
management
Through
the DDS controlled
local oscillator
circuit.
- Wide
variety of displays
Graphical display
and statistical
analysis.
- Remote
control via
PC
All keyboard
operations of
the SDU5500
can be mimicked
by PC.
- Compatibility
with non-AOR
radios
Any radios
which are equipped
with a 10.7
MHz IF output
can work with
SDU5500. Sweep
direction is
selectable depending
on the heterodyne
configuration
of the radio.
Sweep span may
be narrower
subject to the
IF characteristics
of the radio.
