The SynthHD PRO from Windfreak Technologies is a dual channel software tunable RF signal generator and frequency sweeper that operates from 54 MHz to 13.6 GHz. The generator is controlled and powered by a Device running Windows or Android via a USB port. Its dual independent channels can be configured to run at two different frequencies, or the same frequency with different phases. The generator has a non-volatile on board memory so it can be programmed to fire up by itself on any frequency, power, sweep or modulation settings to run independently in the field. The generator is available in a compact module that measures 2.75 x 2.15 inches and is ideal for antenna beam steering applications, quadrature signal generation commonly used in image reject mixers and software defined radios.
