Oscilloscope & Signal generator
The Oscilloscope & Signal Generator application will turn your Red Pitaya board into a 2-channel Oscilloscope and 2-channel Signal Generator. It is the perfect tool for educators, students, makers, hobbyists and professionals seeking affordable, highly functional test and measurement equipment. It enables generating and measuring electrical signals up to 50MHz. The simple and intuitive user interface provides all the necessary tools for signal analysis and measurements. High-end specifications will satisfy more demanding users looking for powerful tools for their work benches. The application is web-based and doesn’t require installation of any native software. Users can access them it any web browser (Google Chrome is recommended) using their smartphone, tablet or a PC running any popular operating system (Mac, Linux, Windows, Android and iOS). The elements in the Oscilloscope & Signal Generator application are arranged logically and offer a familiar user interface.
Apart from the graph, there are five areas in which the surface is divided:
- Autoscale: Automatically sets up the Oscilloscope settings for the optimal display of the input signals. By pressing the button the voltage axis and time axis are set so that at least one full period of the signal will fill the screen.
- Channels / Trigger / Measuring Tools: This menu provides controls for inputs / outputs, trigger, guides, and measurements.
- Axis control panel: By pressing the horizontal +/- buttons the scaling of the X-axis is changed and thus the selected time range which is displayed in the graph. The vertical +/- buttons change the Y-axis, and thus the displayed voltage range of the signal. In addition, the setting for the time frame, trigger, zero point of the X-axis and the sampling rate are displayed.
- Channel Setting display: Indicates the scale of the Y-axis for all channels that are switched.
