V. How to check the fault location of remote receiver


If the anti-theft system of the remote control is too close or the remote control does not work at all, we need to check whether the remote receiver circuit is faulty. To ensure if the remote receiver is working properly, the commonly used method is as follows.

(1) Place the spectrum analyzer close to the receiver and charge the anti-theft system (or the remote receiver). In the frequency band of 200 to 400 MHz, a wavy (reduced) or reversed (inductance) spectrum waveform should be observed. If there is no response on the spectrum analyzer screen, the receiver circuit is faulty.

(2)Use the remote control to transmit signals. Use the oscilloscope to observe the output of the receiver (OUT). The input of the decoding circuit should have a pulse signal output. Due to the different data signals sent, the waveform is a combination of different widths and widths. If the waveform is not normal or the waveform cannot be measured, it indicates that the remote receiver has a fault.

(3)Observe the signal output end of the remote receiver with an oscilloscope. Use a metal object to touch the antenna of the remote receiver. The oscilloscope should have a strong clutter response. Otherwise, it indicates that the receiver is faulty.

(4)Use a remote controller to transmit signals. Measure the voltage of the signal output terminal with the DC voltage of the multi-meter. When pressing the button of the remote control, the voltage of the output terminal should be changed. If there is no response, the receiver circuit is faulty.
