Multi -functional transformer frequency response characteristic parameter testing appearance based on virtual instrument technique

The utility model discloses a multi -functional transformer frequency response characteristic parameter testing appearance based on virtual instrument technique, include: (1 )The FPGA parallel processing unit is including digital frequency synthesis module DDS and high -speed sampling module, (2 ) waveform processing and output unit for receive the test signal that digital frequency synthesis module DDS sent, and become the voltage source output that has bearing force after carrying out waveform processing, export the transformer that awaits measuring to, (3 )PC virtual instrument platform, a plurality of calculation module of internal integration for control command to FPGA parallel processing unit is sent to the external input test parameter, receives all kinds of data of high -speed sampling module output simultaneously, carries out exporting after the assay final result. The utility model discloses greatly improved work efficiency, reduced working strength, mainly embodied and need not carry many sets of equipment at the when used to the error and the work load of reducing coupling line.
