The method that the present invention obtains multichannel by random waveform generation systems is:
(1) generation of system precision clock signal adopts an External Reference clock 21, the clock signal of this clock and multi-frequency trigger signal to be carried out hybrid coding be converted to optical data stream by clock and multifrequency signal coding module 22, and this data stream is propagated to each AWG (Arbitrary Waveform Generator) 3 with the form fan-out of optical data stream by data streamer fan-out modular 23.Optical data stream recovers module 31 by clock and multifrequency signal and realizes clock and trigger signaling protein14-3-3, and is input to random waveform digital coding module 33, phase demodulation and controls in module 38；
(2) clock signal recovered generates the clock signal of high frequency by phaselocking frequency multiplier 37, and the high-speed A/D converter 35 for AWG (Arbitrary Waveform Generator) 3 provides work clock；The clock signal of high frequency produces the work clock of data range multiplier 34 by the first frequency divider 391；The clock that the clock signal separated by the second frequency divider 392 is identified as multi signal phase place；
(3) after the multi-frequency recovered triggers the delay of signal elapsed time and drive amplification module 32, it is input in random waveform digital coding module 33, starting Wave data reading program, the Wave data being stored in flash storage begins at and carries out first time parallel-serial conversion in random waveform digital coding module 33 with promoting transmission rate；
(4) random waveform digital coding module 33 exports differential pair signal in data range multiplier 34, promotes through parallel-serial conversion again and is input in high-speed A/D converter 35 after speed.DDR sampling (front and back along sampling) mode of operation of high-speed A/D converter 35 has doubled data rate again, is finally reached the target of output high bandwidth.There is intrinsic ripple in the output waveform of high-speed A/D converter 35, after low pass filter 36, output waveform is neat, the random waveform pulse of high s/n ratio；
(5) work clock of high-speed A/D converter 35 produces a clock after twice frequency dividing, exports the sampling discrimination of clock for clock and multifrequency signal are recovered module 31.When identifying phase place and being inconsistent, phase demodulation and control module 38 will export a reset signal in the first frequency divider 391, carry out the replacement of data range multiplier 34 work clock；
