Native 12-Bit Performance

Built around UNI-T's R12™ native 12-bit ADC architecture, the MSO1154HD delivers sixteen times the vertical resolution of conventional 8-bit oscilloscopes while maintaining its full 150 MHz bandwidth and maximum sample rate. The increased measurement resolution makes it easier to observe small voltage variations, switching ripple, sensor outputs, and low-level analog signals without relying on software averaging or reduced acquisition performance.

Ultra Phosphor 3.0 Acquisition

Ultra Phosphor 3.0 technology captures up to one million waveforms per second while displaying 256 levels of intensity grading, allowing frequently occurring signals to stand out while rare glitches and intermittent timing faults remain visible. Combined with deep acquisition memory, the system helps engineers identify transient events, protocol errors, and signal integrity problems that can be difficult to detect on slower oscilloscopes.

Deep Memory and Mixed-Signal Debugging

With 100 Mpts of acquisition memory available on each analog channel, the MSO1154HD captures long signal records without sacrificing sample resolution. Engineers can analyze extended startup sequences, communication transactions, and complex embedded events while maintaining detailed waveform visibility. An optional UT-M26 logic probe adds 16 synchronized digital channels, allowing analog and digital signals to be viewed together for efficient mixed-signal debugging.

Protocol Decoding and Power Analysis

The MSO1154HD includes one of the most comprehensive protocol decoding packages in its class, with standard support for UART, RS-232, RS-422, RS-485, I²C, SPI, CAN, CAN-FD, LIN, and Audio communication buses. Built-in power analysis measures efficiency, ripple, switching loss, and other key power-quality parameters, making the oscilloscope well suited for embedded systems, industrial controls, automotive electronics, and power supply development.

Spectrum Analysis and Automated Measurements

An integrated FFT spectrum analyzer with up to 1 Mpts resolution enables engineers to investigate harmonics, switching frequencies, EMI sources, and clock signals without requiring a separate instrument. Fifty-six automated measurements, statistical analysis, trend displays, and pass/fail mask testing simplify waveform characterization, production testing, and long-term performance evaluation.

Designed for Modern Engineering Labs

A responsive 7-inch capacitive touchscreen with gesture navigation provides intuitive control of waveforms and measurements, while USB, LAN, HDMI, and AUX interfaces simplify data transfer, remote operation, and classroom demonstrations. Whether used in an engineering laboratory, university teaching environment, or electronics development bench, the MSO1154HD delivers professional measurement capability in an easy-to-use platform.

Applications

The UNI-T MSO1154HD is ideal for embedded systems development, mixed-signal debugging, power electronics design, industrial automation, automotive electronics, sensor evaluation, university laboratories, technical education, and electronics repair. Its native 12-bit architecture, deep memory, integrated protocol decoding, and optional logic analysis provide engineers and educators with a versatile platform for analyzing today's increasingly complex electronic systems.

FAQ's

What protocols are included with the MSO1154HD?

RS-232/UART, I²C, SPI, RS-422, RS-485, CAN, CAN-FD, LIN, and Audio decoding are included standard at no additional cost. All supported protocols are available out of the box — no optional licenses required.

What is the advantage of native 12-bit resolution?

A 12-bit ADC provides 4,096 vertical levels compared to 256 for an 8-bit scope — sixteen times greater detail. This reveals small signals riding on large ones, reduces quantization noise, and improves measurement accuracy on low-amplitude signals like power-supply ripple, sensor outputs, and precision analog circuits. R12™ holds the 12-bit resolution at the full bandwidth and sample rate, with no ERES averaging or sample-rate trade-off.

Can I add digital channels for mixed-signal debugging?

Yes. The UT-M26 logic probe pod adds 16 digital channels for time-correlated analog and digital views.

Does this model include a signal generator?

No. For an integrated 1-channel 25 MHz AWG with Bode plot analysis, see the MSO1154HD-S.

How does the MSO1154HD compare to the higher-bandwidth UPO2000HD or MSO3000HD scopes?

The MSO1000HD platform shares the same R12™ 12-bit ADC architecture, Ultra Phosphor 3.0 acquisition, and standard-included protocol decoding as the UPO2000HD and MSO3000HD families. The differences are bandwidth (150–250 MHz here vs 100–500 MHz on UPO2000HD and 350–1000 MHz on MSO3000HD), capture rate (1,000,000 wfms/s here vs 1,500,000 wfms/s on MSO3000HD), and the front-panel form factor. For embedded prototyping and mid-tier power-electronics work, the MSO1000HD platform delivers the same architectural advantages at a lower price point.

Is the firmware field-upgradable?

Yes. Firmware updates are free over the product's lifetime and install via USB drive or LAN transfer. Optional license unlocks (such as the LA16 logic-analyzer license, when ordered with the UT-M26 pod) have no expiration.
