I’ve used the SDG1032X, the DG822 and the DS1022Z and I’d probably go with the DG811 and crack it which is fairly easy. Note that the frequency counter on all of them is dire and useless so don’t buy it for that. SDG1032X is fairly nice though but the bang/buck is off. rf-loop mentions pulse issues which you can work around by triggering the second channel off the first on the rigol by connecting a BNC cable up :) No fan is a win for me! Someone has made a 3DP cup holder for the DG8xx as well if the odd design is too much for your lab :-DD |

I always hacked my tools like oscilloscopes, but, uses same hardware dg811 than dg992? |
| bd139:
Yeah DG811 is same as DG922. When you crack it the LEDs on the panel all go red as well! |

So how easy it is - one cable? If I tell problem do you thing that I do not know what I am talking. I need one 1000ns pulse and emulate situation there is other much more short pulse and important is its timing related to this other pulse. In real system it make "window" (measured when long pulse is high) Second, short pulse position inside this 1000ns "window" is this important thing and it need simulate with generator in preliminary testing phase. And it need work even if pulse interval is 10ms or 10000s or what ever and it need be repeatedly adjust for test different cases. Bit same kind of thing, I remember one generator (Not Rigol) what was advertised it have two independent channels and then it have also modulations.... oh well... when use modulation it was 1 channel generator... because it need other channel for generate modulating frequency... so, many kind of toys. |

Well the problem is you end up having one usable pulse generator out of two channels off these cheap arbs. One BNC cable. First channel generates the trigger pulse, second channel is triggered by that and generates the output pulse. As for the window that can be pulled off the sync output for the first pulse. I’m not sure exactly what you’re after there TBH but you can get pretty creative with these after a couple of cans of red bull or cups of coffee :-DD |
