How to set the oscilloscope sample rate?
In the oscilloscope toolbar, press the parameters button, and then select Sample Time in Sampling, enter the sampling time.
The sampling frequency is set by yourself, the unit is time second, generally 0.01 is enough, special needs can be higher precision, more samples, the calculation will be slow.
In SIMULINK, the oscilloscope is often used as an output tool to show the results of the model in front of people. It displays the signals in time order on a two-dimensional axis. The horizontal coordinate of the oscilloscope represents the time axis and the vertical coordinate represents the signal strength. During the simulation we can change the settings of the axes as required.
The settings under GENERAL are as follows:
Time range: the unit is second, which determines the width of the oscilloscope's time window (i.e. X-axis). The higher the frequency of the signal, the shorter the time window. When set to auto, the display range of the time axis is equal to the whole simulation section.
Sampling: When Decimation is selected, the oscilloscope will generate an output every several input signals; when Sampling is selected, the oscilloscope will generate an output every one sampling time. The number of sampling points (period divided by sampling time) is based on the principle of being able to reproduce the signal waveform without distortion. Sampling times are usually set for either voltage or current sources when modelling, and should not be confused with the two.
Number of axes (number of vertical coordinates): by default, the number of vertical coordinates is 1, there is only one coordinate map; when the number of vertical coordinates is greater than 1, the oscilloscope is divided into multiple coordinates, and the oscilloscope has multiple output ports.
Tick lables (display labels of axes): when selecting all, it displays the labels of all vertical and horizontal coordinates; when selecting none, it does not display the labels of any axes; when selecting bottom axis only, it only displays the labels of each vertical coordinate and the bottom horizontal coordinate.
