Pros & Cons
OWON HDS2202S
Pros
- 200MHz bandwidth in a handheld form factor — genuinely impressive
- Built-in multimeter and function generator in the same device
- Battery powered — actual field-ready portability
- Protocol decoding for SPI, I2C, and UART out of the box
- Deep memory for a handheld — exceptional for field capture work
Cons
- 3.5-inch screen is uncomfortably small for complex waveform analysis
- Only 2 channels — limits simultaneous signal debugging
- Button interface can feel clunky after using a touchscreen scope
- Around $309, you're close to proven benchtop scope territory — consider your priorities
- OWON's documentation is sparser than Rigol or Siglent
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 is an impressive piece of kit for field and portable work — 200MHz bandwidth, protocol decoding, a built-in multimeter and function generator, and battery power in a package that fits in a jacket pocket. Around $309, you still need to be honest with yourself about how you'll use it. A little more budget buys you a Rigol DS1054Z with 4 channels and a 7-inch display for bench work. The HDS2202S makes sense if portability is a genuine requirement — automotive diagnostics, field service, under-the-hood debugging — rather than just bench work in a small space. For primary bench use near this price, a benchtop scope is the better tool.
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.
