SDU5600
Spectrum display unit for use with a companion receiver.
Enhance your monitoring with visual spectrum and waterfall displays of activity up to +/-5MHz from the centre frequency, updated in real time up to six times per second. A range of receivers are supported including the AR-ONE, AR000, AR3000A, ICOM R8500 and many others. An RS232 port is also provided for PC control.
Digital signal processing and fast fourier transform algorithms combine to make the SDU5600 a very powerful spectrum display system. The result is a graphic display, and textual information, that is fast and accurate.
Interactive menu driven choices put potent analysing tools at your disposal. You can control AOR AR-ONE, AR5000 and AR8600 series receivers through the interface with the SDU5600. Control for some other receivers is also possible including the ICOM R8500. You may also engage in computer aided control of the SDU5600 and utilize a PC as an integral part of the analysis process. All this is possible through two RS-232C ports on the rear panel.
127mm (five inch) TFT colour display graphics are clear, crisp and sharp. Colour adds to the ease of use, particularly the waterfall feature making the SDU5600 as useful on the bench as it is in the field or as part of permanent mobile operation.
The AOR SDU5600 is the "next generation" in spectrum display units employing DSP and FFT (Fast Fourier Transform), faster sampling rates and colour imaging, the SDU5600 opens the door to new possibilities and applications. With sampling at up to six times per second, the operator is quickly aware of new active frequencies. The "waterfall display" function is truly a great convenience, along with a host of menu driven selections and features.
Other receivers equipped with a 10.7 MHz IF output can provide signals to the SDU5600 but the sweep span could be limited depending on the IF characteristics of the chosen receiver.
A full review was carried out in the March 2004 edition of Short Wave Magazine.
The SDU5600 firmware may be flash updated and a free PC control program is available for download.
