description The invention discloses a signal interference device. The signal interference device comprises a signal source mainboard and a data conversion board, wherein the data conversion board is used for converting the stored interference signal digital waveforms into analog waveforms through a DAC chip in a storage transmitting mode, interference signals comprise broadband multi-carrier signals, or multitone signals, or single-tone signals, or broadband noise signals, or swept-frequency signals, in the DDS mode, the multiple interference signal digital waveforms are generated through multiple DDS modules and then are converted into the analog waveforms through the DAC chip, and the signal source mainboard is used for controlling the data conversion board to switch between the storage transmitting mode and the DDS mode. According to the signal interference device, the generated interference signals are stored, corresponding interference signals can be generated when equipment is started, work can be conducted in the
