Abstract

This invention discloses a multichannel arbitrary waveform generating system. The generating system comprises a computer control module, a precise time sequence generating component and an arbitrary waveform generator; the precise time sequence generating component comprises an outer reference clock, a clock and multi-frequency signal encoding module and a data flow light fan-out module which are connected sequentially; the data flow light fan-out module is connected with the arbitrary waveform generator; the computer control module is connected with the arbitrary waveform generator, the clock and multi-frequency signal encoding module, and the data flow light fan-out module; and the arbitrary waveform generator can be used independently, and also can be extended according to the requirement to form an array of dozens of arbitrary waveform generators. By utilizing the generating system provided by this invention, the data flow containing a clock signal, a menu signal, a time delay signal and so on, is transmitted at a high speed in the form of light; thus, the delay-controllable and picosecond-jittering high-speed arbitrary waveforms with optional repeated frequencies can be outputted in multiple channels.

Description
