Design and Ergonomics
Control Panel
The control panel is designed for independent operation from the touch screen. Various shortcut buttons respond swiftly to operations, occupying less than 20% of the front area to maximize the display area. Dedicated buttons for frequently used functions allow one-press access, saving setting time. Three operation modes are supported: full touch screen, physical knobs and buttons, or a mixed operation.
The control panel features a multi-function area, dedicated function buttons (Auto, Run/Stop, Single, Menu, Capture), a horizontal system control (Scale, Position, Zoom, Unlock), a vertical system control (Position, Level), and a trigger system control (Source, Scale, Level). A dedicated second function button and a homepage button are also present, along with a power button.
Dimensions
The oscilloscope has dimensions of 280mm (width) x 180mm (height) x 50mm (depth). The front view shows the large display and control interface, while the side view highlights the device's slim profile and ports.
Main Features
