| Abstract: | In order to realize transient measurement and signal memory, transient measurement system included high-speed A/D, DSP and FPGA is designed. FPGA controls transient measurement and acquisition, and DSP deals with data. In view of interference question in the operation environment the measures to improve the EMC of system are brought forward These measures include induction coil design, electromagnetic shield, filter technology, grounding design and PCB design. It is indicated in experiment that system can thoroughly realizes full process measurement of transient signal under operation environment with interference. |
