Buying Guide
Bandwidth
The first thing to consider when buying a 100MHz oscilloscope is its bandwidth. Bandwidth is the maximum frequency of the signal that the device can capture. You need to ensure you buy an oscilloscope whose bandwidth is 5 times higher than the maximum frequency to be measured. It enables you to work comfortably and get accurate results.
Channels
It is necessary to determine what you intend to use the oscilloscope to choose either a 2 or 4 channel oscilloscope. However, with the 2or 4 channels device, it may not capture all the signals. If you want to use it for more advanced work, you can consider a mixed-signal oscilloscope. This channel has 2 to 4 analog channels plus 16 digital channels, making it great.
Memory depth
In a digital oscilloscope, captured sample points are stored in a memory. Before choosing a scope, you need to know how long you want to keep the data to pick the right size of the memory. For effective results, consider one with enough memory to handle your work.
Sample rate
It is also essential to look for the oscilloscope sampling rate. There are sample rates, i.e., real-time sampling (RTS) and Equivalent-time sampling. The device uses a sampling rate to reconstruct the signals. The type of signal you will measure will determine the activated mode. For ETS, it is perfect for repetitive signals, while the RTS works excellent for all signals. You need to make sure you purchase one with a sample rate that can handle your work.
Probes
Although most people overlook probes, it is also another vital feature that you need to consider. The probes should match or exceed the scope’s bandwidth. Ensure you choose a probe that will suit your needs
Resolution and accuracy
For accuracy results, oscilloscope resolution determines the accuracy of the signals. An oscilloscope with a high resolution has an accurate measurement of about 1% or more.
Conclusion
100MHz oscilloscopes are ideal for engineers since they are capable of detecting a lot of signals. These o-scopes are more superior compared to other oscilloscopes on the market. They also have a user-friendly interface and other outstanding features such as a colored display with high resolutions, making them ideal for various applications. You can use these 100MHz oscilloscopes in electronic engineering education, electronic product design, academic experiment, debugging & maintenance, industrial control & measuring, and electrical circuit function test.
Most oscilloscopes 100MHz are inexpensive, making them suitable for engineers who plan to acquire one with a low budget. When you want to purchase an oscilloscope, consider factors such as bandwidth, number of channels, sampling rate, rise time, screen quality, memory, accuracy & resolution, waveform update rate, triggering feature, and compatible probes. The above are among the best 100MHz oscilloscopes on the market, get one, and you will never regret it.
