Oscilloscopes have many different names: digital storage oscilloscopes or DSOs, cathode-ray oscilloscopes or CROs, o-scopes, and oscillographs. Regardless of which name you prefer, these devices measure signal voltages. These voltages are then shown on a screen as wavelengths.
Preferred in industries like healthcare, automotive, electronics technology, engineering, physics, and science, hobbyists may use oscilloscopes for studying signals as well as propagation delay, pulse-width-modulated signal duty cycles, and even clock frequencies.
Which is the best oscilloscope for hobbyists? Whether you’re looking for a portable USB oscilloscope, a digital oscilloscope, or an automotive oscilloscope, we’ll review six scopes that hobbyists prefer, comparing the pros and cons of each.

Key Features To Consider Before Buying Best Oscilloscope:
If you’re thinking of buying an oscilloscope to start your hobby, here are several tips to keep in mind:
Selecting Your Oscilloscope:
With rechargeable batteries and vivid display screens, handheld oscilloscopes have their place. That said, others prefer PC-based oscilloscopes, which connect via a computer after collecting signals.
The best oscilloscopes come with probes equipped with a long bandwidth. Isolated probes are good for high voltages, while FET-amplifier probes are recommended for signal acceleration.
Many scopes have up to 16 digital channels, especially mixed-signal oscilloscopes. These also have about four analog channels. You shouldn’t buy a scope with just two channels, as you’ll often need more.
The time across the display and the sample rate comprise the oscilloscope’s memory. The scope can only hold so much memory at once. You may not get correct readouts if your oscilloscope has a small memory.
The higher the bandwidth, the more waveforms the oscilloscope can handle. Make sure the bandwidth surpasses the maximum frequency by five times for better readings.
