6 principles for using an oscilloscope correctly

For engineers, using an oscilloscope well means getting twice the result with half the effort. Engineers who have not received professional training have many inexperienced in the details of using an oscilloscope. For example, many engineers like to press Auto Setup first, then Stop, and then Expand. In this process, many issues such as probe connection and oscilloscope range selection are ignored. This speech will share the 6 most important principles to pay attention to when using an oscilloscope. Mastering these 6 principles will help you use the oscilloscope better.

These six principles include:

Minimize quantization error: Try to fill the grid with the waveform and make full use of the ADC dynamic range .

Always be vigilant about the sampling rate: Oversample rather than undersample.

Choose the right bandwidth: The higher the bandwidth, the better.

Capture the full picture of the signal to be measured: Ensure that the time length of the captured signal includes the complete frequency components

. Minimize the influence of the probe as much as possible: Reduce the ground loop; Take into account the loading effect of the probe.

Use measurement statistics, wave denoising algorithm, and waveform special capture mode: Apply appropriately, and pay attention to their advantages and disadvantages.
