OWON SDS Oscilloscope Control

This project provides a Python-based GUI for OWON SDS series oscilloscopes, enabling SCPI command set via LAN or USB. It features commands for instrument control, waveform acquisition, measurement, and data export.

Features

• Connect to OWON SDS oscilloscopes via LAN or USB
• SCPI command support for instrument configuration
• Download and parse waveform data (binary protocol)
• Waveform plotting with matplotlib
• Query and display measurements (frequency, voltage, timing, etc.)
• Save waveform data as CSV or JSON
• Auto-refresh and continuous monitoring (SLOW)
• Channel controls: display, scale, coupling, probe, vertical offset
• Timebase, trigger, acquisition, and memory depth controls

Requirements

• Python 3.7+
• tkinter
• numpy
• matplotlib
• pyserial

Usage

1. Install dependencies: pip install numpy matplotlib pyserial
2. Run main.py to launch the GUI: python main.py
3. Connect to your oscilloscope and use the GUI to control, acquire, and save data.

File Structure

• main.py - Main application and GUI
• owon_controller.py - SCPI and binary protocol controller
• waveform_data.py - Waveform data parser
• scope_gui.py - Additional GUI components
• console.py - SCPI console to talk with the scope

Notes

• I have tested it on a SDS6202 oscilloscope through LAN. To be able to ping it I had to change the default MAC address. I have not tested it with newer Owon scopes!.
• The SCPI implementation in Owon is buggy, with little or outdated documentation. The connection often times out and then I have to reconnect.
• LLM have been used to help build this app. Mostly Deepseek and Copilot.
