Pros & Cons
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
Rigol DHO802
Pros
- 12-bit ADC at $329 — the cheapest way to get modern 12-bit resolution from a major brand
- Same compact form factor and touchscreen as the rest of the DHO800 series
- 25Mpt memory depth is excellent for a scope at this price
- USB-C power means you can run it from a portable battery pack
- Protocol decoding for SPI, I2C, UART, and CAN included
- Modern Rigol UI — the same intuitive touchscreen experience as the DHO924S
Cons
- Only 2 channels — the biggest limitation for embedded debugging
- 70MHz bandwidth is adequate but not exciting
- Fan noise carries over from the DHO800 series
- For ~$120 more, the DHO804 adds 2 more channels which matters enormously
- No function generator
Our Verdicts
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.
Rigol DHO802
The Rigol DHO802 is the budget entry point to 12-bit oscilloscope territory, and at $329 it's genuinely compelling. You get the same modern touchscreen interface, 12-bit ADC, and compact form factor as the rest of the DHO800 series, just with 2 channels instead of 4. The 25Mpt memory and protocol decoding are both strong at this price. The honest question is whether 2 channels are enough for your work — if you're probing a single signal or doing basic Arduino debugging, absolutely. The moment you need to correlate clock and data lines on SPI, or monitor multiple signals simultaneously, you'll wish you had 4 channels. The DHO804 at ~$439 adds those extra channels, and for most users that $110 premium is worth paying upfront rather than regretting later.
