UNI-T MSO3000HD Series vs DHO4000 Series
Two 12-bit HD families — the MSO3000HD ships deeper standard memory and a 5-year warranty; the DHO4000 leads on sample rate and capture rate.
The UNI-T MSO3000HD and Rigol DHO4000 are both 12-bit HD oscilloscope families on 10.1-inch 1280×800 touchscreens. The MSO3000HD (200–500 MHz) ships 500 Mpts of memory standard and an Exclusive 3+2 (5-year) warranty; the DHO4000 (200/400/800 MHz) leads on a 4 GSa/s sample rate and a 1.5M wfms/s UltraAcquire capture rate. Match the two by bandwidth below.
Both run a true 12-bit front end (16-bit with enhanced resolution) with a 10.1-inch capacitive touchscreen. The MSO3000HD adds deeper standard memory and a longer warranty; the DHO4000 leads on raw sample rate and waveform-capture rate.
Match the models by bandwidth
| Bandwidth | Channels | UNI-T model | Rigol |
|---|---|---|---|
| 200 MHz | 4+16 | UNI-T MSO3024HD · Compare › | DHO4204 |
| 350 MHz | 4+16 | UNI-T MSO3034HD | DHO4404 (400 MHz) |
| 500 MHz | 4+16 | UNI-T MSO3054HD | DHO4804 (800 MHz) |
DHO4000 bandwidths are 200/400/800 MHz; the MSO3000HD line is 200/350/500 MHz. Both are 12-bit with optional 16-channel logic. Prices from authorized US distributors, June 2026.

Deeper memory, standard
500 Mpts ships standard versus 250 Mpts on the DHO4000 (500 is a paid Rigol option) — longer records at full sample rate without an upsell.
A wider AWG and 9-in-1 platform
An optional dual-channel 50 MHz AWG (versus Rigol's 25 MHz), plus optional logic, power analysis, spectrum, DVM and Bode plot.
Five-year coverage, US support
Exclusive 3+2 (5-year) warranty and US-based support versus Rigol's 3 years — with one-time software unlocks, never subscriptions.
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 MSO3000HD a real alternative to the Rigol DHO4000?
Yes — both are 12-bit, 4-channel HD scopes with 10.1-inch touchscreens. The MSO3000HD leads on standard memory, AWG bandwidth and warranty; the DHO4000 leads on sample rate (4 GSa/s) and UltraAcquire capture rate. Choose by whether record depth and warranty or raw capture speed matter more.
How do I match a DHO4000 model to a UNI-T MSO3000HD?
By bandwidth: the MSO3024HD (200 MHz) lines up with the DHO4204; the MSO3034HD (350 MHz) sits between the DHO4404 (400 MHz); and the MSO3054HD (500 MHz) sits below the 800 MHz DHO4804.
What do I give up choosing UNI-T over Rigol here?
The DHO4000's honest advantages are a 4 GSa/s sample rate (versus 2.5 GSa/s single-channel) and a higher UltraAcquire waveform-capture rate. If fast single-shot capture dominates your work, weigh those against the MSO3000HD's deeper standard memory and 5-year warranty.
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.
