Aim-TTi Digital Function Generator
The Aim-TTi 20MHz digital function generator is the latest innovation that offers a high-quality, direct digital synthesis (DDS) function at a significantly lower price. DDS generates waveforms using a phase accumulator, look-up table and DAC. The accuracy/stability of the resulting waveform is related to that of the crystal master clock. When correctly engineered, the DDS generator offers not only exceptional accuracy and stability but also, high spectral purity, low phase noise, and excellent frequency agility. The function generator includes RS-232 and USB interfaces for remote control of all instrument functions and for remotely storing instrument set-ups.
