| Abstract: | A nano-second order pulse signal generator was developed, its peak output voltage can be adjusted smoothly from 5 to 80 V. By using this generator, the fast effect and slow effect of a certain piezoelectric or ferroelectric sample can be clearly separated. The principle and performance of the instrument was introdnced, and the measurement result was given. |
| Keywords: | pulse signal generator piezoelectricity ferroelectricity polarization reverse |
