Key Features:
- Multi-phase Measurement Sequences: Supports voltage-first, current-first, alternating, or single-phase sequences with configurable cycles, durations, and intervals.
- Selectable Ranges & Autoranging: Users can choose specific voltage or current ranges or enable auto ranging for fully automated measurement control.
- Live Data Visualization: Real-time plotting of measurements with auto-scaling and clear axis labeling.
- Interactive Dashboard: Displays live readings, phase indicators, and summary cards showing min, max, and average values for quick diagnostics.
- Data Logging & Export: Records all measurement data in human-readable format and allows exporting to CSV for post-analysis.
- Threaded & Responsive: Multi-threaded design ensures smooth GUI interaction even during continuous measurements.
- CustomTkinter Interface: Clean, modern, and theme-switchable GUI with responsive layouts for dashboards, controls, and logs.
- Event Logging: Full event logging with timestamped messages for traceability and debugging.
This tool is ideal for R&D, production, and quality assurance environments, enabling rapid, repeatable measurements with visual insights and automated record-keeping. It demonstrates a practical combination of instrument control via PyVISA, Python GUI development, and real-time data visualization for professional electronics testing applications.
