| Abstract: | The operating process of the Discharge Trigger Controller 3All is discussed in details, and the electronic circuits, and the corresponding protection functions with the functional block diagram are analyzed. The test method of key point waveforms is described and the relationship of the trigger control signal and protection signal to sample feedback signal is clarified. The adjustment methods of the relevant working point are introduced in tabular form. From the radar system maintenance experiences, some basic electronic trouble shooting thoughts and effective maintenance methods are discussed and summarized with the relevant alarm massages and the corresponding case analyses. |
