FAQs
What should I look for in an oscilloscope?
Before you buy oscilloscopes, consider the following points:
- Scope application: Do you need a benchtop device for lab use or a handheld device for the field?
- Signal measurement: How many signals do you want to measure at a given time?
- Amplitude: What are the maximum and minimum amplitudes and frequencies that you need to measure?
- Sampling: Is your signal sample repetitive or single-shot?
- Frequency: Do you need to view the signal in the frequency domain or time domain?
Also, look for after-sales support, financing options, and calibration certificates when you buy a pre-owned scope.
What should I check after purchasing an old oscilloscope?
Follow these steps to verify the scope's condition:
- Check the device for any anomalies in the body, such as cracks, scratches, dents, and tampered warranty-void stickers.
- Switch on the device to make sure it’s in working condition.
- Verify that all input channels work by using the probes included with the package. You can use the Auto button, rather than adjusting the knobs manually.
- Check the display for broken pixels and whether all the buttons are working properly. You can either do this manually or via the self-testing feature, commonly available in the Utility section.
- Check whether the keyboard works properly and if the encoders are functioning.
- Perform the button backlight check.
With these basic steps, you can confirm whether your scope is in good condition and working properly.
What is the difference between the digital phosphor oscilloscope (DPO) and the mixed-signal oscilloscope (MSO)?
The digital phosphor oscilloscope (DPO) allows you to deliver unique acquisition and display capabilities to accurately reconstruct signals. Its microprocessor works in parallel with the integrated acquisition system, so the scope's acquisition speed remains unaffected. Use the DPO for communication mask tests, advanced analyses, digital debugging of intermittent signals, and designing and troubleshooting various applications.
The mixed-signal oscilloscope (MSO) combines the functionality of a DPO with that of a 16-channel logic analyzer. Because they can analyze both analog and digital signal representations, MSOs can perform root cause analysis of digital problems faster. Use MSOs to debug digital circuits with their capabilities, such as high-res acquisition, powerful digital triggering, and analysis.
Our refurbished equipment undergoes the same quality checks as new equipment, as well as a 16-point certification process in an ISO 9001/A2LA/17025/Z540 laboratory. You also get a calibration certificate, warranty, and technical support.
