Frequently Asked Questions - Oscilloscopes

A digital oscilloscope, often referred to as digital storage oscilloscope (DSO), is an electronic test instrument that uses digital signal processing to capture and display varying signal voltages in a digital format. If the scope has the ability to accept digital signals, it is a mixed-signal oscilloscope (MSO).

InfiniiVision Digital Oscilloscopes

When selecting a digital oscilloscope, it’s important to consider several key features that will impact its performance and suitability for your specific needs. These features determine the oscilloscope’s ability to accurately capture and analyze electronic signals, ensuring you get reliable and precise measurements.

  • Bandwidth: Defines the range of frequencies the oscilloscope can accurately measure. Higher bandwidth allows for capturing higher frequency signals without distortion, which is essential for analyzing fast electronic circuits.
  • Number of Channels: The number of separate signals the oscilloscope can measure simultaneously. More channels provide greater flexibility for comparing multiple signals and analyzing complex systems.
  • Sample Rate: The number of samples per second the oscilloscope can take. A higher sample rate provides more detailed representations of the signal, ensuring accurate capture of fast-changing events.
  • Waveform Update Rate: Refers to how quickly an oscilloscope can acquire and display successive waveforms. A higher update rate allows for better visibility of intermittent or rare signal anomalies, making it easier to capture and analyze transient events.
  • Memory Depth: The amount of data the oscilloscope can store for each channel. Greater memory depth allows for longer signal captures at high resolution, which is crucial for detailed analysis of complex waveforms.

Digital oscilloscopes are versatile tools used in various fields. Some common applications include troubleshooting electronic circuits, designing and testing new electronic devices, measuring and analyzing signal integrity, and serving educational purposes in electronics and engineering courses. They are essential for capturing and analyzing waveforms to ensure the proper functioning and performance of electronic systems.

Modern digital oscilloscopes may include features like automated measurements, FFT analysis, serial bus decoding, and advanced triggering options. These advanced features enhance oscilloscopes' functionality, making them powerful tools for a wide range of applications in electronics design, testing, and troubleshooting.

  • Automated Measurements: Modern oscilloscopes can automatically measure various parameters of a waveform, such as frequency, amplitude, rise time, fall time, and more. This feature saves time and reduces the potential for human error in manual measurements.
  • Fast Fourier transform (FFT):  FFT analysis allows the oscilloscope to convert time-domain signals into their frequency-domain components. This is particularly useful for identifying the frequency content of a signal, diagnosing issues like noise and harmonics, and performing spectral analysis.
  • Serial Bus Decoding: Many digital oscilloscopes come with built-in capabilities to decode serial communication protocols such as I2C, SPI, UART, CAN, and LIN. This feature simplifies the debugging of embedded systems by displaying the decoded data alongside the waveform.
  • Advanced Triggering Options: Advanced triggering allows users to capture specific events within a signal. Triggers can be set based on conditions like pulse width, logic patterns, runt pulses, and more. This helps in isolating and analyzing complex signal behaviors.

Digital oscilloscopes enable engineers to measure and visualize the amplitude of an electrical signal over time. This is also the reason they are generally considered time-domain measurement instruments. However, there are mixed-domain oscilloscopes that provide both time-domain (amplitude vs. time) and frequency-domain (power vs. frequency) measurements.

The precise characterization of waveforms is a critical diagnostic tool in every stage of an electronic product lifecycle, including cutting-edge research, prototyping, design, quality assurance, compliance, maintenance, and calibration.
