Ka/Ku frequency band satellite intermediate frequency loop equipment and method

The invention discloses Ka/Ku frequency band satellite intermediate frequency loop equipment and a method. The method comprises a control module, a power supply module, a display module, a key module, a switch switching module and an equipment working module, the control module is used for controlling the power supply module, the display module, the key module, the switch switching module and the equipment working module; the power module is used for supplying power to each module; the key module is used for being matched with the switch switching module to determine the working mode of the equipment working module; and the display module is used for displaying the working mode of the Ka/Ku frequency band satellite intermediate frequency loop equipment. The device is used for signal switching between the C-band splitter/combiner connected with the satellite master station and the Ka/Ku change-over switch, the practice of a Ka loopback mode, a Ku loopback mode and a straight-through mode is met under the condi
