This also makes sense since the CPU needs memory to run the firmware in. Both are open source and seem to be more oriented towards the linux society, with no binary files available, also both are using the USB interface. Owon scope needs to have a manually assigned IP to be able to accept TCP connection from PC you have to configure it on the oscilloscope. At the time I checked, the link to the firmware update for my oscilloscope on the Owon site was dead: Still, it has been very useful. You can check out the following code:

All the good stuff of the analog frontend AFE is hidden beneath a shield that Softwaree would prefer to not remove if I can avoid it. The scope is pretty crappy in some ways though.
I have a much fancier, and of course much more expensive, Hameg scope at the office. The next step was to try to identify the main components on the board and get a general feel for softwarf they work together. December 12, at When I connected a USB-serial adapter those pins, set sds712 terminal program to bps and powered on the oscilloscope I got the following output:.
Still, it has been very useful.
What is reverse engineering? To the left of the CPU is metal can which has The specifications for the scope are rather nice: This matches the specifications for the scope and also makes sense. The Hameg has a better analog section, the noise is noticeably lower than with the OWON, it has a higher sampling rate, can decode a bunch of different protocols, has a logic analyzer, and has more math functions than I can shake a soldering iron at and is just better in so many ways.
Hacking the OWON SDS Scope
A word of warning here. IMHO the cause and solution is:. You can check out the following code: Before packing up I just had to try something first.
So far so good. It was spftware to call it a day. I decided it was simpler for me to translate the owon-dump to python and change the interface to TCP than to try to port the programs and compile them under windows.
Hacking the OWON SDS7102 Scope
There is a huge thread discussing the SDS on EEVblog forums and other people has done quite a bit of reverse engineering of it already. The next step was to decode the BIN file and produce some processable data.
January 4, at I tried probing the four pins above the SoC. Disassembling the scope Where to start? In the top left corner there are ten more pins for a pin header which is probably for a JTAG programmer. Responsive Theme powered by WordPress.
This means that it ought to be fairly easy to make them work. When I connected a USB-serial adapter those pins, set my terminal program to bps and powered on the oscilloscope I got the following output: Being able to run the scope off the battery is also a real plus in some situations. Owon scope needs to have a manually assigned IP to be able to accept TCP connection from PC you have to configure it on the oscilloscope.

Next to it is a metal can which is marked Softtware The ethernet controller is an external component, but the pins of the IC are exposed so it should be fairly easy to probe them and figure out how they are connected to the SoC.
Both are open source and seem to be more oriented towards the linux society, with no binary files available, also both are using the USB interface. I opened up my scope and started removing parts until I found the main board which contains all the smarts.
