Introduction
Revision D of the design is a major change from revision C, with real-time waveform playback, improved control loop performance, and better DFM.
Design
Similar to revision C, the user's computer communicates with the current driver box: a single digital control board which interfaces with multiple (up to 8) 8-channel amplifier boards, each containing a DAC for setting output current, an ADC for monitoring output current, and 8 copies of the analog control loop and power amplifier. Each amplifier board consists of two sections: a power section mounted to a heatsink, and a control section mounted to the power section. Power outputs run over ribbon cables to an ODU-MAC White-Line connector for connecting the shim coils. (Block diagram)
