    The Solar Radio Spectrograph’s three antennas, installed in 1995, measure solar radio emissions from 30MHz to 2500MHz. The three antennas are: the Log Periodic Antenna, the 10M Parabolic Antenna and the 6M Parabolic Antenna, all of which receive solar radio waves emitted at frequencies between 30MHz-100MHz, 100MHz-500MHz, and 500MHz-2500MHz, respectively.
    The radio signals received by each antenna are divided into right-and left-handed circularly polarized components via Hybrid. Each polarized signal is then entered into a spectrum analyzer after undergoing a filtering process designed to reject strong artificial signals, followed by additional processing in the Low Noise Amplifier (LNA) in order to amplify the relevant signals.
    Operation software developed to safely manage observation systems, and accurately process and analyze observed data, provides automatic data collection and real-time data service for daily observation.
