oscilloscope front end design


I will translate. It is pretty simple and cheap (35$) device based on new C8051F321 from SiLabs. It uses on-chip features like USB and memory to store and transfer samples, and external ADC. Features include logic analyzer (2.7 Mhz), oscillograph (200 kHz), logic generator (1.7 Mhz) and some others mode. Some additional features like signal filtration, protocol analysing (I2C, SPI, 1-Wire, UART) and firmware updates are available via PC GUI.

The scheme is here: http://www.usb-osc.narod.ru/files/shem.png
Firmware: http://www.usb-osc.narod.ru/dw_hex.htm
GUI + driver: http://www.usb-osc.narod.ru/dw_soft.htm

oscilloscope fpga schematic

Is there any personal site on internet about an osc. project ?
 

pc based oscilloscope circuits

Why do you post a website which contains only a title???
 

rangkaian digital oscilloscope

If anyone is still monitoring this topic there is a yahoo group that is working on developing a scope/analyzer maybe folks can join forces with them

search for multianalyzer

Thanks
Jay

I wonder what happened to that project? The last entry is dated 27.04.2004. and right at the moment the guy seemed to come to the working solution.

Does anybody have any news on that one?

That's my site (hi everyone!).

I was to busy with other things for several months, but recently I've started work on the DSO project again. Also on some other projects and a new website (which is why I haven't updated the old one at all).

I just gave the URL for the new site (not actually ready yet) to "lighty", so I guess I might as well post it here as well.

There is some new info there, but not a lot (yet).

Now I really have to go study, but I will do a lot more soldering and programming after my exams

@cyr

Welcome to the EDAboard (aka Elektroda) the best site for electronics!
I think you will like it here... 8)



BTW- do you have any more specs for your new version of DSO? I looked at the specs of your previous one and it seemed to be in advanced stage of development both hardware as well as software.


Now if your project could be taken as a basis on which to build more advanced model it would be great because it would give a great boost to the current projects mentioned in this thread that are in more immature stage of develpment. It is of course my private wish only and maybe something that cannot be easily done. :wink:

Why you use ethernet controller, instead of USB?

triggering dso vhdl


Mainly because my laptop has 54Mbps WLAN but no USB2.0

I prefer to plug the scope permanently into my LAN and then have access to it from any computer, and wirelessly. No special device drivers are needed either.

Even so, since I have the ethernet controller on a separate board it wouldn't take all that much work to replace it with some USB2.0 chip if I should change my mind.

I can advice you to look on DASP technology, for this project. Somethere i read that guy cover 1.2GHz bandwith with 80MS/s ADC. Not sure about, but somthere it was.
If u are interested in it i can help a little bit in signal processig field.
Main idea is quite simple, make readings, with frequency smaller than it is needed according to nyquist criteria. But time between readings is randomized.

hi folks i also like to make this project with pci bus.so what will be the maximum speed with that?and how can i make the inputs for the probes?
 

dsoamk3

I think you should have a memory buffer before the pci-bus to maintain constant sample-rate, then the pci-speed doesn't matter much. The probe-inputs is a part of the difficult analog part, take a look at some of the links in this thread...

HI,
I have tried for weeks now to access either

I have tried with Opera and Mozilla Firefox.
Could somebody help please?
Thank you

I got the same problem. Can anyone post the schematics here?
