Overview

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.

Key Features

Detailed Features

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.

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.

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.

Applications

For R&D Engineers

• For mainstream R&D validation at 350 MHz, the MSO3034X covers ARM Cortex-A microcontroller debug, mid-speed FPGA reference designs, four-channel time-correlated mixed-signal work (with the UT-M15 logic probe pod), and 12-protocol decode across computer, automotive, audio, and aerospace buses — covering a broad envelope of design-validation work in one instrument.
• Time-correlated mixed-signal capture across analog channels and 16 digital lines (with the UT-M15 probe pod) on the same instrument and the same trigger event.

For Power Electronics Engineers

• For switching-mode power-supply validation and DC-DC converter characterization at moderate switching frequencies, the MSO3034X pairs four-channel acquisition with the optional six-measurement power-analysis suite, the optional 50 MHz AWG with Bode plot analyzer for closed-loop stability sweeps, and 500 Mpts memory for multi-cycle transient capture — covering the full converter-design workflow on one instrument.
• Optional six-measurement power-analysis package: power quality, harmonic analysis, switching loss, ripple analysis, loop analysis, and safe operating area visualization.
• Four-channel acquisition supports vIN / vOUT / IL / vGS measurement on switching converters and DC-DC supplies in a single time-correlated capture.
• Optional dual-channel 50 MHz AWG with Bode plot analyzer for closed-loop frequency-response and stability sweeps on power-supply controllers.

For Education and Teaching Labs

• For undergraduate and graduate-track engineering labs running advanced embedded-systems, signals-and-systems, and power-electronics-introduction coursework, the MSO3034X delivers 350 MHz of analog bandwidth alongside the integrated nine-instrument suite and 12-protocol decode — covering scope, FFT spectrum, protocol decode, AWG-driven stimulus, and power-electronics fundamentals in one teaching-bench footprint, with HDMI projection for instructor-led demonstrations.
• Nine integrated instruments cover most of the bench-instrument curriculum on one operator-training surface, from analog-and-digital fundamentals through introductory power-electronics topics.
• HDMI output mirrors the display to a projector or external monitor for instructor-led demonstrations.
• WebServer remote access lets students view captures and run measurements from networked classroom devices without crowding the bench.
• 10.1-inch capacitive multi-touch UI plus traditional knob-and-key controls support a range of student comfort levels with bench-instrument operation.

Frequently Asked Questions

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 MSO3034X 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.

Should I size up to the MSO3054X instead?

If your fastest signal edges are below ~300 MHz and you don’t need deeper visibility into 500 MHz analog content, the MSO3034X has the same 5 GSa/s, 500 Mpts platform, the same 12-protocol decode set, and the same Ultra Phosphor 3.0 waveform-mapping engine as the MSO3054X — the 350 MHz bandwidth is the only meaningful difference on the spec sheet. The MSO3054X is worth the step-up when you’re working at the rise-time edge of 500 MHz analog signal-integrity, characterizing higher-bandwidth switching converters, or running closed-loop stability sweeps on wide-bandgap (GaN/SiC) power converters where the additional headroom shows up in measurement accuracy.
