UNI-T MSO3000HD Series vs WaveSurfer 4000HD Series
Two 12-bit HD families — the MSO3000HD brings far deeper memory and standard decode at a fraction of the price; LeCroy leads on display and analysis software.
The UNI-T MSO3000HD and Teledyne LeCroy WaveSurfer 4000HD are both 12-bit HD oscilloscope families. The MSO3000HD (200–500 MHz) ships 500 Mpts of memory, standard serial decode and a 5-year warranty, for a fraction of the WaveSurfer's price; LeCroy leads on its larger 12.1-inch display, a higher 4-channel sample rate and a deeper analysis software ecosystem. Match the two by bandwidth below.
Both run true 12-bit HD front ends. The MSO3000HD leads on memory depth, standard decode, warranty and price; the WaveSurfer 4000HD leads on display size, 4-channel sample rate and analysis software.
Match the models by bandwidth
| Bandwidth | Channels | UNI-T model | Teledyne LeCroy |
|---|---|---|---|
| 200 MHz | 4+16 | UNI-T MSO3024HD | WS4024HD |
| 350 MHz | 4+16 | UNI-T MSO3034HD | WS4034HD |
| 500 MHz | 4+16 | UNI-T MSO3054HD · Compare › | WS4054HD |
WaveSurfer 4000HD bandwidths run 200 MHz–1 GHz; the MSO3000HD line is 200/350/500 MHz. Both are 12-bit; logic and decode are optional on both. Prices from authorized US distributors, June 2026.

Far deeper memory
500 Mpts versus the WaveSurfer's 12.5 Mpts per channel — tens of times the record length at full sample rate.
Decode and platform, included
Standard UART/I2C/SPI decode on a 9-in-1 instrument, where LeCroy bills serial decode and many functions as paid options.
About a quarter of the price
Matched 12-bit, 500 MHz performance for roughly one-quarter the cost, with a 5-year warranty.
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 LeCroy WaveSurfer 4000HD?
On capability and value, yes: same 12-bit HD class with far deeper memory and standard decode for about a quarter of the price. LeCroy leads on its 12.1-inch display, 4-channel sample rate and analysis software, which can justify the premium for advanced signal-integrity labs.
How do I match a WaveSurfer 4000HD model to a UNI-T MSO3000HD?
By bandwidth: WS4024HD → MSO3024HD (200 MHz), WS4034HD → MSO3034HD (350 MHz), WS4054HD → MSO3054HD (500 MHz).
What does LeCroy do better?
A larger 12.1-inch display, a higher 4-channel sample rate (2.5 vs 1.25 GSa/s) and a mature analysis software ecosystem. For deep signal-integrity work those may justify the premium.
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?
Same 12-bit HD class with far deeper memory and standard decode — for about a quarter of the WaveSurfer's price.
