The TIDA-01084 reference design demonstrates the use of RF sampling DAC to generate continuous phase-aligned multitone waveforms. With four 48-bit independent NCOs: the 14-bit: 9GSPS DAC38RF83 can generate four CW tones placed anywhere within the first Nyquist zone or up to 6 GHz in the second.This reference design covers the theory of operations: explanation of the GUI: and directions for programming NCOs to generate the tones without the requirement of an external pattern generator. This design demonstrates an easy-to-use method which greatly simplifies and reduces the bill of materials (BOM) for continuos waveform generation.
