SDU5500 -

Spectrum Display Unit

spectrum display unit for use with a companion receiver

The SDU5500 is an ‘all new’ Spectrum

Display Unit and a worthy successor to

the SDU5000 (which offered practical

and cost effective monitoring). It has

never been so easy to locate those brief

elusive transmissions, coupled to the

AR5000 receiver, the SDU5500

provides a spectrum display of 10 MHz

bandwidth anywhere between 10 kHz

and 2600 MHz. Already pressed into

commercial usage by government

departments, the professionalism of

the unit has truly been grasped.

The SDU5500 has a high resolution

monochrome 4.7inch (white/blue) LCD with improved status read-out on the top-half of the

display, a spin wheel tuner controlling the marker position and on-screen programming similar

to a dedicated high-priced spectrum analyser. There are six program keys in addition to the

ten-key pad. It gets even better... compared to its predecessor, several new facilities have

been provided:

u Step resolution mode, plots the wanted channel steps and ignores the gaps for more efficient analysis.

u Channel step mode, plots the wanted channels for close in use on channelised bands.

u Spectrum mode is of course available with peak, max, average etc.

u Support for AOR AR5000/5000+3, AR3000A, ICOM R7100, R8500, R9000 and ‘Other’ companion radio.

Frequency accuracy is typically around ± 600Hz with a usable dynamic range of 50dB and

acceptable input level between -10dB to -90dB with selectable gain control. The SDU5500

truly adds a variety of features to extend your receiver's capabilities, such as visually

identifying new active frequencies and taking measurements. Multiple process functions allow

average level, peak detection, maximum hold and much more. The SDU5500 may be

connected directly to a computer for hands-off control. Built-in support is provided for a

number of AOR and ICOM receivers which have a 10.7 MHz i.f. output (AOR AR5000/+3,

AR3000A and ICOM R7100, R8500 & R9000). A spectrum bandwidth up to ± 5 MHz in 1 kHz

increments is provided with a resolution of 5 kHz or 30 kHz. VDU5500: New optional module

for the SDU5500, adds vector graphical analysis of transmissions (including digital GSM etc)

with data dump of node points (workshop fitting required).

Supported companion radio AR5000/AR5000+3, AR3000A, IC-R7100,

IC-R8500, IC-R9000 and other radios with

10.7 MHz IF output (non active)

Requirements

AR5000/+3 receiver : Everything is supplied for straight forward connection of the radio

control and i.f. interconnections.

AR3000A receiver : A small modification is required to the AR3000A in order to provide a

10.7 MHz i.f. output and AGC control. A 9-25 way RS232 type lead or 9-25 way adapter

will be required for connection to the radio, a BNC-BNC patch lead is provided for i.f.

connection.

ICOM R8500 : This unit provides direct radio (RS232) connection so that the lead provided

(with the SDU5500) connects straight from the SDU5500 to the rear panel RS232 socket of

the R8500. The i.f. patch lead will require the changing of one BNC plug as the ICOM i.f.

input uses phono.

ICOM R7100 & R9000 receivers : The optional ICOM CT17 communication interface (or

equivalent) is required to connect between the SDU5500 and ICOM receiver. A 9-25 way

RS232 type lead or 9-25 way adapter will be required for connection to the CT17. The i.f.

patch lead will require the changing of one BNC plug as the ICOM i.f. input uses phono.

* Other receivers : It is also possible to connect the SDU5500 to other receivers which

provide a suitable (wide) i.f. output at 10.7 MHz. In fact the SDU5500 centre frequency is

programmable from the front panel of the SDU5500 when using other receivers which use

different i.f. frequencies (Kenwood, Yaesu etc) in the range of 5.7 to 15.6 MHz, however

see the note at the end of the specification... in practical terms the i.f. should be between

8.2 - 13.2 MHz for a 5 MHz span. In the case of the Kenwood TS870S set the i.f.

frequency to 8.83 MHz and span to 5 MHz, it works very well over a range of around 50dB

with good accuracy.

The CPU is FLASH UPGRADEABLE from the AOR web site with free supporting PC

control software available from the internet.
