you did it ? converted a DS1052E into a DS1102E ? brilliant !!! (or did I not read between the lines properly ?)
Nice work! I wonder what Rigol thinks about your clever hack.
So when will we have some instructions on how to do this ? cmon this has got to be shared
At least, the SYSTEM INFO page states so , and when you look at this I would say YES!:
- the lowpass switching diode (I did not find a SMD part with "FC" mark, but I guess now it's only a switching diode) is reverse biased with around 5V when BW limit is OFF (see diagram, it was forward biased with 100mV before...!)
- the timebase goes down to 2ns/div
- an 80MHz signal shows about the same amplitude as a 50MHz signal, a 150MHz signal is attenuated by only about 5-6dB
I am not sure, if the circuit of the 1052 and 1102 are indeed identical, but for me it is identical enough
Nice work! I wonder what Rigol thinks about your clever hack.
ok so just to point out I'm useless at programming and that sort of thing...
well they are still making a profit, infact I can't really see why they bothered doing what they did, as usual economics has gotten in the way...
Well, I though, you could read in between the lines, that I already did so - and when I tell you that I just closed the cover of my new DS1102E for the moment and now look for a schematic and/or pictures of the LA part of the 1xxxD, guess what this means.....
Fine, fine, take all the glory and girls ...
I still wonder where they're storing that info.
I dunno what's actually stored on that 24LC04; the device will power on without it attached to the board, but it hangs at the loading screen.[/li][/list]
There's an 8-pin card edge connector on the board, directly adjacent to the EEPROM. I had hoped that it was a factory programming interface for that EEPROM, but instead it's something quite different: It's the SPI master bus, and you could connect a SPI flash chip to it and the Blackfin would boot from it (according to the datasheet). If we number the pins as 1 <notch> 2 3 4 on the top and 5 6 7 <notch> 8 on the bottom, then the pins appear to be SCK <notch> MISO GND MOSI / PF2 Vcc GND <notch> BMODE0. BMODE1 is shorted to Vcc; pull BMODE0 to ground to enable booting from external SPI flash. This is probably how they program the units in the factory, and could be used to recover from a bad firmware flash.
There's also a (presumably) perfectly usable JTAG port for the Blackfin -- pinout seems to be (in order from 1-14) Vref !EMU <empty> GND GND TMS GND TCK GND !TRST GND TDI GND TDO, but I haven't tried it.
The six-pin header near the Altera chip is the programming header for the Lattice CPLD; I didn't bother trying it, presumably it's fused off.
Lemme know if you find those LA schematics, please.

Do you mean these schematics that Trevor came up with, over a year ago?
There are official last FW updates...
Surprice: later today there are not anymore these FW update files.
Yep. Here today, gone... today! That was certainly quick. Makes you wonder...
I think RIGOL is already aware of our thread - as it was announced on Hack'A'Day and at rcgroups.com - which is frequented by RIGOL people...
I was aware of this thread (see my first sentence above ), but that's only part of the story - we need to know which signal on the 40-pin header is what.
Things are more complicated on the 68-pin SCSI side, which carries the differential signals. I'd think that's what would be of interest to you.
You're absolutely right!

These comments, as well as the remainder of your ranting is complete rubbish. You have no clue what you're talking about. Sorry, Simon. Just because you "can't see why", doesn't mean that there isn't a very sound reason why. If it weren't for the ability to offer a range of products at differing price-points, many products wouldn't exist at all. Lots of manufacturers do it every day. And thank goodness for all of us.
When Rigol had their previous C-series out, do you actually think they built 4-DIFFERENT models, with different logic circuits, PCBs, and layouts for the 25 MHz, 40, 60 and 100 MHz units? Nonsense. They designed and built a single unit, with some mechanism for setting its capabilities (internal jumpers, whatever). In this case, they're doing it with software, and left a rather large door open. Not the smartest thing in the world to do, considering who they're selling to (economy-minded EE's and hobbyists).
Do you think that when Tek or Agilent or LeCroy or whoever make a _range_ of instruments available, they go through and put different quality components on each model, to justify the pricing differentials? If so, you are sadly mistaken. In this case, you're *itching about a $200 difference on 2 Rigol models. In those other cases, we're talking about $thousands. Of course, there they are a lot more clever about it.

Here is picture about RigolDS1102E and DS1052Et.
Sorry pictures quality is not good because fast snapshot...
Both Rigol get same signal from HP8161A with double output.
(outputs are not exactly same but well enough for this purpose)
Signal risetime is <1,3ns
As you can see in pictures, 1052 and 1102 have now same risetime (and simple it means also very much same BW). Later I will test with 70ps pulse and try look more deep.
I personally hope that peoples do NOT make big noise about this... specially in many different internet stores "review" articles. Rigol is not stupid (world #2 in scopes)... and maybe they make some not so nice things... and it means money.
yea they develooped one product and made two out of it simple I said that at the end of my post. I just don't like waste thats all.
the trick they pulled has only bought them a little time.
now countless DS1052e users are going to covert their cheaply bought scopes to DS1102E scopes with very little effort
Oh and chances are they do already know it has been hacked, I'm sure they have been quivering since the notion was brought up that the 1052 and 1102 are so similar that they must be the same unit with something done to the 1052 to keep it under restraint.
They will probably start working on new firmware that will anull the mod like changing the location of the information.
