ALL set. CMD must be launched as system32, otherwise it doesn't work.Lesson learned. |O |

So it looks like today my firmwares have magically reverted back to the original version 2 on their own. Everything is still unlocked at it still says 300mhz. :-// Anyone else have this happen? *EDIT: I found out why... When i go into the full firmware version menu using the f7,f6,f7,utility key sequence it lists different firmware versions. Kinda weird... |

Just checked the hacked scope bandwidth with avalanche pulse generator and I read rising edge as low as 740ps! This makes the bandwidth around 470MHz. Fantastic. Many thanks to those who made this hack to happen. |

I've tried using the windows program to get the license keys, but it keeps telling me "License unavailable". I just got it today and have already used up a sizeable portion of my trial licenses playing with it, so I am eager to see them all unlocked. Scope Specs: Model: DS2072A Serial: DS2D1546xxxxx Software version: 00.02.01 Hardware version: 2.0 Looking at it again though, it seems I have to get my unique private key? I'm slightly lost and this forum thread is way too large to dig through the entirety of... --- End quote --- 300M KEY License unavailable? Give it a try 200M All KEY |

However, as a result of that, one must exercise caution... unless you only use one channel at a time, and sample at the full 2 GSa/s rate. Ignoring that could lead to wasting time chasing a ghost signal that doesn't exist, but is simply an artifact produced by aliasing. Also, these aliasing components can distort the waveshape of lower-frequency signals. If the slope of the skirts on the Rigol filters were steep enough, you could get away with up to 400 MHz inputs, with 2-channels running at 1 GSa/s. Unfortunately, they're not... and you can't. |
