The invention discloses an electric power line interference signal extraction and synchronous playback device. The device is composed of a signal collection module, a signal playback module, a signal processing module, a signal storage module, a mode control module, a network communication module, a clock generation module and a control output module. Tested signals are collected by the signal collection module and are transmitted to the signal processing module for processing. The signal processing module stores the processed signals in the signal storage module and transmits the processed signals to the signal playback module. Triggering signals are input through the mode control module, so that the signal playback module is controlled by generated clock signals to output playback signals. The mode control module is connected with a network port through the network communication module. The mode control module is also connected with the control output module. The control output module is used for controlling output of state indication signals. Isolated sampling and high fidelity playback for non-working frequency signals on an electric power line are realized. The device can be applied to detection of a carrier communication function and an anti-interference capability test of a communication metering function of a meter.
