Abstract

The invention relates to the field of signal simulators and discloses an intermediate-frequency signal panel with the memory function. According to the intermediate-frequency signal panel with the memory function, a VPX 3U board card is taken as a carrier, an NAND Flash memorizer and an EEPROM memorizer are arranged on the carrier so as to store output signal waveforms and working parameters, in this way, the output signal waveforms and the working parameters of the intermediate-frequency signal panel are not lost when a power failure occurs, manual operation is not needed after power is recovered, continuous outputting of preset analog signal waveforms is achieved, and operation complexity is lowered.

Description

technical field [0001] The invention relates to the field of signal simulators, in particular to an intermediate frequency signal board with a memory function. Background technique [0002] The signal simulator is the signal generating device of the complex electromagnetic environment simulation system, which converts the simulation results of the software system into real signals through the simulator. The simulator can generate electromagnetic background signals at any point in space, or specific communication, navigation, radar and other signals, and send it to the space with an antenna or directly inject it into the device under test with a cable to complete the simulation system function. Among them, the core component of the signal simulator is the intermediate frequency signal board, which receives the parameters of the operating frequency point (including the operating frequency, amplitude, signal form and baseband data from external devices through the PCIE (Perip...
