I don't know if anyone has tried it with this new 3.0 firmware. There is some suspicion about a firmware that was first heard of when it was posted on a free webhosting site in Russia. It has been talked about by a number of posters, unfortunately if you look at the post count of each, they do not have a long reputation as yet. There were also some posts mixed in that said other people were still getting it with v2.06.
Odds are the technique outlined
here will likely work. The DS1102E can now be found for almost the same price as the DS1052E, suggesting that Rigol finally threw in the towel. (In fact, if you look real close at the image of the DS1052E on the rigolna.com website, you will see it says "100MHz" on the front!)
