Is it hackable?

Yes!

(we just don't know how easy it is, yet...)

woohoo! individual channel controls!

And a single (multiplexed) cursor control knob...wah..wah..wah.

Once you have them you will never go back.

It's touch screen though. Dave never seems to get used to using his finger for menu selections but I'm sure other people will.

Above 350MHz you need active probes, etc. I imagine that's why there's a 350MHz option - you can just about use ordinary probes there.
That is nonsense. You can even build a DIY passive probe which goes to 1GHz for a few dollars worth of parts. And then there is Ebay with used probes and I'll probably be releasing a 'cheap' >1GHz differential probe soon.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

I didn't say you can't. I only said you start to need active probes at about 350MHz.

...and in marketing land that implies a big price hike (the device is now "professional").

Oh and one more comment on the video... Dave... the MSO5000 has a friggin' touch screen! Use it! Don't use the select knob and buttons at the side of the screen.  :box:
OTOH it makes me wonder if the user interface has been really designed for a touch screen like the R&S RTB2000 / RTM3000 or that it is just a touch-enabled existing user interface.

If the 2ch 70 MHz model can be hacked to a fully optioned 4ch 350 MHz with decoders then it will sell, other then that it's a dog at retail pricing.

It's competitive with competing models at the low end, but absolutely not at the higher end.

uBoot output:

Code: [Select]
U-Boot 2014.01.Rigolee.dirty (2018.06.12 - 12:12:01)

Memory: ECC disabled
DRAM:  448 MiB
NAND:  OnDie ECC supported, 1024 MiB

zynq-edac f8006000.ps7-ddrc: ecc not enabled


Has that actually got ECC memory but they disabled it?

I greatly doubt they'd use ECC memory.

Yes!   (we just don't know how easy it is, yet...)

To save people the time and trouble they should have just whacked a three way selector switch on the back with a few options.

1. Not hacked at all.
2. Hacked just a bit.
3. This thing is fully hacked.

No and no. Some NAND ROM memories have the ability to do the error correction on the chip itself (this has nothing to do with the DDR RAM memory). However you'd still need to take care of the bad block management in software. Most SoCs have a NAND controller which can do error detection & correction in hardware with a better software interface so it is easier to deal with. Doing the error correction entirely in software is also an option.

Who is best placed to do the hacking? Im sure that we could rustle up enough support to buy one to send it to the best rigol-hackery-shop we know?      I'd put in a $100 speculative to fund the entry level one, anyone else want to play?

Curious, if the 350Mhz bandwidth is just arbitoryly defined by software.

Hah, you replied to my post twice now with the same message(more or less).

I dunno, $900 for a 70 MHz 2 ch scope still seems pretty blah to me. The fact that it needs heatsinks on the front end ASIC's is also pretty lame for a newly developed chip.

The chip is capable of a few GHz. Think of the bias current required for that.

I guess it depends on how good it really is. 10 years old tech can build a front end chip good to 1.5 GHz + that has no heat sink at all.

1. Nah, bro.
2. It's lit.
3. Absolute unit.

Well at least 'pulses' is spelled right this time... -ducks and runs-  >:D
I noticed that too.

Yep, this time Rigol went for "Threhold" — three times on the same screen. At least it's consistent, I suppose. ;D

(Free QA, as usual. You're welcome, Rigol.  >:D)
I TEA.

Before hacking it needs to be checked for proper PLL functioning and power supplies oscillation.

White stuff gets really dirty really quickly. Black stuff you can't see it as bad.

Black ThinkPad here too which is really mucky but you can't see it :)

You guys do not understand, it is all about diversity. The next model will be Pink.
Or Rainbow.

Nah .... Just wait.  They'll have programmable colours you can set up in software.

His "World Exclusive" actually wasn't. Batterfly uploaded a hands-on video a couple days before he did  ;D
Dave never went back and did a review on the Siglent 1104X-e like he promised in the teardown video, so I was very happy this time he actually included a quick demonstration within the video.  As an aside I was reading the comments on this video and most are overwhelming complaints about looks and price.
I think is a great scope for the money, and love the way it looks, so don't understand all the people bashing it. The only real negative I see is I wish the screen was brighter. Like Dave said in his video it appears bright but actually isn't. In the Batterfly video you can see the screen is dimmer than what you would hope for.

OK, not about looks and price from the short demo? Well, the interface is laggy. It's got Rigol's famous, but different this time, spelling errors. Also, I hate the rectangular grid. The screen is wide, but instead of providing more horizontal divisions for looking at signals, they stretched them out to fill the space.
I TEA.
