Pros & Cons
Rigol DHO924S
Pros
- 250MHz bandwidth with 4 channels for under $500 — exceptional value
- 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
Siglent SDS1204X-E
Pros
- 200MHz bandwidth with 4 channels — strong spec combination
- CAN and LIN decoding included at no extra cost
- 14Mpt memory depth for long serial transaction captures
- Proven, reliable platform with a solid firmware update history
- Good long-term track record from Siglent
Cons
- At ~$775, the DHO924S offers 250MHz and a touchscreen for $326 less
- 7-inch non-touch display feels dated compared to modern alternatives
- No function generator
- Hard to justify the $356 premium over the SDS1104X-U at $419
Our Verdicts
Rigol DHO924S
The Rigol DHO924S is the best hobbyist oscilloscope under $500 in 2026, and I say that having used the DS1054Z for years before switching. The 7-inch IPS touchscreen transforms the experience — pinch to zoom, tap to place cursors, swipe to scroll through captures — in a way that button-based scopes simply can't match. Add 250MHz bandwidth, 4 channels, 50Mpt memory, a function generator, WiFi, and CAN/LIN protocol decoding at $449, and it obsoletes the DS1054Z in every spec column except community documentation and proven long-term reliability. If you're buying a scope in 2026 and can spend $449, this is the one to get. The only reasons to look elsewhere: you need deeper memory (Siglent SDS2104X Plus), you want proven track record over specs (DS1054Z), or you need CAN/LIN included free and can save $30 (Siglent SDS1104X-U at $419).
Siglent SDS1204X-E
The Siglent SDS1204X-E is a solid, proven instrument — but at ~$775, it's a genuinely hard sell in 2026. The 200MHz bandwidth with 4 channels and free CAN/LIN decoding is still a good spec combination, and Siglent's reliability and firmware update track record are real advantages. The problem is the competition. The Rigol DHO924S at $449 gives you 250MHz and a touchscreen for $326 less. The Siglent SDS1104X-U at $419 gives you 4 channels with CAN/LIN decoding for $356 less (at 100MHz). To justify the SDS1204X-E today, you'd need to specifically need 200MHz bandwidth, 4 channels, and CAN/LIN — and be unwilling to use either of those alternatives. That's a narrow use case at this price.
