UNI-T MSO5000HD Series vs Rohde & Schwarz RTA4000 Series
True 12-bit resolution, far deeper memory and a much faster capture rate than the 10-bit RTA4000 — the R&S draw is its brand and calibration network.
The UNI-T MSO5000HD is a true 12-bit HD oscilloscope family; the Rohde & Schwarz RTA4000 is a 10-bit family. Both reach 1 GHz at 5 GSa/s and share a 10.1-inch 1280×800 touchscreen. The MSO5000HD adds 12-bit resolution, far deeper memory (500 Mpts vs 100 Mpts/ch) and a much higher capture rate, with a 5-year warranty; Rohde & Schwarz's draw is its metrology pedigree and global calibration network. Match the two by bandwidth below.
The MSO5000HD runs a native 12-bit front end with 500 Mpts; the 10-bit RTA4000 carries 100 Mpts/ch. Both reach 1 GHz at 5 GSa/s. UNI-T leads on resolution, memory and capture rate; R&S on brand and calibration.
Match the models by bandwidth
| Bandwidth | Channels | UNI-T model | Rohde & Schwarz |
|---|---|---|---|
| 350 MHz | 4+16 | UNI-T MSO5034HD | RTA4004 (to 350 MHz) |
| 500 MHz | 4+16 | UNI-T MSO5054HD | RTA4004 (to 500 MHz) |
| 1 GHz | 4+16 | UNI-T MSO5104HD · Compare › | RTA4004 (to 1 GHz) |
The RTA4000 is a 10-bit family (one 4-ch model, bandwidth licenses to 1 GHz, 100 Mpts/ch); the MSO5000HD is 12-bit (500 Mpts). R&S US pricing is quote-based — figure is an estimated configured price; verify before launch.

True 12-bit, not 10-bit
A native 12-bit front end resolves 4× the vertical detail of the RTA4000's 10-bit ADC.
Far deeper memory, faster capture
500 Mpts versus 100 Mpts/ch, and up to 800,000 wfms/s versus the RTA4000's >64,000.
Flagship platform, five-year warranty
1 GHz, 5 GSa/s, 15-protocol decode and optional power/timing analysis, with US support and 3+2 (5-year) coverage.
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 R&S RTA4000?
On specifications and price, yes: the MSO5000HD is a true 12-bit family with far deeper memory and a much higher capture rate than the 10-bit RTA4000, at a fraction of the configured price. Rohde & Schwarz offers a long metrology pedigree and a worldwide calibration network.
Is the RTA4000 really 10-bit and the MSO5000HD 12-bit?
Yes. The RTA4000 uses a 10-bit ADC; the MSO5000HD is native 12-bit (16-bit with enhanced resolution) — the core reason to choose an HD scope.
What does Rohde & Schwarz offer that UNI-T does not?
A long metrology track record, premium build and a global service/calibration network. Those can justify the premium for some labs; otherwise the MSO5000HD delivers more capability for far less.
What warranty and support come with UNI-T HD scopes?
Exclusive 3+2 Coverage — 3 years standard plus 2 more with free product registration, 5 years total — with US-based support, US stock, free Continental-US shipping and a 30-day return window.
