Spectrum analyzer’s bulky brings challenging for user outside data acquisition, In order to achieve the system microminiaturize and mobilize, this paper proposed a portable spectrum data acquisition system based on android. Module spectrum acquisition and data display system had been separated. Microminiaturize and communicate by wireless network, displayed directly by graphic interface for user analyze and handle data conveniently. Data display system communicate with spectrum acquisition module by wireless network module and arithmetic programming of Java based on ARM embedded hardware platform. real-time data were displayed on spectral display system. Through developing software and hardware of system and experiments, the result show that system can perform data acquisition、transmission and display,implemented device mobilize、intelligent and microminiaturize.
