Description

technical field [0001] The invention relates to the technical field of optocoupler testing, in particular to an optocoupler testing device with low cost, multiple detection parameters, and improved product quality and detection efficiency. Background technique [0002] Optocoupler, also known as photoelectric isolator, generally consists of three parts: light emission, light reception, and signal amplification. It uses light as a medium to transmit electrical signals. Optocoupler includes light emitter and light receiver. The light emitter and the light receiver are packaged in the same shell. When the input signal is powered, the light emitter emits light, and the light receiver generates photocurrent after receiving the light. The photocurrent flows out from the output end after further amplification, thus realizing the "electricity Light-to-electricity conversion. Due to the large number of electrical parameters of optocouplers, it takes a long time to build circuits one...
