The MSO3054X is a 500 MHz, four-channel mixed-signal oscilloscope.

With 5 GSa/s real-time sample rate, 500 Mpts of acquisition memory, 16 logic-analyzer channels (with the optional UT-M15 probe pod), and Ultra Phosphor 3.0 waveform mapping at up to 2,000,000 wfms/s in Sequential Mode, the MSO3054X consolidates nine bench instruments into one 10.1-inch capacitive multi-touch footprint — oscilloscope, logic analyzer, AWG, spectrum analyzer, DVM, frequency counter, protocol analyzer, Bode plot, and power analyzer.

For wide-bandwidth power-electronics design, mixed-signal validation across faster MCU and FPGA silicon, switching-converter characterization at the 100s of MHz tier, and small-lab consolidation across multiple instrument categories, the MSO3054X is the top SKU in the MSO3000X line. Calculated rise time falls to ≤0.7 ns — fast enough to resolve the leading edges on wide-bandgap (GaN, SiC) switching devices and the rise-time content of high-speed digital signals where 350 MHz scopes start to round corners. The 12-protocol decode set extends to aerospace serial buses (MIL-STD-1553B, ARINC 429, Manchester) for design-phase work on avionics, defense electronics, and instrumentation systems.

Detailed Features

Nine Instruments in One

The MSO3000X integrates nine instrument functions into one bench unit: digital storage oscilloscope, 16-channel logic analyzer (with the optional UT-M15 probe pod), 50 MHz dual-channel function and arbitrary waveform generator (optional), 1.25 GHz spectrum analyzer (FFT up to 4 Mpts), 4-digit DVM, 7-digit hardware frequency counter, multi-protocol serial-bus analyzer covering 12 bus types, Bode plot analyzer (optional, paired with the AWG for closed-loop sweep), and a six-measurement power-electronics analyzer (optional). For lab benches and small-lab consolidations covering scope, spectrum, protocol decode, AWG-driven stimulus, power analysis, and Bode-plot loop analysis — instruments that would otherwise occupy four to six rack slots and four to six calibration cycles — the integration condenses the bench footprint into one operator surface and one calibration event. For independent test labs validating customer designs across multiple categories, the consolidated nine-instrument view is the operational differentiator.

High-Speed Acquisition — 5 GSa/s, 500 Mpts

The 5 GSa/s real-time sample rate (interleave) and 500 Mpts of acquisition memory hold full waveform fidelity across the 500 MHz analog bandwidth. Standard capture rate runs up to 800,000 wfms/s; in Sequential Mode — the segmented-memory mode that conditions captures on a trigger event — capture rate climbs to 2,000,000 wfms/s, recording up to 200,000 frames for post-capture replay and analysis.

Deep Memory — 500 Mpts Per Acquisition

The 500 Mpts memory depth supports the deepest acquisition windows in the MSO3000X line at full sample rate — capturing tens of thousands of waveforms in a single acquisition for post-event analysis. With Sequential Mode recording up to 200,000 frames, rare-event hunting on high-traffic protocol buses and switching-converter transient capture across long fault-recovery cycles becomes a defined operation rather than a wait-and-watch exercise. For independent test labs validating customer designs, the deep-memory budget makes pass/fail evidence reports comprehensive on the first capture.

Vertical Resolution — 8-Bit Native with ERES to 12-Bit

The MSO3054X uses an 8-bit native ADC with up to 12-bit effective resolution via ERES (enhanced resolution) when bandwidth headroom is available — useful for low-amplitude signal work where quantization noise would obscure detail on switching ripple, sensor outputs, or jitter analysis at the higher-bandwidth tier. For applications requiring native 12-bit resolution at full 500 MHz bandwidth, see UNI-T’s MSO3000HD-series scopes, which use the R12™ native 12-bit ADC architecture for power-electronics ripple-on-bias measurements where the signal-of-interest sits on a high-amplitude DC offset.

Ultra Phosphor 3.0 — 256-Level Grayscale Persistence

Ultra Phosphor 3.0 is UNI-T’s third-generation waveform-mapping architecture: parallel FPGA acquisition with 256-level grayscale intensity grading, a 20 Gbps internal data path, and sub-1 µs dead time. The scope captures fast-edge signals at 2,000,000 events per second in Sequential Mode without missing the rare-event bracket between redraws. Intensity grading shows frequency-of-occurrence directly — frequent waveforms appear brighter, infrequent ones dimmer — making intermittent faults easy to distinguish from normal behavior.

Built-In Spectrum Analyzer — FFT to 4 Mpts

The standard enhanced-FFT spectrum analyzer covers 0 Hz to 1.25 GHz with up to 4 Mpts FFT length, four-channel analysis, four trace types (Normal, Average, Max Hold, Min Hold), and four detection modes. Markers plus a waterfall display track spectral activity over time — for harmonic ID, EMI pre-compliance sweeps, clock-purity verification, and modulated-signal analysis without the cable swap a separate spectrum analyzer requires.

Protocol Analysis — 12 Bus Types Across Five Domains

Twelve protocols across five bus domains: computer serial (RS-232/422/485/UART, I²C, SPI — standard); automotive (CAN, CAN-FD, LIN, FlexRay, SENT — optional); audio (I²S, LJ, RJ, TDM — optional); aerospace (MIL-STD-1553B, ARINC 429 — optional); and Manchester wireless (optional). Triggering and decoding are integrated — trigger on a frame error, identifier match, CRC failure, or missing-ack condition, and the decode displays inline with the captured waveform. The aerospace and Manchester decode set differentiates this protocol envelope from mid-tier scopes that stop at automotive and audio.

50 MHz Dual-Channel AWG with Bode Plot (Optional)

The optional MSO3000X-AWG package adds a 50 MHz dual-channel function/arbitrary waveform generator (16-bit, 250 MSa/s) plus the Bode plot analyzer for frequency-response, loop-stability, filter, and amplifier characterization. Built-in waveforms include sine, square, pulse, ramp, arbitrary, noise, and DC, with AM, FM, ASK, FSK, and sweep modulation. On-screen captures load directly into the AWG for stimulus-response replay.

Power Analysis (Optional) — Six Measurement Types

For wide-bandwidth power-electronics validation on GaN and SiC switching converters, high-frequency motor drives, and full-bandwidth DC-DC characterization, the optional power-analysis package extends the four-channel scope acquisition into a working power analyzer: power quality measurement, harmonic analysis to the 50th order, switching loss across the cycle, ripple analysis on output rails, loop analysis (paired with the Bode plot included with the optional AWG) for closed-loop stability sweeps, and safe operating area visualization for device-stress validation. At 500 MHz of analog bandwidth, the package handles the switching frequencies that wide-bandgap converters and high-speed PoL designs operate at.

Zone Triggering — Rectangle-Drawn Trigger Conditions

Zone triggering isolates an occasional anomaly by trigger condition rather than waveform stability. Draw a rectangle on the display, set Must Intersect or Must Not Intersect, and the scope triggers when the waveform meets the spatial condition. With eleven additional trigger types (edge, pulse width, ramp, runt, over-amplitude, delay, timeout, duration, setup & hold, Nth edge, code pattern), zone triggering turns rare-event hunting into a defined acquisition.

54 Automated Measurements with Histogram and Trend Statistics

54 automated measurement parameters on the analog channels — voltage, time, frequency, statistical, and burst measurements — with up to 27 displayed simultaneously. Statistics include mean, max, min, standard deviation, count, tendency chart, and histogram. The burst function reports values across burst segments — useful for jitter analysis, long-capture characterization, and pass/fail evidence reports.

Fast Fuzzy Autoset

The fuzzy-logic autoset algorithm uses the 7-digit hardware frequency counter and multi-channel parallel processing to lock onto unknown signals quickly: all-channel autoset in under 1.5 seconds, single-channel under 1 second — meaningful on production-line spot-check work and engineering benches that swap test articles often.

10.1-Inch Capacitive Multi-Touch UI

The 10.1-inch 1280×800 HD capacitive multi-touch display supports standard touch gestures (click, slide, zoom, edit, drag) for direct waveform manipulation, plus rectangle-draw for zone triggering. Multi-window layout lets waveform, FFT, decode-list, and measurement-table panels be dragged and resized independently. Knob-and-key controls remain; HDMI output mirrors the display to an external monitor or projector.

Connectivity, SCPI, and WebServer Remote Control

USB 3.0 Host (one front, two rear), USB 3.0 Device, LAN (10/100/1000 BASE-T, VXI-11), HDMI display output, two front-panel Gen Out connectors (paired with the optional AWG), 10 MHz reference In/Out, and AUX Out (Trig Out / Pass-Fail / DVM). Full SCPI command set; the built-in WebServer provides browser-based remote control from PC or mobile without driver installation.

FAQ's

What’s the difference between standard capture rate and Sequential Mode capture rate?

Standard capture rate (800,000 wfms/s) is the rate at which the MSO3054X acquires waveforms during continuous real-time operation. Sequential Mode (2,000,000 wfms/s) uses segmented memory to condition captures on a trigger event, holding up to 200,000 frames of triggered acquisitions for post-capture replay. Use standard mode for general waveform observation; use Sequential Mode for rare-event hunting where the trigger condition is well-defined.

How does the MSO3054X compare to the MSO3000HD-series scopes?

The MSO3054X and the MSO3000HD-series share the same 4-channel mixed-signal platform at 200–500 MHz and the same 9-in-1 multi-instrument feature set. The architectural difference is the ADC: the MSO3054X uses an 8-bit native ADC with up to 12-bit ERES; the MSO3000HD-series uses UNI-T’s R12™ native 12-bit ADC at full bandwidth. Choose the MSO3054X when 500 MHz bandwidth and 12-protocol decode breadth (including aerospace buses) are the priorities. Choose an MSO3000HD-series scope when the design requires native 12-bit resolution at full bandwidth — for example, ripple-on-bias measurement on a 400 V DC rail where the signal of interest sits on a large DC offset that 8-bit dynamic range cannot resolve cleanly.
