As you can see, the Velleman DVM856 is a more affordable option than the Rigol DS1054Z and the Saleae Logic 8. However, it also has fewer channels and a lower sampling rate. If you need a more powerful oscilloscope with more channels and a higher sampling rate, then the Rigol DS1054Z or the Saleae Logic 8 would be a better choice. However, if you are on a budget and only need a basic oscilloscope, then the Velleman DVM856 is a good option.

Here is a more detailed comparison of the three oscilloscopes:

Velleman DVM856

• Pros: Affordable, easy to use, good display
• Cons: Few channels, low sampling rate

Rigol DS1054Z

• Pros: More channels, higher sampling rate, more features
• Cons: More expensive, not as easy to use as the Velleman DVM856

Saleae Logic 8

• Pros: Same features as the Rigol DS1054Z, but with more channels
• Cons: More expensive than the Rigol DS1054Z

Ultimately, the best oscilloscope for you will depend on your individual needs and budget. If you are on a budget and only need a basic oscilloscope, then the Velleman DVM856 is a good option. However, if you need a more powerful oscilloscope with more channels and a higher sampling rate, then the Rigol DS1054Z or the Saleae Logic 8 would be a better choice.
