Abstract

PC based Spectrum Analyzer is a project which is developed by using Digital Signal Processing (DSP) technology. Today, most of people want a latest and sophisticated technology but at the same time having a function and quality that equal to the real hardware part. There are many spectrum analyzers at the market, but the price is expensive. At university, spectrum analyzer is only used by student at laboratory to do so some experiment related to the signal analysis. Therefore, university or students are not capable to buy this equipment. So, the equipment is limited and some experiment can't be carrying out. That is why, PC based Spectrum Analyzer is developed. Using the low cost and advantages of TMS320C6713 DSP board, the spectrum analyzer can produce a signal similar to real hardware output result. The signal can capture in real time from DSP processor and display it through to personal computer monitor. With the external hardware such as voltage transducer, the signal is step down until 1.5 V before entering to DSP board. After that, the signal will be transfer from DSP board to personal computer by using software. The operation software interface is written using Visual Basic software. This software utilizes a Graphical User Interface (GUI) which is more efficient in producing the output. Therefore, the GUI is designed specifically to give user more friendly operation. This PC based Spectrum Analyzer is a useful tool in education, particularly doing experiments and help students or learners in digital signal processing field.
