This paper mainly studies. single event transient (SET) of a digital to analog converter produced in China. The tested device in the paper was irradiated with different particles
and the output of the DUT was connected to an oscilloscope. If a SET occurs
the oscilloscope would capture it and save its data. The test results show that with increasing LET of particles
the SET is more obvious
the times of SET is larger and the pulse width of SET becomes wider.
