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 DHO804
Pros
- 7-inch IPS touchscreen — same display as the DHO924S
- 25Mpt memory depth is solid for extended capture sessions
- Modern, intuitive interface makes learning easy
- 4 channels with protocol decoding (SPI, I2C, UART)
- WiFi connectivity for remote viewing and data export
Cons
- 70MHz bandwidth is the real compromise — limits this scope's ceiling
- No built-in function generator unlike the DHO924S
- 25Mpts memory is half the DHO924S's 50Mpts
- Stepping up to the DHO924S now costs substantially more
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 DHO804
The Rigol DHO804 is the entry point to Rigol's DHO platform, offering the same 7-inch IPS touchscreen experience as the DHO924S with 70MHz bandwidth and 25Mpt memory at $439. For Arduino, basic analog work, and learning, 70MHz is genuinely sufficient — most signals you'll encounter stay well under this limit. The old objection was that the DHO924S cost almost the same; that is no longer true. With the DHO924S now priced like a premium scope, the DHO804 is the modern Rigol touchscreen pick for buyers who want a current interface without jumping near $900.
