Why us?

In this blog, we will be shining the spotlight on what we believe to be the very best oscilloscope brands on the market today. All of the items that you will see in the list below can be bought right now courtesy of the distributors that we work with here at OEM Secrets. But what makes them so special? Well, we will be explaining:

· How each of these items appears visually

· What the standout features of each of these products are

· How the item performs in line with industry expectations

· The most significant pros and cons to look out for

· How our customers feel about each of the products

However, it makes sense to start by explaining what oscilloscopes do before we delve into what the best examples of this product range are. Therefore, let’s start our article on the best oscilloscope brands right now!

What is an oscilloscope?

So, an oscilloscope has a variety of names, such as an oscillograph and an o-scope. It acts as a form of electronical text to provide a graphical display for a variety of signal voltages. This generally occurs in the form of a calibration of two-dimensional signals to demonstrate the function of time. Furthermore, this waveform display allows users to focus upon core elements of the signals, amongst them being the amplitude, rise time, frequency, distortion, time interval and many more. But what are the best oscilloscope brands? Let us check them out right now!

1. GOS-620

We will open this article by discussing the GOS-620 oscilloscope, a product that has been developed by GW Instek. This item contains two scope channels, as well as having a bandwidth of 20MHz. The GOS-620 also has a calculated rise time of 17.5ns, as well as having a CRT scope display. The item contains what is known as an OSC GOS-620 One 20MHz GTP-020A-4 Passive Probe for each of its two scope channels. Now, the product doesn’t have an SHVC, but the oscilloscope is compliant with RoHS regulations. The only downside is that, as this is an older item, availability is somewhat scarce right now, but you can still find out how to get your hands on the GOS-620 oscilloscope by getting in touch with OEM Secrets today.

2. GOS-6103

It’s understandable that you may wish to keep your options when it comes to finding the best oscilloscope possible for your business. With that in mind, then, let us now shine the spotlight on the GOS-6103, an oscilloscope that also comes courtesy of GW Instek. This product also has two scope channels, but the crucial point is that it has a far greater bandwidth of 100MHz. Now, it does have a lower calculated rise time of 3ns, though it also has a CRT scope display. Note that this has a US plug type, which is worth bearing in mind prior to using the oscilloscope. It has an input impedance of 1Mohm, though it hasn’t been officially tested for RoHS regulations. And should you get your hands on the GOS-6103, the typical price comes in at around £147.00.

3. 2120C

In case you still wish to look elsewhere, though, then we want to give a special mention to the 2120C oscilloscope. This product has been developed by B&K Precision, and once again it contains two scope channels. As with the GOS-620, the 2120C oscilloscope has a maximum bandwidth of 30MHz. Again, the calculated rise time comes in at approximately 12ns, and once more, the item has a CRT scope display. Meanwhile, there is one PR.33A probe for each of the two scope channels that this product boasts. Unlike the GOS-6103, the 2120C has been tested for RoHS compliance and thus passes all health and safety measures. Last but not least, the 2120C is available from OEM Secrets right now courtesy of our distributors, with the lowest price being £483.33 when buying this oscilloscope via Arrow Electronics.

4. 2121C

Another example of a high-performance oscilloscope is the 2121C, and this also comes from B&K Precision. It’s worth noting, though, that it does share a lot of similar traits with the aforementioned 2120C. For instance, the 2121C has two scope channels, it has a maximum bandwidth of 30MHz, and its calculated rise time comes in at 12ns. The CRT scope display type comes into play again, and again there is one PR.33A probe apiece for all of the two scope channels. This is an RoHS compliant product as well. And because it is newer and performs to a higher standard, it’s understandable that the price increases accordingly, with this being purchasable from OEM Secrets today at £528.90 when making a buy via Allied Electronics & Automation.

5. 2160C

To close out this article, we are going to shine the spotlight on the 2160C, and this is one more oscilloscope that comes courtesy of B&K Precision. As with all of the examples listed here, there are two scope channels, but it’s worth noting that the 2160C has a maximum bandwidth of 60MHz. Not unlike the other oscilloscopes featured here, the calculated rise time is 12ns and there is a CRT scope display type. There is a PR.33A probe for each of the two scope channels, and it ticks the box of being RoHS compliance as well. Now, the price points for the 2160C vary greatly, but the best option right now is to buy £64.96 when buying it via Newark Electronics from our range of stock here at OEM Secrets.

Active and passive components are an integral part of electronic gadgets. Passive components are those elements that store the energy and later release it in an electric or magnetic field. They have the potential to organise a robust relationship between voltage and current. Resistors, capacitors, coil, inductors, resonators, terminals, connectors, cables, switches, circuit protection devices and printed circuit boards (PCB) are typical examples of passive components. There are two types of passive elements: Lossy or Dissipative and lossless elements.

 There are many advantages of passive elements, such as they require no extra energy and amplifying resources. They are sturdy, reliable and easy to manage. But there are certain wrong notions too affiliated with passive elements. Here are a few misconceptions linked with passive components:

 ●       Passive components need an energy source

 A misconceived notion about passive components requires additional energy sources like active components, but it is a false concept. Passive elements utilise the stored energy for running operations and need no extra energy to formulate their operational mechanism. Passive elements can run their devices with utmost care and precision without needing a specific voltage.

 ●       Passive components generate energy.

 Passive components such as capacitors, transformers and resistors do not create energy. Only active elements accomplish the role of generating energy. They only catch the energy and store it in their functional realm. Passive element stocks power as a current. For example, a capacitor stores power in the electric field configuration, whereas an inductor reserves as a magnetic field.

●       They have Non- linear characteristics.

 In electronic elements, linear devices refer to aspects as a straight line from the basis. The change in linear elements has voltage directly proportional to the modification in current. Non-linear devices are the ones whose difference in voltage is not directly proportional to the modification in current. Generally, it is conceived that passive components have non-linear characteristics, whereas they have only linear traits. Passive elements lay in linear category only and perform the role of energy acceptors.

 ●       Passive components require an external source.

 Passive components have the specialty to regulate all operations without external sources. They do not require any external source or connection to execute their systems.

 ●       They can control the current in devices.

 Often, it is stated that both active and passive elements can control the current in the devices. But, only active elements can regulate the current in equipment and not passive elements.

 ●       Passive components gain power.

 Passive components do not have the proficiency to gain power or amplify it. Their mechanisms support energy storage in various forms but restrict any amplification criteria.

 Why us?

Electronic components are fundamental discrete gadgets in any electronic framework to use in electronics in any case extraordinary related fields. These components are fundamental components that are utilized to plan electrical and electronic circuits. These components have at least two terminals which are utilized to interface with the circuit. The arrangement of electronic components should be possible dependent on applications like dynamic, aloof, and electromechanical.

In planning an electronic circuit following are mulled over:

Fundamental electronic components: capacitors, resistors, diodes, semiconductors, and so on.

Power sources: Signal generators and DC power supplies.

Estimation and examination instruments: Cathode Ray Oscilloscope (CRO),  multimeters, and so forth.

Classification of Electronic Components:

Electronic gadgets are part of our daily life. If you are as old as me, you might remember when you used to wait to use the phone booth to contact your friend after writing them a letter and stating when you could have a chat. Nowadays, you can hardly function if you forgot your phone rushing to catch that train as we are always tethered to them 24 hours 7days a week.

Anyway, back to electronic components. They are classified into two groups namely:

1. Active components: Active components supply current or energy in an electronic circuit and examples of these can be generators, alternators, diodes, transistor, voltage, MOSFET, Logic gates, and current sources.

What are active components?

Other examples of active components like amplifiers, vacuum tubes, and transistors will help us understand these basic electronic components.
