Initialization Order:

        Now initializes all data structures (time_data, voltage_data, etc.) in __init__ before they're used

        Initializes device after UI setup using QTimer.singleShot

    Error Handling:

        Properly handles the case when no ADALM1000 is detected

        Disables the start button until a device is connected

    Device Connection:

        Shows clear status messages about device connection state

        Provides a reconnect button for manual reconnection attempts

    Thread Safety:

        Ensures all data structures exist before any thread tries to access them
