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
Siglent SDS804X HD
Pros
- 12-bit ADC with what Reddit considers a cleaner analog front-end than Rigol — LeCroy heritage shows
- 2GSa/s sample rate is genuinely faster than the DHO804's 1.25GSa/s
- 50Mpt memory depth matches the DHO924S and doubles the DHO804
- CAN and LIN decoding included free — Siglent's standard generosity on protocols
- 70MHz bandwidth is unlockable to 200MHz via software license — massive upgrade path
- 7-inch capacitive touchscreen with responsive multi-touch gestures
Cons
- 70MHz stock bandwidth is limiting — you're paying for the upgrade path, not the base spec
- No built-in function generator (optional add-on)
- Siglent's community is smaller than Rigol's — fewer tutorials and forum answers
- The DHO804 is the closest Rigol rival near this price
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.
Siglent SDS804X HD
The Siglent SDS804X HD is THE competitor to the Rigol DHO804 that Reddit can't stop debating. On paper, 70MHz around $461 looks underwhelming — but the real story is Siglent's 12-bit ADC implementation, which the community consistently praises as having a cleaner noise floor than Rigol's, thanks to Siglent's LeCroy heritage in analog front-end design. The 2GSa/s sample rate and 50Mpt memory depth are both better than the DHO804. The bandwidth unlock to 200MHz via software license is the ace up its sleeve — it turns a mid-$400s scope into a legitimate 200MHz instrument for an additional fee. If you value measurement quality over Rigol's UI, this is the 12-bit scope to buy. If you want the simplest modern first scope, compare it directly against the DHO804.
