A system for measuring electromagnetic characteristics of the KTM tokamak physical setup with the magnetic thermal insulation of plasmas includes primary signal-processing modules, interface converters, and data recording unit. When the input signal varies from -300 to +300 V in a 0-to 500-kHz frequency band, the reduced error of channels measuring signals from sensors is 1.5%. The system uses a channel-by-channel galvanic decoupling for protecting the equipment. The throughput of the digital data transmission channels is 100 Mbit/s per channel. The system is intended for operation with 160 measuring channels.
