An oscilloscope is an instrument used to observe the waveforms of electrical signals, and is usually used for testing and analysing voltages, currents, frequencies and so on. It is one of the commonly used instruments in the field of electronic measurement by displaying the change of amplitude of an electrical signal over time, which can visually present the waveform, amplitude, frequency and other information of the signal.
Oscilloscopes are usually composed of control panels, displays, input ports, trigger circuits, etc. Depending on the application needs and performance requirements, there are various types of oscilloscopes, including analogue oscilloscopes and digital oscilloscopes.
The application of touch screen on oscilloscopes has the following advantages and features:
Intuitive operation: touch screen can provide an intuitive operation interface, users can touch the screen with their fingers to make waveform adjustments, measurement settings and other operations, making the operation more convenient and intuitive.
Space saving: Compared with the traditional button control, the touch screen can reduce the number of physical buttons on the oscilloscope, saving the space of the equipment and also reducing the possibility of component failure.
Multi-touch control: The touch screen supports multi-touch control, which can zoom in, zoom out, pan and other operations, improving the observation and analysis efficiency of waveforms.
Strong customisation: The touch screen can flexibly design the interface layout and function buttons according to the needs, adapting to different measurement scenarios and user requirements.
The touch screen applied to the oscilloscope needs to have the following characteristics:
High sensitivity: The touch screen needs to have high sensitivity to quickly respond to the user's touch operation and accurately deliver commands.
Durability: Oscilloscopes are usually used in engineering sites or laboratories and other environments, the touch screen needs to have a high resistance to abrasion and pollution, and be able to work stably for a long time.
High-definition display: the touch screen needs to provide a clear display to ensure that users can clearly see the waveform and parameter information.
Anti-interference ability: Oscilloscopes usually need to work in complex electromagnetic environments, the touch screen needs to have good anti-interference ability to ensure stable touch operation.
