UNI-T MSO3000HD Series vs InfiniiVision 3000T X-Series
12-bit resolution and far deeper memory on top of the 8-bit 3000T X-Series — Keysight leads on update rate and brand.
The UNI-T MSO3000HD is a true 12-bit HD oscilloscope family; the Keysight InfiniiVision 3000T X-Series is 8-bit. The MSO3000HD adds 12-bit resolution and far deeper memory (500 Mpts vs 4 Mpts) with a larger 10.1-inch display and standard decode, at a fraction of the price; Keysight leads on its 5 GSa/s sample rate, industry-leading 1,000,000 wfms/s update rate, zone-touch trigger and metrology brand. Match the two by bandwidth below.
The MSO3000HD is native 12-bit with 500 Mpts; the 3000T X-Series is 8-bit with 4 Mpts but a very high update rate and zone trigger. UNI-T leads on resolution, memory and price; Keysight on update rate and brand.

12-bit, not 8-bit
A native 12-bit front end resolves 16× the vertical detail of the 3000T's 8-bit ADC — small signals and ripple it averages away.
125x the memory
500 Mpts versus 4 Mpts holds vastly longer records at full sample rate.
More instrument for far less
A larger display, standard decode and a 9-in-1 platform with a 5-year warranty, at roughly a quarter of the price.
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 Keysight 3000T X-Series?
It is a strong 12-bit alternative to the 8-bit 3000T: same bandwidth and channels, with 12-bit resolution, far deeper memory, a larger display and standard decode for far less. Keysight leads on its 1,000,000 wfms/s update rate, zone trigger and metrology pedigree.
Is the 3000T X-Series really 8-bit?
Yes. The InfiniiVision 3000T X-Series uses an 8-bit ADC with optional high-resolution averaging; the MSO3000HD is native 12-bit (16-bit with ERES).
What does Keysight do better?
A 5 GSa/s sample rate, an industry-leading 1,000,000 wfms/s update rate, the zone-touch trigger and a long metrology pedigree. If those lead your decision, the 3000T earns its 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.
