The DI-2200 is a dual-channel real-time FFT (Fast Fourier Transform) analyzer that is capable of measuring, processing, displaying and storing a wide range of analysis functions. This, combined with its portability, rugged structure and ability to operate from its internal NiCd batteries, makes the analyzer equally suitable for use in the laboratory or in the field. It can operate as a stand-alone instrument or can be interfaced with a variety of printers, plotters and PCs, either for subsequent data analysis or for remote control of the analyzer functions. It is ideal for noise and vibration analysis but it can also be used for a variety of other applications. It is capable of accepting analog inputs from a variety of transducers, processing the incoming signals and displaying the results on the analyzer’s display screen. Processed functions can then be printed on a graphic or laser printer or downloaded via the analyzer’s RS232 interface to PC for archiving or further processing. Where required, the RS232 interface can also be used to connect to a host computer for remote control purposes. The analyzer’s PCMCIA memory card slot enables data to be transferred to/from a PC or to load application-specific firmware into the analyzer.
