As an engineer, you know firsthand the importance of signal integrity in your projects. It can mean the difference between accurate and unreliable measurements, successful and failed tests, and the success or failure of your project.
Finding a quality oscilloscope that doesn't sacrifice signal integrity can be challenging. There are many cheap, inaccurate digital oscilloscopes on the market. It can be difficult to tell the difference between these models and ones that offer reliable measurement data.
One of the main drawbacks is that cheap oscilloscopes often have inferior signal integrity, resulting in inaccurate measurements when characterizing digital signals. These inaccuracies lead to wasted time and effort.
A High-quality, calibrated used oscilloscope is the best way to ensure accurate measurements without sacrificing signal integrity. This article will consider why signal integrity is so important, the dangers of buying miscalibrated scopes, and how you can buy a quality used oscilloscope.
Signal integrity is a measure of the quality of an electrical signal. It is a critical factor in the design of electronic systems and components, particularly high-speed digital devices. Different specifications of an oscilloscope, when combined, make up signal integrity.
But how do you know what these specifications are? Some of the most important specs to consider include the following:
|Bandwidth||The bandwidth of an oscilloscope is one of the most important specs to consider when evaluating the integrity of a signal. A scope with a wide bandwidth will be able to capture high and low-frequency signals with greater fidelity than a scope with a narrower bandwidth.|
|Sampling rate||The sampling rate of an oscilloscope determines how often the scope measures the signal. A higher sampling rate will allow higher measurement resolution of high-speed signals but requires more processing power and memory.|
|Rise time||The rise time of an oscilloscope measures the speed at which the scope can transition from low to high voltage levels. A scope with a fast rise time will be able to capture sharp changes in signal level with greater accuracy than a scope with a slower rise time.|
|Signal-to-noise ratio||The signal-to-noise ratio (SNR) is a measure of the quality of the scope's input stage. A higher SNR means less noise in the signal, and the scope will be able to reproduce the shape of the waveform accurately.|
|Jitter||Jitter is a measure of the stability of the timing of the scope's signals. A scope with low jitter will be able to capture repetitive signals with greater fidelity than a scope with high jitter.|
These are just a few specs that need to be kept in mind when evaluating the integrity of a signal. While high-end oscilloscopes tend to have better signal integrity than cheaper models, even expensive units can have poor signal integrity if not calibrated.
One of the biggest dangers of buying a used oscilloscope online is that it has compromised signal integrity. If an oscilloscope has poor signal integrity, it can affect many other factors, including the accuracy of the measurement and the shape of the signal.
This can lead to:
Good design practices and proper testing and calibration will help ensure a used oscilloscope meets its signal integrity requirements.
Many online vendors sell used digital storage oscilloscopes at discounted prices. Many do not calibrate these types of scopes before selling. These vendors cannot guarantee the accuracy of an oscilloscope's measurements or its signal integrity.
It's tempting to want to buy a cheap oscilloscope. But in doing so, there is a significant risk that you will be sacrificing signal integrity, accuracy, and reliability. Even the quality of the device may be poor, having different broken components not working as expected.
With no assurance that you'll get the quality of product and reliability you need, you don't want to take that kind of risk.
The best way to ensure accuracy and signal integrity is to buy a high-quality, calibrated, used oscilloscope from a reputable vendor. This will guarantee that your oscilloscope has the highest quality signal integrity. Reputable vendors will always have the instruments they sell tested and calibrated by experts. They also stand behind their product with warranties and guarantees.

3. Comprehensive cleaning. In-depth cleaning with specific vacuum-based technology. Whatever can't be cleaned is replaced.
4. Update to the latest firmware and software. After verifying its performance, we update the unit to the latest compatible firmware and software (updated operating system software only, not upgraded).
5. Customization process. Hardware options, applications, or software options are added or removed according to customer order.
6. Calibration and safety tests. The unit gets calibrated and safety tested.
7. Original manuals and accessories. The unit receives the same brand-new accessories and manuals as a new Keysight instrument.
8. Final 101-point inspection. Before leaving, each instrument goes through performance verification and a final 101-point quality check.
9. Standard like-new warranty. The factory-refurbished unit receives the same warranty as a new Keysight instrument (varies by model and region).
10. Unit packed and shipped. The instrument and its accessories are carefully packed and shipped to the customer.
As an extra layer of protection, Keysight offers support, service, and upgrade possibilities. That kind of assurance is invaluable and only possible through Keysight.
