A self-test apparatus for emission power of an emitter

The utility model relates to the field of wireless emission of weapons, and relates to a self-test apparatus for emission power of an emitter. The self-test apparatus for the emission power of the emitter comprises an emission apparatus and a weapon system task machine. The emitter is in signal connection with the weapon system task machine. The emitter comprises a power amplifier, an emission antenna, a transmitter master control, a coupler, a wave detector and a comparator. The coupler is connected behind a power amplification circuit of the power amplifier. One path of radiofrequency signals output by the coupler is sent to the emission antenna to be subjected to emission, and the other path of radiofrequency signals output by the coupler is sent to the wave detector. The wave detector converts the radiofrequency signals into wave detection levels and sends the wave detection levels to the comparator. The comparator also receives reference level signals mainly controlled by the transmitter. The comparator sends signal comparison results back to the transmitter master control. The transmitter master control periodically sends signals to the weapon system task machine. According to the utility model, after installing a weapon system on the emitter, real-time monitoring of emission power states of the emitter can be carried out, thereby effectively simplifying test procedures and shortening test time.
