An Alternative Method to Identify the Total Isotropic Sensitivity of Devices under Test in a Reverberation Chamber

Abstract

This article proposes an alternative method to estimate the total isotropic sensitivity (TIS) of a device under test (DUT) in a reverberation chamber (RC). To improve the measurement efficiency of the conventional TIS RC method, we fully utilize the received status (connected or failed status) of DUT and the statistical properties of received power to obtain the TIS without power-tuning and repeating measurements. Additionally, a multiprobe RC is used to accelerate the measurement process. Compared with the conventional method in the RC, the proposed method achieves a mean error of 0.34 dB and reduces measurement time greatly. The Monte Carlo method is used to solve the essential correction coefficient. Estimated values and relative standard deviations are provided for different output powers from the vector signal generator.
