The MSO3034X is a 350 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 MSO3034X 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 350 MHz mixed-signal R&D validation, four-channel power-electronics characterization, and engineering-team benches that need protocol decode, spectrum, AWG, and power analysis alongside scope acquisition, the MSO3034X is the entry SKU into UNI-T’s MSO3000X line at the most accessible price point. The 500 Mpts memory holds long acquisition windows for protocol-event hunting and switching-supply transient capture without sacrificing sample rate, and the 12-protocol decode set includes computer, automotive, audio, and aerospace bus families that mid-tier scopes commonly leave on the option list.

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 mid-tier R&D benches consolidating across protocol decode, spectrum analysis, AWG-driven stimulus, and four-channel scope work in the same session, the integration eliminates the cable-swap-and-instrument-handoff cycle that breaks engineering flow on multi-instrument bench setups, and the optional power-analysis package adds a working power-electronics analyzer alongside the existing acquisition path.

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 350 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 holds long acquisition windows at full sample rate — the difference between catching an intermittent fault on a 100 ms capture and missing it because the memory was saturated at 5 ms. For protocol-event hunting on high-traffic CAN-FD or FlexRay buses, switching-supply transient analysis across multiple cycles, and long-term jitter characterization, the deep-memory budget removes the sample-rate vs. window-length trade-off that limits mid-tier 100 Mpts scopes.

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

The MSO3034X 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. For wider-bandwidth designs requiring native 12-bit resolution at full bandwidth, see UNI-T’s MSO3000HD-series scopes, which use the R12™ native 12-bit ADC architecture at the same 200–500 MHz bandwidth tier.

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 switching-mode power-supply validation, motor-drive characterization, and DC-DC converter design at moderate switching frequencies, the optional power-analysis package adds a six-measurement suite (power quality, harmonic analysis, switching loss, ripple analysis, loop analysis, safe operating area) to the four-channel acquisition path. The same scope that captures the gate-drive waveform also computes switching loss across the cycle, replaces a separate power analyzer for early-stage characterization, and pairs with the Bode plot analyzer (included with the optional AWG) for closed-loop stability sweeps on switching converters.

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.
