The invention discloses a simulation device with sampling deviation of fixed fraction times, belonging to the technical field of digital communication. The simulation device comprises a sending end simulator, a sending end forming filter, a channel simulator, a receiving end forming filter and a receiving simulator, wherein the sending end simulator is connected with a base band of a sender to transmit base band data; the sending end forming filter is connected with the sending end simulator to transmit deviation added data; the channel simulator is connected with the sending end forming filter to transmit base band sending data; the receiving end forming filter is connected with the channel simulator to transmit base band receiving data; and the receiving simulator is connected with the receiving end forming filter to transmit filtered data with deviation and also transmit reduced base band data. The invention respectively uses data selectors with very little resource occupation on the sending end and the re
