ASK/FSK frequency differential detectionQ: How to use?A: Simply place the remote control on the "RF" block and press the button on the keychain, the signal will be sent to the K3 tester, and the digital frequency will be displayed on the LCD screen.Q: is the frequency of the remote control key always different?A:Rolling code technology: Most modern car remote control keys use rolling code technology. This means that every time you press a button on the remote control, the signal sent changes. This technology is designed to improve security and prevent signal interception and replay attacks. Each time a button is pressed, the remote generates a new encrypted code that has a mathematical relationship to the previous code but cannot be predicted by an eavesdropper.FM: Although the operating frequency of the remote key (such as or 433MHz) is fixed, frequency modulation technology is used when transmitting data. This means that the actual transmitted signal will undergo slight changes around the base frequency to encode different information. This modulation makes the transmitted signal sound different every time.Package Contents：1 * K3 Tester
