Access to an RF signal generator can sometimes be a little tricky for electronic enthusiasts and developers due to the cost implications. ERA Instruments is hoping to change this with the launch of their affordable open source RF signal generator in the form of the ERASynth Micro. RF signal generators are normally expensive pieces of test equipment mainly used by professional engineers. The ERASynth Micro has been specifically designed for makers to remove the cost implications and provide a quality RF signal synthesis accessible to everyone.
