In recent years, digital excitation adjustment has gradually become mainstream of synchro-generator excitation adjustment with the replacement of simulated excitation adjustment.

近年来，数字式励磁调节器已逐步取代模拟式励磁调节器而成为同步发电机励磁调节器的主流。

The 14-bit, four-channel A/D converter MAX1325 is employed to sample the analog input and output voltage of the synchro and then converted them into digital.

模数转换采用了14位，四通道A／D转换器MAX1325，实现了自整角机四路模拟数据的同时、快速采样。
