AvailabilityOur refurbished oscilloscopes are more readily available than new ones. This is helpful if you need to purchase one quickly or are looking for a specific discontinued model.


How Do I Check the Calibration of My Oscilloscope?

To check the calibration of an oscilloscope, you can follow these steps.

  1. Obtain a calibration signal. You will need a known and stable signal source to calibrate your oscilloscope. You can use a signal generator or a dedicated calibration signal source to generate the test signal.
  2. Connect the calibration signal to the oscilloscope. Connect the output of the calibration signal source to one of the input channels of the oscilloscope. Make sure the signal source is properly grounded.
  3. Adjust the settings on the oscilloscope. Adjust the settings on the oscilloscope to display the calibration signal accurately. This may include adjusting the voltage scale, timebase, and triggering settings.
  4. Compare the displayed signal to the expected signal. Compare the displayed signal on the oscilloscope to the expected signal from the calibration signal source. The displayed signal should match the expected signal as closely as possible.
  5. Make adjustments as necessary. If the displayed signal does not match the expected signal, you may need to adjust the oscilloscope's calibration settings. This may include adjusting the gain, offset, or other calibration parameters. Follow the manufacturer's instructions for making these adjustments.
  6. Document the results. Once the calibration is complete, document the results for future reference. Document the calibration signal source used, the settings on the oscilloscope, and any adjustments.

What Types of Accessories Should I Consider?

After buying your oscilloscope, you may need to invest in some additional accessories. Many accessories can help you get the most out of your oscilloscope, making testing more straightforward and efficient. 

Consider purchasing these items:

  • Probes are essential for connecting the oscilloscope to the device under test. Conventional probes, such as current probes and passive probes, come in different bandwidths, attenuation ratios, and tip styles. Selecting the suitable probe for your application is essential to ensure accurate and reliable measurements.
  • Cables are also required to connect the probes to the oscilloscope. High-quality coaxial cables can minimize signal loss and noise and allow you to make measurements over longer distances.
  • Adapters help convert between different types of connectors, such as BNC, SMA, or N-type, and can allow you to connect your oscilloscope to a broader range of devices.
  • Calibration tools, such as signal generators, reference standards, or calibrators, can help you verify the accuracy and reliability of your oscilloscope measurements.
  • Some oscilloscopes may come with proprietary software that provides additional analysis capabilities or allows you to control the oscilloscope remotely from a computer.

How Do I Properly Maintain and Clean My Oscilloscope?

Investing in an oscilloscope is a big purchase, so keeping your oscilloscope in good working condition is important. Proper maintenance and cleaning of your scope will ensure that it continues providing the accurate and reliable measurements you need.

  1. Regular cleaning. Use a soft cloth or brush to remove dust and debris from the surface of the oscilloscope, and pay special attention to the ventilation openings and cooling fans, ensuring they are not blocked.
  2. Avoid harsh chemicals. Do not use harsh chemicals or solvents, such as acetone or alcohol, to clean the oscilloscope, as they can damage the instrument's plastic parts or screen. Instead, use a mild detergent or a specialized cleaning solution like isopropyl alcohol.
  3. Probe maintenance. Probes are the most commonly used accessories for oscilloscopes, and their proper care is critical to ensure accurate measurements. Check the probes regularly for wear and tear, and clean the probe tips with isopropyl alcohol.
  4. Calibrate regularly. Regular calibration is necessary to ensure accurate measurements. Have your oscilloscope calibrated annually or as recommended by the manufacturer.
  5. Store properly. When not in use, store your oscilloscope in a dry and clean environment, away from direct sunlight, moisture, or excessive heat or cold.
  6. Follow the manufacturer's instructions. Always follow the manufacturer's instructions for maintenance and cleaning, and only attempt to open or repair the oscilloscope if you are qualified to do so.

Why Buy Keysight’s Refurbished Oscilloscopes?

Buying a Keysight Refurbished oscilloscope is a great way to confidently get the scope you need. Why? Because we refurbish our Premium Used Equipment at the same factory that manufactures and tests new products. Your Premium Used oscilloscope must pass the same comprehensive tests and calibration to meet Keysight's quality standards.

Let's look at three further reasons why you should consider buying a Keysight Refurbished oscilloscope.


We understand that not everyone has the budget to buy brand-new equipment. Some top-of-line oscilloscopes can cost hundreds of thousands of dollars, but with Keysight's Premium Used Equipment, you can save up to 90% off the purchase price.

These savings make it a great option for those who need advanced performance but have budget constraints. If you are a hobbyist, student, or professional engineer looking to save on the cost of equipment while still getting top quality and reliability, you will find a great selection at Keysight!

Environmental Impact

Purchasing a refurbished oscilloscope also has ecological benefits. It helps to reduce waste and prevent perfectly usable equipment from ending up in landfills. With about 50 million tons of e-waste produced each year globally, buying a used oscilloscope is a great way to do your part in reducing that number.

It also means that fewer resources are used to manufacture new products, and ultimately, a refurbished oscilloscope will have a smaller carbon footprint than buying a brand-new one. If everyone chooses to buy used instead of new, we could make a real difference in the environment!

Maintenance and Support

When purchasing a refurbished oscilloscope, it's important to consider not only the initial cost but also the long-term value of the device. While buying from other online resellers may seem more cost-effective, it can also come with many uncertainties.

One of those uncertainties is not knowing the condition of the oscilloscope or if it has been properly calibrated. You may also not have access to support or service if you encounter any issues.

That's where Keysight's refurbished equipment comes in. We are the only place where you can get refurbished and officially calibrated oscilloscopes.
