Pros & Cons
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
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
Our Verdicts
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.
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.
