Yep, it's an old (dec 2011) DS4014 hacked up with decodes and 500MHz. I do like the menus and other creature comforts it has over the DS1054Z I got started with (slightly faster UI compositing, dedicated menu hide & scroll buttons on both sides, separate channel offset/scale knobs, auto-scaling probes, 50ohm/ac/bw lights, segmented memory, 50% trig button) but unfortunately the firmware is notably crustier. For the longest time, decodes didn't work in segmented memory, now they *only* work in segmented memory. Older versions had freezing issues, newer versions have herky-jerky scrolling at 1ns/div scale. If I had payed Rigol's asking price for any of the extras, I'd be pissed: Agilent price at a fraction of Agilent quality. Unhacked, it's not really competitive in its price bracket, especially with Agisight getting serious about discount refurbs. My guess is that Rigol wrote it off and is focusing on their next iteration of professional scopes, only keeping it in their catalog so that they can claim experience in the price bracket while selling remaining inventory to the captive audience of the Chinese defense industry.
Hacked, it's pretty good, at least until the fine fellows over in the DSOX thread figure out how to hack a DSOX3014 to a DSOX3104

EDIT: oh, and ADC3 (pink) is dying -- rail-to-rail noise after a cold startup that goes away as it heats up. I'm not sure whether it's due to a bad bond wire, 3 years of the previous owner running the poor ADCs at 85C without heatsinks, or both, but Rigol wants $1k for the repair. That's fine, I got it for $1k off the sticker price on ebay, and I might even be able to make do with a $130 replacement ADC I got off taobao. It's been an adventure, and that suits me just fine, but it's not what most people are looking for in a professional scope. Look out for a post when ADC3 finally kicks the bucket and I make the swap; regardless of the outcome it's bound to be entertaining.
