Top 6 Best Entry Level Oscilloscope

For dem, der arbejder eller fortabler sig i elektroniske reparationer eller teknik, er investering i et oscilloskop et klogt valg. Oscilloskoper, også kendt som O-scopes, er værktøjer, der bruges til at overvåge spændinger. Det måler ikke kun signalspændingen, men også frekvenser, stigninger og andre ændringer, der kan forekomme.

Krav

Before you invest in an oscilloscope, it is important to first figure out your requirements. First, you should figure out where you will use the oscilloscope. This will determine the overall size, as well as the portability and durability. Measure different aspects of a signal is also a vital part of the oscilloscope. When it comes to signal, you need to consider amplitude, frequency, quantity, time, and viewing.

For example, do you know what the minimum, maximum, or general range of signal amplitudes you will be measuring are? When it comes to frequency, you should know how high the potential signal you intend to measure will go.

In addition to that, it is important to determine how many signals you want to measure at the same time. You should also think about whether you intend to measure a single shot signal or repetitive ones over a specific amount of time. Most oscilloscopes offer viewing in a frequency domain only. However, some users may prefer to have a time domain as well. That is a personal preference, but it is something worth considering as well.

Overvejelser

Once you understand your requirements, you should consider a few additional things. Analog oscilloscopes were once the only option available. Not anymore. Technological advances have given us the digital oscilloscope. While some users still claim analog is just as good, the truth is that they have become more and more obsolescent over the years. They are just not wise investments at this point. Digital oscilloscopes are not only more modern, but they offer several advantages.

For example, digital oscilloscopes tend to have higher bandwidths. This is important because experts recommend you purchase a model that can go five times higher than your expected maximum frequency. The sample rate is linked to the time requirement you determined above. For example, if you intend to measure a single shot signal, you should look for a oscilloscope that measures real-time sampling (RTS). If you are intending to measure a burst of signals, an equivalent time sampling rate (ETS) is better.

Most experts recommend you select a device that measures five times higher than your expected maximum frequency for this as well. However, some say that only twice the maximum frequency is acceptable for this as well. Memory depth is also important, but often overlooked. With enough memory depth, your oscilloscope will be able to last longer in taking signal-sampling rates before becoming full.

Resolution is directly proportional to the accuracy of your oscilloscope. For digital oscilloscopes, an 8-bit resolution is generally acceptable. (If you really want an analog, by comparison, you will need a 12- to16-bit device.) Oscilloscopes come in several forms. Handheld oscilloscopes, which are typically batter powered, are great for on the go.

However, that same battery can limit them. Oscilloscopes can be capable of connecting to your computer as well, which is often considered a better investment. Keep in mind, oscilloscopes are intended to enhance your work. Finding a unit with a great user manual or wealth of tutorials online can help make sure this complicated device does just that.

Nu hvor du forstår dine krav såvel som de overvejelser, du skal tage, når du handler efter et oscilloskop, så lad os se på nogle af de bedste enheder på adgangsniveau, der findes i dag.
