Aim-TTi Digital Function Generator
The Aim-TTi 20MHz digital function generator is the latestinnovation that offers a high-, direct digital synthesis(DDS) function at a significantly lower price. DDS generateswaveforms using a phase accumulator, look-up table and DAC. Theaccuracy/stability of the resulting waveform is related to that ofthe crystal master clock. When correctly engineered, the DDSgenerator offers not only exceptional accuracy and stability butalso, high spectral purity, low phase noise, and excellentfrequency agility. The function generator includes RS-232 and USBinterfaces for remote control of all instrument functions and forremotely storing instrument set-ups.
