  The ion beams extracted from an Electron Cyclotron Resonance (ECR) ion source always exist strong transverse coupling effect that is caused by the field of the axis mirror magnets and the extraction solenoid. A Pepper Pot probe was developed and used to obtain the full four-dimensional phase space distribution of the low energy beam extracted from the ECR ion source at IMP. This paper describes the design of the Pepper Pot, the setup configuration, the detailed image processing procedure, especially the analysis results verification compared to another type emittance meter. The first four-dimensional emittance is also determined through the Pepper Pot probe. The transverse phase space distribution measurement data of oxygen beams from the LECR4 experimental platform are presented and discussed.
