An overview of the project for those who want to know more

At the core of the scopes there is hardware and software. The Welec W2000A series oscilloscopes are a basically good performance scopes at a reasonable price but the firmware does not have a good reputation and the hardware could benifit from improvements. Development is done in this project for both sides: the project aims at developing better firmware and software for the scopes, to improve functionality, usability and performance and also to improve the hardware.

Software

The core of the scope is the FPGA and its code. The development in this project is done essentially along two lines; one for the current FPGA code, one with a new FPGA code:

• Based on the available FPGA functionality, adding a new firmware to the scope. This adds a better user interface and functionality to the scope, based on the FPGA code developed by Welec with it's limitations and flaws. The currently released firmware here is developed along these lines.
• Rewriting the FPGA from the core and adding a new firmware to it. This is the Leon3 project and wherever you see something about FPGA design. The reason for rewriting the FPGA code is that the originally developed code is not available from Welec, so the FPGA code is essentially undocumented. This project branch is not yet available for end users and no end user firmware is available so far (may-2010).
• Development is also done of the PC software for the scope

Hardware

There is also development on the hardware side, to improve it's performance and functionality. None is yet suitable for other than involved developers, not regular end users yet (may 2010)

• There is extensive work done to improve the analogue input section and AD converters, ie changes in the hardware interiors.
• Other oscilloscope modifications for interfacing, for example addition of a board that enables screen dumps to a USB stick.
