ERASYNTH MICRO – AN OPEN SOURCE RF SIGNAL GENERATOR




ERASynth Micro is an open source signal generator with impressive features. Everyone can afford it, including makers, hackers, students, ham radio and SDR users. ERASynth Micro can be powered from a USB port and features an LCD interface for standalone use without a computer or phone. It can generate low phase noise RF signals from 12.5 MHz to 6.4 GHz with a dual PLL architecture.

Makers/Hackers:

RF signal generators are expensive pieces of test equipment mainly used by pro engineers. ERASynth Micro aims remove the cost barrier and make quality RF signal synthesis accessible to everyone, especially the makers.

Students:

ERASynth Micro is for everyone who wants to learn how signal generators work. Since it is open-source and open-schematics, students or anyone who is curious about the inner details of signal synthesis can benefit from ERASynth Micro. You can learn a lot more by reverse engineering and hacking than you can learn in an entire year of a $50k/year engineering school. Learning about the design of test equipment turned Jim Williams into one of the best analog engineers in the world. ERASynth Micro’s advanced design will certainly teach you several RF tricks.
