Abstract: The improvement of digital system of DNP spectrometer and establishment of a new system of transmission and receiver are introduced in this article. The π/2 pulse width is less than 5μs, which meets the requirement of CP and high power decoupling. The DNP enhancement curve can be obtained automatically.
