Dave opens up his Rigol DS1052E Oscilloscope, and ponders how to convert it into a DS1102E.
And yes, he finally checks out the infamous ADC overclocking issue.

@EEVblog what is your opinion of the screen? I saw some reviews on websites saying that the screen isn't very good. I couldn't find any information regarding this in the comments for this video. Great vblog by the way!

@mrmatz408 The screen in terms of brightness is awesome, almost too bright. Still only QVGA resolution though.

Does it make sense to replace these chips with 100MHz ones?

[EEVblog]

@crippled82 None what so ever. It's the same silicon.

[joeles69]

i got one of these of deal extreme... at 360USD.. freeking bargain!

[EEVblog]

@joeles69 Yeah, it's incredible what value these scopes give you for the money these days.

[fingerboy18]

That's interesting. That DIP looked to be rotated to about 15-30 degrees. Awesome!

[smithyduk]

Does anybody know if rigol have sorted out all the software bugs yet?

@EEvblog, great review and tear-down.

A n00b query. Would you recommend this scope for someone looking to work with some sensor network projects using MCU's with clock freq upto 60MHz (72 DMIPS), and some ISM band RF work (315MHz-2.4GHz), involving encoder/decoder IC's etc. ? All using TTL / CMOS logic.

This is just for hobby++ level work. Also, can I expect it to double up as a 2 channel LA ? This is really for a very budget constrained situation.

For the CPLD, It is very likely to be put there to off-load FPGA's buffer current to

prevent GroundBounce and ElevatedGround effect (since I believe 90% of the flip-flops inside it must be ticking, so they have enough problem with elevated ground there). Better to let the CPLD drive the clocks, and perhaps help them simplify the

board design (using less vias, less layers by letting some of the not-sensitive signals go through the CPLD).

@TheEPROM9 I second the firmware notation. Perhaps the hardware is capable of 100Mhz and it is just enabled by software so they could sell more to people who couldn't afford the 100Mhz.

[4hodmt]

How are you supposed to remove the bracket around the C14 connector? It's tightly jammed behind the plastic case.

[TheEPROM9]

The answer could be in part of the firmware and some minor component values such as resistors and capacitors. Its worth looking at if you haven't already.

there is also this 250$ Atten 60MHz scope: cgi. ebay. com/ATTEN-ADS1062C-60-MHz-2-Ch­annel-Digital-Oscilloscope_W0Q­QitemZ180588753205

would be nice to see a review of that too.
