SDS 200A

Here you can find an attempt of trying to reverse engineer the Softscope SDS 200A oscilloscope for Linux. This repository consists a first version of a driver, the tools we used to understand the usb transfers, and a documentation about what we already have or have not found out.

The driver already supports the following features:

• Reset the device
• Read eeprom data
• Set relays
• Set voltage offsets
• Set tigger offsets
• Acquire data

Driver

An incomplete driver implementation can be found in the lib directory. The source code should be documented very well. It can be used under the terms of the GPL. Additionally you can find a small documentation here.

Documentation

We offer the documentation of what we could figure out. It can be used under the terms of the GFDL. You can find more information about this device at other places.

We provide the following documents:

• Configurations: What to send to the device to configure it. You can also find the typical startup sequence there.
• Data format: How to interpret the data that the device returns in a bulk request.
• Reading EEPROM: The device has an internal EEPROM that can be accessed.

Tools

The tools directory contains tools we wrote for reverse engineering. A short description for every tool can be found here. You may use them under the terms of the GPL, too.
