    • Abstract
  • In order to investigate the selection criteria of sweep interval and stirring bandwidth in a linear-sweep frequency stirring reverberation chamber， the stirring principle of linear-sweep mode is analyzed.Based on the over sampling principles in reverberation chamber(RC) test， the upper limit of sweep interval is determined by calculating the number of independent samples in a given bandwidth.Besides，the lower limit number of independent samples in a stirring bandwidth is given by considering the relationship with confidence interval of average field.In a large dimension RC， the S21 parameters are measured at 200 MHz，500 MHz and 1 GHz.By dealing with the data，the appropriate sweep interval and stirring bandwidth are given.Finally， the data in different stirring bandwidth are averaged， and the compared results show that the selection method is reasonable.Additionally， it is also proved that with the frequency increasing， the sweep interval and optimal stirring bandwidth is reduced.
