Device and method for testing EOS performance of handheld terminal

The invention discloses a handheld terminal EOS performance testing device, which comprises EOS equipment, electric leakage testing equipment, a multi-path switching unit and a single chip microcomputer, and is characterized in that each switching unit comprises two single-pole double-throw solid-state relays, and the common ends of the two single-pole double-throw solid-state relays on each path of switching unit are connected with a tested handheld terminal; the normally closed ends of the two single-pole double-throw solid-state relays on each switching unit are connected with EOS equipment, the normally open ends of the two single-pole double-throw solid-state relays on each switching unit are connected with electric leakage testing equipment, and the single-chip microcomputer is electrically connected with the single-pole double-throw solid-state relays. The single-chip microcomputer controls the on-off switching of the single-pole double-throw solid-state relay so as to control the switching between the
