SynthUSB3 USB RF Signal Generator

The SynthUSB3 thumb drive-sized USB RF signal generator is designed for an extremely high quality to cost ratio.  These devices have set the bar on microwave radio frequency generators for quality, size, and price.


The Windfreak Technologies SynthUSB3 is a 12.5 MHz to 6.4 GHz software tunable RF signal generator and frequency sweeper controlled and powered by a device running Windows, Linux, or Android via its USB port. The SynthUSB3 also has nonvolatile on-board flash memory so it can be programmed to fire up by itself on any frequency, power, sweep or modulation setting (and combinations thereof) to run without a PC in the field. This makes for a highly mobile, low power, and lightweight solution for your RF signal generation needs.
