Basic Principles of Operation

An oscilloscope works by measuring the voltage of an electrical signal and displaying it on a screen. The horizontal axis of the screen represents time, while the vertical axis represents voltage. The resulting waveform can be used to visualize the characteristics of the signal, such as its frequency, amplitude, and waveform shape.

There are two main types of oscilloscopes: analog and digital. Analog oscilloscopes use a cathode ray tube (CRT) to display the waveform, while digital oscilloscopes use a liquid crystal display (LCD) or other digital display technology.

Different Types of Oscilloscopes

There are a variety of different types of oscilloscopes available, each with its own unique features and capabilities. Some of the most common types of oscilloscopes include:

• General-purpose oscilloscopes are the most versatile type of oscilloscope, and they can be used for a wide variety of applications. They typically have a bandwidth of 100 MHz to 1 GHz, and they can measure a variety of signal types, including sine waves, square waves, and pulses.
• Digital storage oscilloscopes (DSOs) are a type of digital oscilloscope that can store and display waveforms digitally. This allows them to capture and analyze waveforms that would be difficult or impossible to capture with an analog oscilloscope. DSOs typically have a bandwidth of 1 GHz to 10 GHz, and they can measure a variety of signal types, including sine waves, square waves, and pulses.
• Mixed-signal oscilloscopes (MSOs) are a type of oscilloscope that can measure both analog and digital signals. This makes them ideal for troubleshooting and debugging digital circuits. MSOs typically have a bandwidth of 1 GHz to 10 GHz, and they can measure a variety of signal types, including sine waves, square waves, pulses, and digital data.

How to Use an Oscilloscope

Using an oscilloscope is a relatively simple process, but there are a few things you need to know to get started. The first step is to connect the oscilloscope to the circuit you want to measure. The oscilloscope will typically have a probe that you can connect to the circuit's test points. Once the oscilloscope is connected, you can adjust the settings to display the waveform you want to measure.

The most important settings to adjust are the timebase and the vertical sensitivity. The timebase controls the speed at which the waveform is displayed, and the vertical sensitivity controls the amplitude of the waveform. You will need to adjust these settings until the waveform is clearly visible on the screen.

Once you have adjusted the settings, you can use the oscilloscope to measure the characteristics of the waveform. You can use the cursors to measure the frequency, amplitude, and waveform shape. You can also use the oscilloscope to trigger on specific events in the waveform, such as the rising or falling edge of a pulse.

An oscilloscope is a versatile tool that can be used for a variety of purposes in electronics and telecommunications. For radio amateurs, an oscilloscope can be a valuable tool for troubleshooting, repair, and design. In this article, we have provided a comprehensive overview of oscilloscopes for radio amateurs, including their basic principles of operation, different types of oscilloscopes, and how to use them for common tasks.
