3. Rigol DS1054Z
The Rigol DS1054Z has become a popular oscilloscope for hobbyists due to its excellent value and hackability. While it’s advertised as a 50 MHz oscilloscope, it can often be “unlocked” to 100 MHz with a simple software modification. That makes it an incredible bargain.
Pros:
- ✅ Excellent value for the price.
- ✅ Hackable to unlock higher bandwidth (unofficially).
- ✅ Large community support and available resources.
Cons:
- ❌ Officially only 50 MHz bandwidth (without hacking).
- ❌ Hacking voids warranty (if discovered).
- ❌ Interface isn’t the most modern.
Verdict: A great choice for budget-conscious hobbyists who are comfortable with a little bit of hacking. The potential to unlock higher bandwidth makes it an incredibly attractive option.
4. FNIRSI 1014D
The FNIRSI 1014D is a portable and compact oscilloscope, perfect for hobbyists who need to troubleshoot on the go. It’s small enough to fit in a bag and has a built-in battery. Don’t expect the performance of a benchtop model, but it’s surprisingly capable for its size.
Pros:
- ✅ Very portable and compact.
- ✅ Built-in battery for on-the-go use.
- ✅ Affordable price.
Cons:
- ❌ Limited bandwidth compared to benchtop models.
- ❌ Smaller screen can be harder to read.
- ❌ Build quality feels a bit cheap.
Verdict: Ideal for hobbyists who need a portable oscilloscope for field work or who have limited space. It’s not a replacement for a benchtop model, but it’s a handy tool to have.
5. Seeed Studio DSO Nano v3
The Seeed Studio DSO Nano v3 is an ultra-portable and extremely affordable oscilloscope. It’s about the size of a small MP3 player. It’s mainly for simple signal viewing and basic troubleshooting. It is a good starting point if you are new to oscilloscopes.
Pros:
- ✅ Extremely affordable.
- ✅ Ultra-portable and pocket-sized.
- ✅ Easy to use for basic signal viewing.
Cons:
- ❌ Very limited bandwidth and functionality.
- ❌ Tiny screen.
- ❌ Not suitable for complex projects.
Verdict: A good option for absolute beginners who want to experiment with oscilloscopes without spending a lot of money. It’s also useful for quick signal checks when portability is paramount. It’s more of a learning tool than a serious piece of test equipment.
Buying Guide
Choosing the right oscilloscope can feel overwhelming, but here’s what to keep in mind:
- Bandwidth: This is the most important specification. It determines the maximum frequency of signals the oscilloscope can accurately measure. As a general rule, choose an oscilloscope with a bandwidth at least 5 times higher than the highest frequency signal you plan to measure. For general hobby use, 50-100 MHz is usually sufficient.
- Channels: The number of channels determines how many signals you can view simultaneously. Two channels are usually enough for basic projects, but four channels can be helpful for more complex circuits.
- Sample Rate: The sample rate determines how often the oscilloscope takes a measurement of the input signal. A higher sample rate results in a more accurate representation of the signal.
- Memory Depth: This determines how much data the oscilloscope can store. A deeper memory allows you to capture longer periods of time without losing detail.
- Features: Some oscilloscopes come with extra features like built-in signal generators, logic analyzers, and spectrum analyzers. These features can be helpful, but they also increase the price. Consider which features are most important for your projects.
- Portability: Do you need a portable oscilloscope for field work, or will you primarily use it on your workbench? Portable oscilloscopes are smaller and lighter, but they typically have lower performance than benchtop models.
- Budget: Oscilloscopes range in price from a few hundred dollars to several thousand dollars. Set a budget before you start shopping and stick to it.
FAQs
Q: What is bandwidth, and why is it important?
A: Bandwidth is the range of frequencies an oscilloscope can accurately measure. It’s important because if you try to measure a signal with a frequency higher than the oscilloscope’s bandwidth, the measurement will be inaccurate.
Q: How many channels do I need?
A: Two channels are usually sufficient for basic projects, but four channels can be helpful for more complex circuits where you need to compare multiple signals simultaneously.
Q: Is a digital oscilloscope better than an analog oscilloscope?
A: Digital oscilloscopes are generally preferred because they offer more features, better accuracy, and the ability to store and analyze data. Analog oscilloscopes are becoming increasingly rare.
Q: Can I use an oscilloscope to troubleshoot audio circuits?
A: Yes, an oscilloscope is a valuable tool for troubleshooting audio circuits. You can use it to visualize waveforms, measure signal levels, and identify distortion.
Q: What accessories do I need for my oscilloscope?
A: At a minimum, you’ll need probes to connect the oscilloscope to your circuit. You may also want to consider a carrying case, a probe calibration source, and various adapters and connectors.
Conclusion
Choosing the best oscilloscope for hobbyist use really depends on your budget, the types of projects you’re working on, and how portable you need it to be. The Siglent SDS1104X-E is a great all-arounder, while the Hantek DSO2D15 offers excellent value. If you need something portable, the FNIRSI 1014D is a good option. No matter which one you choose, an oscilloscope can be a valuable addition to your electronics workbench.
