Pros & Cons
Siglent SDS1104X-U
Pros
- 4 channels with 100MHz bandwidth — best of both in Siglent's lineup
- CAN and LIN decoding included — no license fees unlike Rigol
- 14Mpt memory depth for long capture sessions
- Better probe compensation and input specs than older Siglent models
- Siglent's firmware has matured significantly with recent updates
Cons
- ~$419 for a 100MHz, non-touchscreen scope is a stiff ask
- No touchscreen — button navigation only
- 1GSa/s sample rate is adequate but not exceptional
- Rigol DHO924S offers 250MHz and a touchscreen for $30 more
Siglent SDS1202X-E
Pros
- 200MHz bandwidth — 4x the stock DS1054Z at nearly the same price
- 14Mpt memory depth is excellent for capturing long waveforms
- Protocol decoding includes CAN and LIN — Rigol charges extra for these
- SPL (Siglent Programming Language) for scripting and automation
- Serial decode is free, not locked behind a paid license
Cons
- Only 2 channels — the fundamental tradeoff versus the DS1054Z
- Interface is less intuitive than Rigol's — steeper learning curve
- Smaller community means fewer tutorials and answered questions online
- No touchscreen — button-heavy navigation
- No function generator
Our Verdicts
Siglent SDS1104X-U
The Siglent SDS1104X-U is Siglent's answer to the 4-channel mid-range market, and its CAN/LIN decoding is its killer differentiator. Rigol charges extra for CAN decoding on most models; Siglent includes it free. If you're doing automotive embedded work — car CAN bus debugging, LIN network analysis, anything that touches vehicle electronics — the SDS1104X-U at $419 is the most cost-effective path to proper protocol support. For general hobbyist use without automotive protocol requirements, the DS1054Z at $349 remains better value, and the Rigol DHO924S at $449 offers 250MHz bandwidth and a touchscreen for just $30 more. I'd buy the SDS1104X-U specifically if CAN/LIN decoding is non-negotiable.
Siglent SDS1202X-E
The Siglent SDS1202X-E is the DS1054Z's biggest competitor, and it wins on raw specs: 200MHz bandwidth, 14Mpt memory, and protocol decoding that includes CAN and LIN without paying for licenses. The catch is you only get 2 channels, and that trade-off matters more than it sounds. When you're debugging SPI with clock, data, and chip-select lines all running, or trying to correlate an analog signal with a digital trigger, you'll wish you had 4 channels. If you work primarily with audio circuits, RF signals, or single-channel measurements, the 200MHz bandwidth is genuinely useful and this scope makes complete sense. For general embedded debugging with multiple signals, I'd take the DS1054Z's 4 channels over the extra bandwidth.
