Sniffing the Rigol's internal I2C bus
IvoS:
ALL set. CMD must be launched as system32, otherwise it doesn't work.Lesson learned. |O
MikeGyver:
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...
IvoS:
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...

300M KEY License unavailable? Give it a try 200M All KEY

Yes, the BW of this scope is quite wide. 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.
