How to pick the right oscilloscope for your needs

An oscilloscope is used to track the evolution of a signal’s voltage. A digital oscilloscope is the second most often used piece of equipment for electronic test benches. This article covers the Oscilloscope functions and specifications, along with how to choose the optimum scope for your application.

Why Is selecting the right oscilloscope important?
Oscilloscopes are second only to digital multimeters in terms of frequency of usage in electrical and electronic applications. Analyzing and troubleshooting may be made much easier using an oscilloscope if the right one is selected. Oscilloscopes are available in a wide range of configurations to meet a wide range of needs, including:
1. Analog Oscilloscopes
2. Digital Oscilloscopes
3. Digital Storage Oscilloscopes
4. Computer-Based Oscilloscopes

Analog oscilloscopes have a greater dynamic range and sampling rate limit than digital oscilloscopes. Using a digital storage oscilloscope, you may keep track of transitory data for future use. A parallel processing ADC technology helps digital phosphor oscilloscopes collect and analyze signals in a shorter amount of time.
Digital oscilloscopes, RF spectrum analyzers, and logic analyzers are all included in a single instrument called a mixed domain oscilloscope (MDO).
To get the most out of your application, you’ll need a scope with a wide range of useful features – such as bandwidth, storage capacity, sampling rates, portability, memory depth, waveform update rate, and so on. It would benefit if you had the correct combination of components for the greatest possible oscilloscope performance.

Main points to consider while selecting a oscilloscope
For your convenience, we’ve compiled a list of things to remember when purchasing an oscilloscope.

Bandwidth
Choose an oscilloscope with a wide enough dynamic range to record your signals at their greatest frequency. Select an oscilloscope with a probe that has at least five times the maximum signal bandwidth to ensure accurate readings.

Rise time
To properly analyze square pulses and waves, you need to know how long the rise times are. Oscilloscope measurement accuracy is determined by the rising time. More precise measurements are made when the rising time is quicker.
Select an oscilloscope with a rise time less than one-fifth of the signal’s quickest rise time. LISUN has one of the finest oscilloscopes.

Probing
Select an oscilloscope with a variety of custom probes to meet your needs. It can produce accurate readings if the probe is properly connected to the oscilloscope. High-impedance passive probes are often included as part of the package with a brand-new oscilloscope.
Active probes should be utilized for higher frequency measurements. Probes having capacitive loadings of less than ten pF should be used on a mid-range oscilloscope.

Sample rate
As a result of the oscilloscope’s sampling rate, you may catch waveform details more effectively. It’s preferable to have a high sample rate since it provides greater resolution but consumes more memory.

Final thought
Identify your testing and measuring requirements before purchasing an oscilloscope. You may improve an oscilloscope’s performance by selecting one with a higher waveform update rate, more depth in the acquisition memory, and more channels. Advanced application support is also important for debugging and ensuring that the system complies with standards.
