Based on off-the-self components, a multi-channel, multi-purpose data acquisition system with sampling rate up to 100 Msamples/s/channel is described. Except the possible image-reject filtering, the complete heterodyne receiving is done digitally, and the system can be applied for multi-nuclear MRI detection beyond 130 MHz.
