What to Look Out For When Choosing a Digital Oscilloscope
When choosing a digital oscilloscope, experts recommend that you select the one with at least five times higher bandwidth than the maximum frequency of the signal you intend to measure.
The sampling rate is expressed in mega samples per second (MS/s) or Giga samples per second (GS/s). Sampling rate indicates the number of times per second a signal is read. Since digital oscilloscopes spend time in calculating it may not capture each signal. Therefore, it is essential you consider choosing the one with a high update rate to maximize the number of captures it makes in a second.
After capturing sample points, digital oscilloscope stores them in a memory. The memory depth defines the amount of time it can save signals before becoming full. Therefore, it is essential to choose a device with a larger memory depth.
Choosing a digital oscilloscope with more channels grants you more flexibility in viewing and debugging circuitry. This is because the higher the number of channels, the higher the number of signals can read simultaneously since each signal is fed to a different channel. However, the more channels you want to enjoy, the higher the oscilloscope is likely to cost.
Frequently Asked Questions:
What is a trigger on Digital Oscilloscope?
This is a point in which the waveform transitions to a predetermined voltage. This is also called as the trigger level.
Why would you need an oscilloscope?
Oscilloscope monitor signal voltages and helps calculate waveform characteristics such as means, peak-to-peak, frequencies and many other waveform properties for the sake of analysis.
How do you set up an oscilloscope?
The setup procedure may differ with the manufacturer. However, most of the oscilloscopes come with detailed instructions on how to set them up.
Generally, working with digital oscilloscopes is more advantageous than the analog scopes. Before you select the right digital scope for you, it’s essential to ensure that it possesses all your target features.
