7、ital Device users - 36 12 Limited warranty - 36 2 1-1 Introduction Thank you for purchasing the SDU5600 Spectrum Display Unit. For many years, AOR has been marketing the worlds first color spectrum display unit, SDU5000 for professionals and the high- end of hobby listeners. The SDU5500 was a worthy

8、 successor to the SDU5000, suing a large high resolution LCD. The SDU5600 is the “next generation” in spectrum display units. Using a five-inch TFT color display, DSP (Digital Signal Processing) and FFT (Fast Fourier Transform), faster sampling rates and color imaging, the SDU5600 opens the door to

9、new possibilities and applications. To get the best possible results, we recommend that you read this manual to fully familiarize yourself with the SDU5600. Every effort has been made to make this manual correct and up to date. Due to continuous development of the product and by error or omission, a

10、nomalies may be found and this is acknowledged. This manual is protected by copyright AOR, LTD. 2003. No information contained in this manual may be copied or transferred by any means without the prior written consent of AOR, LTD. AOR and the AOR logo are trademarks of AOR, LTD. All other trademarks

11、 and names are acknowledged. 1-2 Maintaining the unit There are no internal operator adjustments. In the unlikely event of servicing being required, please contact your dealer for technical assistance. Do not use or leave the SDU5600 in direct sunlight (especially the LCD). It is best to avoid locat

12、ions where excessive heat, humidity, dust and vibration are expected. Always keep the SDU5600 free from dust and moisture. LCD contrast and brightness may be adjusted via menus, adjust appropriately to your operating environment. Note: Never push or knock the LCD screen it is very fragile and sensit

13、ive to shock. Daily care Use a soft, dry cloth to gently wipe the SDU5600 clean. Never use abrasive cleaners or organic solvents which may damage certain parts. Treat the unit with care, avoid spillage or leakage of liquids into the cabinet and power supply. Special care should be taken to avoid liq

14、uid entering around the keys, rotary dial encoder or via the connectors. 1-3 Power requirements The SDU5600 comes with a 120 V AC adapter. The SDU5600 is designed for operation from a nominal 12 V DC regulated power supply (12 to 14 V is acceptable), which should be capable of supplying a minimum of

15、 1 amp continuous, ideally a 2 amp power supply unit should be used. Note: Never connect the SDU5600 directly to an AC outlet. The DC power jack uses a mini power connector conforming to EIAJ RC-5320A and is wired center positive (+), the chassis of the unit is at negative ground. To minimize the po

16、tential for power cable interference, it is suggested that a ferrite clamp be fitted to the power cable. Safety Notice: Always disconnect the power supply from the AC outlet when not in use. 3 Should the SDU5600 appear to behave strangely, normal operation may easily be resumed by resetting the micr

17、oprocessor. Simply power off the SDU5600 and disconnect the power supply. Leave the power off for 30 seconds, and then re-connect and power back on again. 1-4 Supplied accessories The following accessories are provided in the shipping box. 1 Control cable for the AR5000 models (DB-9 type male) 1 BNC

18、 patch cable for IF connection 1 Instruction manual (this booklet) 1 120 V AC adapter Note: If used with the AR3000A receiver, a small modification is required to the receiver in order to provide the required 10.7 MHz IF output. 1-5 Features High resolution 5 inch color TFT display 5 inch TFT color

19、display graphics are clear, crisp and sharp. Color adds to the ease of use, making the SDU5600 as useful on the bench as it is in the field or as part of permanent mobile operations. Built-in “waterfall” display function FFT signal processing and analysis DSP Wide input level range 0 -90dBm High dyn

20、amic range 60 dB Fully interactive with AOR AR5000 models AR5000 models can be operated from the SDU5600 providing selection of center frequency, receive mode, etc. Any frequency spotted and monitored by the SDU5600 may be immediately received by the AR5000. Wide spectrum coverage The SDU5600 covers

21、 a maximum of 10 MHz (+/- 5 MHz) spread against the input frequency. Multiple frequency resolutions 4, 32, 64, 128 KHz Fast sampling Up to 6x per second Image output to your PC Bus signal can be saved to memory Menu driven operation All functions are accessible via dedicated keys and on-screen menus

22、. Remote control via PC All keyboard operations of the SDU5600 can be controlled by PC via RS-232C. Also acquired data can be downloaded to PC. Compatible with other receivers A receiver equipped with a 10.7 MHz IF output can provide signals to the SDU5600. The sweep span could be limited, depending

23、 on the IF characteristics of the chosen receiver. 4 2 Controls and functions 2-1 Front panel controls The front panel of the SDU5600 is dominated by the large color LCD. Controls are grouped to assist efficient operation; there are a total of 26 keys in addition to the power on/off switch and the r

24、otary dial encoder. 1 Power switch Press once to latch the switch in, switching on the SDU5600. To switch off the SDU5600, press the switch again, the switch releases outward. Downloaded by?

25、aphics 3 Special function keys Three special function keys are located under the LCD. There is no printed legend identifying the keys as their operations are defined by which menu is active on the LCD. 4 Rotary dial encoder A rotary dial encoder is provided to move the marker position, enter center

26、frequency to the unit, and so forth. 5. Main Control keys There are 20 main keys including numeric keys. Some keys have secondary functions, and the functions are printed above each respective key. To access the secondary function, press the “FUNC” key located at the top right of the control keys, a

27、nd then press respective key. 6 6. Special keys Three (3) special keys are provided with the SDU5600. Those keys are to be used for entry of center frequency, frequency span/step, and amplifier gain select. 2-2 Rear panel The rear of the SDU5600 has two (2) DB-9 connectors for connection to the comp

28、anion receiver and PC, one (1) BNC connector for IF input, and one (1) DC power connector. A blank plate covers the unused section of the rear panel, which may be used for possible future expansion or options. 1. RF IN Using the supplied coaxial cable with a BNC connector at each end, connect to the

29、 IF output from the companion receiver such as an AOR AR5000 series receiver. 2. PC I/F A computer may be connected to this connector. As the connector is identical to that used for the companion receiver connection, great care should be taken to avoid connection to the incorrect connector. Although

30、 it is very unlikely that incorrect connection could cause damage, it will cause unnecessary delay in placing the SDU5600 into useful operation. 3. RX CTR The supplied DB-9 cable is used to connect the SDU5600 to the companion receiver. 7 4. DC 12 V Connect the supplied AC adapter to this connector.

31、 If you wish to operate with 12 V external regulated power supply, it should have a minimum continuous capacity of 1 A or higher, ideally a 2 A (or higher) supply should be used. The connector complies with EIAJ RC-5320A and is wired center positive (+), outer negative (-). 3 Connection to a receive

32、r 3-1 Configuration of the AR5000 receiver Before connecting the SDU5600 to a receiver, the power switch of the SDU5600 and the receiver must be turned off. In order to control the AR5000 receiver, the following setting is required to the AR5000 receiver. Baud rate: 9600 bps External IF output: EXT

33、IF1 (Note: See details on page 29 of the AR5000 instruction manual.) 1 Connect an AC adapter to the SDU5600. 2 Connect the DB-9 interface cable between the RX CTR connector on the rear panel of the SDU5600 and the REMOTE connector on the rear panel of the AR5000 receiver. 3 Connect the included BNC

34、cable between the RF IN connector of the rear panel of the SDU5600 and the IF OUT connector on the rear panel of the AR5000 receiver. 3-2 Configuration of the companion receivers Your SDU5600 may be used with the following companion receivers.
