Used Oscilloscope Buying Guide 2021
used oscilloscope buying guide
For very high speed signals (> 200 MHz), passive probes begin to run into problems caused by the capacitance of the cable going back to the scope. This can be solved by investing in an active FET probe which places a buffer amplifier in the probe tip. For measuring high voltages, for example 100 V, mains and 3 phase voltages, the safest option is to use a differential isolating oscilloscope probe.
Oscilloscopes are essential tools scientists and engineers use to study the periodic behavior of electrical signals on electronic equipment. Since oscilloscopes contain costly high-quality components they can be relatively expensive to buy. Buying a premium used oscilloscope is an excellent option if you want to pick up a quality oscilloscope at a fraction of the price.
When used together, these two units allow the oscilloscope to create a graphical representation displaying signal voltage as a function of time, which is used to analyze the behavior of the signal and to identify problems and develop solutions.
The oscilloscope then uses this voltage to produce a corresponding electric current passed through a resistor. This current is converted back into a voltage proportional to the original signal. The voltage is amplified and used to drive the display of the oscilloscope. By carefully controlling the amplification and other factors, the digital scope can accurately represent standard and complex waveforms.
Bandwidth is one of the most important factors when choosing a used oscilloscope. Bandwidth determines the frequency range that an oscilloscope can accurately reproduce. The higher the bandwidth, the higher the frequencies it can display. When buying a used oscilloscope, be sure to check what the specified bandwidth was at the time of manufacture.
You will also need to connect the oscilloscope to a computer or other read-out device. It's important to remember that connectivity options may vary depending on the age and model of the used oscilloscope. Other types of oscilloscope connectivity include USB, RS-232, Ethernet, LAN, or WiFi.
Buying a good-quality used oscilloscope doesn't have to be complicated or stressful. By following the tips mentioned in this article, you can be confident that you're getting a scope that meets your needs and is in good working condition.

An oscilloscope, formerly known as an oscillograph, graphically displays electrical signals and showshow they change over time. Learn more about how an oscilloscopeworks, what they're used for andthe types of oscilloscopes.
With over 500 oscilloscopes available in our Distrelec online shop, finding the right one for your project can be overwhelming. This article is designed to guide you through the decision-making process, from selection to purchase.
Before buying an oscilloscope, especially if that is your first time, you might be wondering how an oscilloscope is used to measure frequency and voltage, how oscilloscope probes work and how it is used step by step.
Next, you will want to start comparing the key features of the different used oscilloscopes you are considering. This includes things like the prices, brand, and the condition of the used oscilloscope. With this information, you can start comparing the available models and brands to help you make a decision. When comparing the key features of different used oscilloscopes, you will want to make sure you are comparing apples to apples.
The final key step is to actually validate the condition of the used oscilloscope. This means you want to see the oscilloscope in person, inspect the condition, and test the functionality. You will likely make this step when you are still in the market to make sure you are actually getting a good deal. if(typeof ez_ad_units != 'undefined')ez_ad_units.push([[250,250],'studyelectrical_com-medrectangle-4','ezslot_8',135,'0','0']);__ez_fad_position('div-gpt-ad-studyelectrical_com-medrectangle-4-0');
Buying a used oscilloscope can be challenging. There are many factors to consider, and most of the time, used oscilloscopes are not in great condition. Thankfully, with a little research, you can find an affordable and reliable oscilloscope. When you do, we recommend you take the following steps. First, you want to know what you are looking for. Next, you will want to understand the differences between brands and models. Then, you will want to compare the key features of different osciloscopes. With this information, you will be able to validate the condition of the used oscilloscope, and make an informed purchase decision.
NASHUA, N.H. - An excellent device for testing and analysis, an oscilloscope is a must-have for many industries and applications such as RF design, general electronic circuit design, electronics manufacturing, service, repair, and more. Oscilloscopes are commonly used for:
Oscilloscopes are one of the most common pieces of equipment used for electric and electronic applications, second to digital multimeters. When chosen wisely, an oscilloscope can be an extremely reliable tool for testing and measurements, analysis, and troubleshooting. There are various kinds of oscilloscopes available, each suiting a different set of requirements, such as:
Select an oscilloscope that has multiple specialty probes for your requirements. An oscilloscope can make excellent measurements only if the probe delivers proper inputs to it. A new oscilloscope usually comes standard with a set of high-impedance passive probes. For higher frequency measurement applications, active probes should be used. For a mid-range oscilloscope, choose probes with capacitive loadings of
There are 2 basic properties to an oscilloscope. Bandwidth and the number of channels. This is the easiest way to distinguish between models and brands. However, there are many other features that are important when buying an oscilloscope. For example, whether it has enough sample rate to provide all channels with the maximum resolution or not. Because there are multiple target groups and price points for the models of all manufacturers, the purchase advice is split into three parts. This article is specifically about the purchase of an absolute entry-level oscilloscope. Previously, an article was published about the purchase of a 4 channels-entry-oscilloscoop,, soon to follow is an article about the purchase of a mid-range scope.
Handheld scopes are comparable to screenless scopes in that they are very easy to carry. However, the difference between the two is that handheld scopes can be used on their own. They do not need to have a computer or other device nearby to take measurements. With their compact shape and built-in power supply, these scopes can be taken anywhere to take measurements, but they are also great for basic lab applications. In this category and price range, 2 series of oscilloscopes are notable, one from Owon and one from Hantek. There are a number of important differences between them.Handheld scopesHandheld scopes are comparable to screenless scopes in that they are very easy to carry.
