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 DHO924S
Pros
- 250MHz bandwidth with 4 channels and a modern touchscreen workflow
- 7-inch IPS touchscreen with 1024x600 resolution — sharp and responsive
- 50Mpt memory depth for extended captures
- Built-in function generator and WiFi connectivity included
- Modern phone-like interface has almost no learning curve
- Protocol decoding for SPI, I2C, UART, CAN, and LIN
Cons
- 1.25GSa/s sample rate could be higher given the 250MHz bandwidth
- Newer platform means less community documentation than the DS1054Z
- Some early firmware bugs have been reported — check version before updating
- Fan can be audible in a quiet room
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 DHO924S
The Rigol DHO924S is no longer the default hobbyist oscilloscope recommendation now that Amazon pricing is around $899. The 7-inch IPS touchscreen is still excellent — pinch to zoom, tap to place cursors, swipe to scroll through captures — and the spec stack is serious: 250MHz bandwidth, 4 channels, 50Mpt memory, a function generator, WiFi, and CAN/LIN protocol decoding. But at this price it belongs in the premium-upgrade tier, not the beginner tier. Buy it if you need the bandwidth, mixed-signal-ready feature set, and modern Rigol workflow. Most first-time buyers should start with the DS1054Z or DHO804 instead.
