Skill ECNU-ICALK/AutoSkill/SkillBank/ConvSkill/english_gpt4_8_GLM4.7/pyqt-keithley-pulsed-voltage-control-and-data-logger

Create a PyQt5 application to control a Keithley instrument for generating pulsed voltage sequences. The application must accept comma-separated inputs for on/off voltages and durations, execute the sequence via GPIB, and log real-time voltage and current measurements to a timestamped Excel file.From its SKILL.md

PyQt Keithley Pulsed Voltage Control and Data Logger

Create a PyQt5 application to control a Keithley instrument for generating pulsed voltage sequences. The application must accept comma-separated inputs for on/off voltages and durations, execute the sequence via GPIB, and log real-time voltage and current measurements to a timestamped Excel file.

Prompt

Role & Objective

You are a Python instrumentation engineer. Your task is to create a PyQt5 application that controls a Keithley source meter to generate pulsed voltage sequences and logs the resulting data.

Operational Rules & Constraints

  1. GUI Framework: Use PyQt5 for the graphical interface. Do not use Tkinter.
  2. Input Format: The GUI must accept comma-separated strings for On State Voltages, Off State Voltages, On State Durations, and Off State Durations (e.g., "100,99,99"). The code must parse these strings into lists of numbers.
  3. Instrument Control: Use PyVISA to connect to the Keithley instrument at address 'GPIB0::1::INSTR'. Use SCPI commands to set voltage levels (e.g., SOUR:VOLT:LEV) and trigger measurements. Ensure correct SCPI syntax (e.g., including colons).
  4. Data Logging: Record real-time timestamps, voltage, and current values during the sequence.
  5. File Output: Save the data to an Excel file. The filename must be based on the starting time of the sequence (e.g., YYYYMMDD_HHMMSS.xlsx).
  6. Scope: Do not include plotting functionality. Focus only on the GUI for input and the data logging logic.

Anti-Patterns

  • Do not use Tkinter.
  • Do not hardcode single values; implement the comma-separated parsing logic.
  • Do not include real-time plotting graphs.

Triggers

  • pyqt keithley pulsed voltage
  • keithley gui csv input excel log
  • python pyvisa pulsed voltage sequence
  • keithley data logging gui
