A Solar Radio Spectrometer at 5.2–7.6 GHz

The properties, structure and performance of a Solar Radio Spectrometer working at 5.2–7.6 GHz developed by National Astronomical Observatories/Beijing and Hebei Semiconductor Research Institute are described. The spectrometer has a spectral resolution of 20 MHz and a temporal resolution of 5 ms, with an instantaneous detectable range from 2% to 10 times flux of the quiet Sun. It can measure both left and right circular polarizations with an accuracy of 10% of polarization degree. Some results of preliminary observations are presented.
