Використання генератора сигналу dds/ppl для створення універсального аналізатора радіосигналів та інших пристроїв

Abstract

By using a DDS or PPL signal generator, it is possible to tune the intermediate frequency of a superheterodyne receiver to any desired frequency, which enables the receiver to become a powerful tool for analyzing radio signals. With this setup, one can analyze the frequency spectrum of a signal, demodulate the signal, or even decode digital signals. Additionally, by using specialized software and hardware, this device can also be used as a UAV detector or direction finder. Its versatility and potential for customization make it a valuable tool for both hobbyists and professionals in the field of radio frequency engineering.
