UNI-T MSO5000HD Series vs Siglent SDS3000X HD Series
Two 12-bit HD families — the MSO5000HD leads on sample rate, memory and capture rate; Siglent leads on standard decode.
The UNI-T MSO5000HD and Siglent SDS3000X HD are both 12-bit HD oscilloscope families reaching 1 GHz. The MSO5000HD leads on sample rate (5 vs 4 GSa/s), memory (500 vs 400 Mpts), capture rate and warranty; the SDS3000X HD includes CAN-FD and FlexRay decode as standard where ours are options. Both front ends are quiet 12-bit designs — ours is 75 µVrms at the full 1 GHz. Match the two by bandwidth below.
Both are 12-bit (16-bit ERES), 4-channel HD families with 10.1-inch touch UIs. The MSO5000HD leads on sample rate, memory and capture rate; Siglent leads on standard decode breadth.
Match the models by bandwidth
| Bandwidth | Channels | UNI-T model | Siglent |
|---|---|---|---|
| 350 MHz | 4+16 | UNI-T MSO5034HD | SDS3034X HD |
| 500 MHz | 4+16 | UNI-T MSO5054HD · Compare › | SDS3054X HD |
| 1 GHz | 4+16 | UNI-T MSO5104HD | SDS3104X HD |
SDS3000X HD bandwidths are 350/500 MHz and 1 GHz; the MSO5000HD line matches them. Both are 12-bit with optional 16-channel logic. Prices from authorized US distributors, September 2026.

Faster sampling, deeper memory
5 GSa/s versus 4, and 500 Mpts versus 400 — more time resolution and longer records on the same 12-bit platform.
Higher capture rate
800,000 wfms/s (1.5M sequence) versus 200,000 (890,000 sequence) — a better chance of catching rare events.
Five-year coverage for less
A 5-year warranty and US support at a lower price than the matched SDS3000X HD model.
The bottom line
Every UNI-T HD scope is a 9-in-1 instrument — oscilloscope, 16-channel logic analyzer (option), serial protocol analyzer, spectrum/FFT, frequency counter, 4-digit DVM, Bode-plot analyzer, power analyzer (option) and an optional dual-channel 50 MHz AWG — on a true 12-bit front end with 500 Mpts of memory standard.
Frequently Asked Questions
Is the UNI-T MSO5000HD a real alternative to the Siglent SDS3000X HD?
Yes — both are 12-bit, 4-channel HD families to 1 GHz. The MSO5000HD leads on sample rate, memory, capture rate, warranty and price; Siglent leads on standard CAN-FD/FlexRay decode. Noise floors are level — ours is 75 µVrms at the full 1 GHz, and Siglent does not publish a figure for this model.
How do I match an SDS3000X HD model to a UNI-T MSO5000HD?
By bandwidth: SDS3034X HD → MSO5034HD (350 MHz), SDS3054X HD → MSO5054HD (500 MHz), SDS3104X HD → MSO5104HD (1 GHz).
What does Siglent do better?
Standard CAN-FD and FlexRay decode, where ours are paid options. For automotive-heavy work the SDS3000X HD is a strong alternative; otherwise the MSO5000HD offers a faster sample rate, deeper memory, a higher capture rate and two more years of cover.
Are UNI-T software options subscriptions?
No. Every UNI-T software option — logic, automotive/aerospace decode, power analysis, the AWG — is a permanent one-time unlock. No annual licenses, no renewal fees, no expiring features.
Ready to choose?
Faster sampling, deeper memory and a 5-year warranty on the same 12-bit HD class — matched to the SDS3000X HD by bandwidth.
