IntroductıonDSG22GHz is a low-cost, open-sourceRF signal generator based on the ESP32, featuring a capacitive touch screen and powered via USB. It supports SCPI commands over both USB and Wi-Fi, making it ideal for automation tasks such as testing, calibration, and production line diagnostics. In addition to intuitive touch screen control, it also offers a user-friendly web interface, enabling easy operation in the field using just a phone or USB power bank.
Designed for developers, engineers, and hobbyists working with RF systems, the project is fully open source and permissively licensed, allowing use, modification, and commercial integration without restriction. Firmware, schematics, and 3D models will be published under such licenses.
What makes DSG22GHz truly unique is its exceptional low spurious and harmonic performance at this price point. In fact, there is no other product in the market that combines such clean RF output with compact size, portability, and affordability. This makes it an unmatched option in terms of price-performance, form factor, and field usability.
