--- Quote from: Simon on March 19, 2010, 09:53:01 pm ---I'm getting quite enthusiastic about this thing where you can control the scope via a pc, is there any way of making use of this to setup the whole scope to the defaults you want ? say some sort of batch file ? I suppose there is also the possibility of having a uC control the scope.

You can send a list of individual commands, to configure all the settings.  Unlike the 1000B series, it has no commands to save and reload all the configuration settings at once (*LRN?, and :SYSTEM:SETUP?).  So you have to do it the "hard way", but that does let you tailor individual settings more easily.

You do know that you can create 10 custom configurations and store them directly on the scope itself, correct?  You can reload any of up to 10 Setups you've saved using the Storage submenus.  And you can save an unlimited number, and recall them by name (rather than just #0-9), to an external USB memory stick.

And, yes, the scope can be controlled by anything that can send serial text commands... via RS232 or USB.

I wouldn't be so sure.


--- Quote ---they are 4194325-byte files, which seems to me like a 21-byte header plus a 4MB firmware image.   The header is:

0000000: 4453 3130 3030 4520 2020 3032 2e30 322e 3032 2e30 30  DS1000E   02.02.02.00
--- End quote ---

That part is correct.


--- Quote ---There's no room for a hash, so you could do whatever you want to the file.

There's no room for a hash in the header, but that desn't mean that one (or a CRC) isn't embedded in the firmware images, to detect corruption or tampering.


--- Quote ---Unfortunately, this means that there's no sort of bootloader which could recover corrupted firmware, so your options would be to desolder the NOR flash holding the firmware and reprogram it using a chip programmer, or try to get the 13-pin JTAG-looking connector working.

--- End quote ---

Actually, there IS a bootloader in the BlackFins, in protected space.  But I doubt it would have the ability to read files off a USB stick.  So in that sense, you may be right that once corrupted software was loaded, recovery would be difficult.

OR, they may have a dual-image system, where they can load a 2nd set of firmware into the other half of Flash, but not toggle control over to it until it had been successfully validated.  Otherwise, once they started a reflash cycle, they'd have to blow away the original firmware first.  From which point there'd be no recovery on power fail or by the time it knew the image it loaded was bad.

That could explain how they utilize 8 MB of Spansion Flash, when the firmware only occupies 4 MB.  And during operation, the remaining 4 MB can be scratchpad space (like 1 MB for Reference waveform memory, as Andreas and Drieg pointed out).

--- End quote ---

I believe HyperTerm will let you configure the line terminator, but if not if may be easier to type ^J (that's control-J, not uparrow-J) to end a command line (a bit less clumsy way to get an LF without the ALT-nnn sequence).

--- Quote from: rf-loop on March 19, 2010, 10:48:10 am ---How many pictures we can find what are take inside PCB's from both models. If original factory made 1102 or 1052, are there differencies or are these seen differencies only revision differences. (specially in PCB just after BNC connector.)

--- End quote ---

So far, none of the DS1052E internals I've seen have the 2nd switching relay in the front-end, which the 1102E seem to have.

--- Quote from: KTP on March 19, 2010, 12:24:13 pm ---I can't imagine the R&D that would be involved in accurately counterfitting the Rigol DS1052E and getting it to perform similar to the true model, not to mention creating all of the injection molds for the various plastic components and buttons.  Then they would have to source all of the analog parts....

--- End quote ---

Well, see ATTEN (now also Siglent).  That's exactly what they do.  The insides are like a photocopy of the Rigol's.  Some people think that Rigol manufactures them for ATTEN, but they actually do the cloning themselves.  And yes, that's theft of IP, and copyright infringement.  And yes, that's China.

(But, no, that's not what anyone here was talking about.  Just making up fake labels for real Rigol scopes.)
