Pros & Cons
Digilent Analog Discovery 3
Pros
- 14 instruments in one: scope, logic analyzer, protocol analyzer, function gen, power supplies, network analyzer, and more
- WaveForms software is excellent, free, and regularly updated
- 16-channel logic analyzer is invaluable for digital protocol debugging
- Fits in a pocket — genuinely portable full lab capability
- Great for students and educators who need multiple instrument types
Cons
- Only 125MSa/s — significantly lower than benchtop scopes
- Requires a PC to operate — no standalone use in the field
- 2 analog channels with limited bandwidth compared to benchtop alternatives
- 32Kpt analog memory depth is very shallow for longer captures
- Not a replacement for a dedicated scope when analog performance matters
OWON HDS2202S
Pros
- Two oscilloscope channels with 200MHz bandwidth
- 1GSa/s maximum sample rate
- Built-in digital multimeter
- Built-in waveform generator
- Manufacturer-stated battery runtime of 3–6 hours
Cons
- 8 Kpts memory limits long waveform captures
- Only 2 oscilloscope channels
- Only Edge triggering is documented for this model
- No documented serial-protocol decoding
- 3.5-inch display is smaller than typical benchtop displays
Our Verdicts
Digilent Analog Discovery 3
The Digilent Analog Discovery 3 isn't really an oscilloscope — it's a multi-instrument lab that happens to include a 2-channel oscilloscope alongside 13 other tools. The 16-channel logic analyzer is its killer feature for embedded work: you can monitor SPI, I2C, GPIO pins, and PWM outputs simultaneously, something a 4-channel scope simply cannot do. WaveForms software is genuinely excellent — one of the best oscilloscope software experiences on any platform. As a pure oscilloscope, the 125MSa/s sample rate and 32Kpt memory are real limitations that you'll notice on any non-trivial analog signal. This is the right tool if you need a logic analyzer AND a scope AND a function generator and can only buy one device — especially for embedded development and student labs. If you primarily need to measure analog signals or capture long waveforms, a dedicated benchtop scope will serve you better.
OWON HDS2202S
The OWON HDS2202S combines two 200MHz oscilloscope channels, a 1GSa/s maximum sample rate, a digital multimeter, and a waveform generator in a handheld instrument. OWON states a 3–6-hour battery runtime. Its documented 8 Kpts memory and Edge trigger make it most appropriate for portable signal checks rather than deep captures or serial-bus analysis.
