description The invention relates to the field of circuit board testing equipment, in particular to portable circuit board testing equipment based on a VI curve. The equipment comprises an upper computer used for man-machine interaction and graphical display of a VI curve, a lower computer used for generating and filtering output of a sine excitation signal transmitted by USB communication of the upper computer, configuration of internal resistance between an output port and an input port, and recovery and processing of the signal. The equipment further comprises an FPGA control core, a minimum system of the FPGA control core, a DA circuit, an input processing circuit, an AD circuit, an output processing circuit, a JTAG/CONFIG circuit and a USB communication circuit. The equipment is arranged in a portable case, a user can move the equipment conveniently, and the equipment can be used in various scenes and various environments; meanwhile, all operations of the user are completed on the touch screen, and the operation pro
