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
- Touchscreen 12-bit scopes now compete hard at nearby prices
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, it sits close enough to premium touchscreen scopes that the use case needs to be clear
- 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
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, while the DHO804 is the more modern touchscreen alternative near this price. I'd buy the SDS1104X-U specifically if CAN/LIN decoding is non-negotiable.
Siglent SDS1204X-E
The Siglent SDS1204X-E is a solid, proven instrument — but at ~$775, it's a specialized buy 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 competition is clearer now: the SDS1104X-U is much cheaper if 100MHz is enough, the DHO804 is the modern touchscreen pick under $500, and the DHO924S costs more but gives you 250MHz plus Rigol's touchscreen workflow. To justify the SDS1204X-E today, you need to specifically need 200MHz bandwidth, 4 channels, CAN/LIN, and Siglent's platform advantages.
