• Digital storage oscilloscope (DSO): This is a conventional digital oscilloscope and is ideal for low repetition-rate or single-shot, high-speed, multichannel design applications.
• Digital phosphor oscilloscope (DPO): A DPO takes a new approach to oscilloscope architecture and, unlike DSOs, provides Z-axis (intensity) in real-time. DPOs are the best general-purpose design and troubleshooting tool for a wide range of applications and are often used for advanced analysis, communication mask testing, digital debug of intermittent signals, repetitive digital design and timing applications.
• Mixed signal oscilloscope (MSO): A type of DSO, MSOs are designed to display and compare both analog and digital signals. It is the instrument of choice for quickly debugging digital circuits using powerful digital triggering, high-resolution acquisition capability and analysis tools.
• Mixed domain oscilloscope (MDO): These oscilloscopes provide the same capabilities as mixed signal oscilloscopes, but also offer a built-in spectrum analyzer, adding RF debugging to the analog and digital capabilities.
• Digital sampling oscilloscope: For very high-speed signal analysis, sampling oscilloscopes support jitter and noise analysis with ultra-low jitter acquisitions. It can achieve bandwidth and high-speed timing 10 times higher than other oscilloscopes for repetitive signals.

Read more about the types of oscilloscopes and the features of each to find the right oscilloscope for your application.

When it comes to choosing the right oscilloscope, there are a number of factors to consider, including bandwidth, waveform capture rate, sample rate, rise time,  triggering capabilities and price. Much like shutter speed, lighting conditions and aperture of a camera all affect its ability to capture an image clearly and accurately, the performance considerations of an oscilloscope significantly affect its ability to achieve the required signal integrity. To learn more about these criteria and how they might relate to your applications, read our deep dive on how to evaluate an oscilloscope. 

In 1897, a German physicist named Karl Ferdinand Braun invented a cathode ray tube and, along with it, the first oscilloscope, which was expanded upon decades later by the company A. C. Cossor. In 1934, the first commercial oscilloscope was released by General Radio, and it became the first to be used outside of a laboratory. And in 1946, Howard Vollum and Melvin Jack Murdock founded Tektronix, which has gone on to become a world leader oscilloscopes. Since then, Tek has continued releasing innovative new technologies, including the first digital oscilloscope in 1971 and the first oscilloscope-to-cloud software solution—TekDrive—in 2020. Oscilloscopes are a staple of any engineer’s bench and have even been featured in famous films throughout history. You can visit the Tek museum website to see a complete list of oscilloscopes in films.

Digital oscilloscopes are the key to helping engineers meet today's demanding measurement challenges. Tektronix is the world leader in oscilloscopes and offers a variety of oscilloscopes to meet the needs of even the most advanced applications.
