Learned to use this machine to understand the variation of voltage over time.

How to choose an oscilloscope

Oscilloscope: Helps visualize voltage and current value over time.

There are some super expensive oscilloscopes.

Number of channels, recommended 4 channels, with F < 2 MHZ


Oscilloscope acts like a low-pass filter.


Scaling factor (x10 or x1) for voltage.

Measuring features for calculating frequency.

Calculating for rise time is also easy with oscilloscope.

Current clamp??
