[0002] Electronic products such as set-top boxes, gateways, and remote controls require multiple tests of infrared transmission and reception angles during the R&D and production stages. When testing the transmission angle, the infrared remote control needs to be aligned with the infrared receiver and kept at a certain distance, and the infrared remote control button needs to be pressed while recording the angle change of the infrared receiver. When testing the reception angle, the infrared receiver needs to be placed at different angles and its angle needs to be recorded, and the infrared remote control button needs to be pressed while observing the response of the infrared receiver.
