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. It may also be used with
receivers which have an IF ‘close’ to 10.7 MHz (in the range 5.7 to 15.6 MHz
with reduced bandwidth) such as the Kenwood TS870S where the SDU5500 makes an
excellent companion band scope so that adjacent channel activity may be
constantly monitored, (on VHF this is particularly popular with frequency
management organisations). 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!
- 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.
- Ready-to-go
Supplied in the UK with 9-9pin radio connector for
the AR5000, d.c. lead and
operating manual (a suitable 12V power supply will be required along with BNC
patch lead).
- 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.
