What DODOULTRA does
Using hetherodyne system, sampled signals are digitally processed, having so a low noise, moreover the sine wave to be multiplied is digitally synthesized (DDS). The result is a further precision than that obtained in analogic systems.
The frequency shifting comes in a fully digital way.
The frequency translator offers a lot of advantages than the classic frequency division. Signals reproduced is not calculated on zero crossing basis but the main frequency and his amplitude is digitally computed, by DSP, and a new proportionally lower frequency wave is produced using a precise sine wave generator.
The graphic display offers a wide datas visualization.
Users interact with this device using a precise and simple encoder, a wiper to change functions and setup.
Its low power allow the use of non rechargeable batteries easy to be replaced.
