The MSO2304X is a 300 MHz, four-channel mixed-signal oscilloscope.

With 5 GSa/s real-time sample rate, 100 Mpts of memory depth, 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 MSO2304X integrates 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 four-channel power-electronics validation, switching-converter characterization, and high-bandwidth mixed-signal debug at the top of the MSO2000X line, the MSO2304X delivers 300 MHz of analog bandwidth on the same 5 GSa/s, 100 Mpts platform that the 100 and 200 MHz siblings carry. Calculated rise time falls to ≤1.17 ns — fast enough to capture switching-edge detail on point-of-load converters and DC-DC supplies where slower scopes round the gate-drive waveform.

Detailed Features

Nine Instruments in One

The MSO2000X platform 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), 2.5 GHz spectrum analyzer (FFT up to 4 Mpts), 4-digit digital voltmeter, 7-digit hardware frequency counter, multi-protocol serial-bus analyzer, Bode plot analyzer (optional, paired with the AWG for closed-loop sweep), and power-electronics analyzer (optional). For power-electronics design teams characterizing converter efficiency, harmonic distortion, and switching loss in the same bench session, the integration of optional power analysis with the four-channel acquisition path means one instrument captures the gate-drive waveform and computes the switching loss across the cycle — replacing a separate power analyzer for design-phase work.

High-Speed Acquisition — 5 GSa/s, 100 Mpts

The 5 GSa/s real-time sample rate (interleave mode) and 100 Mpts of acquisition memory hold full waveform fidelity across the 300 MHz analog bandwidth. Standard capture rate runs up to 500,000 wfms/s; in Sequential Mode — the segmented-memory acquisition mode that conditions captures on a trigger event — capture rate climbs to 2,000,000 wfms/s, holding up to 125,000 frames of uninterrupted hardware real-time waveform recording for post-capture replay and analysis.

ERES (enhanced resolution) extends effective vertical resolution from the 8-bit native ADC up to 12-bit when bandwidth headroom is available — useful for low-amplitude work where quantization noise would otherwise obscure detail on switching ripple, sensor outputs, or jitter analysis.

Ultra Phosphor 3.0 — 256-Level Grayscale Persistence

Ultra Phosphor 3.0 is UNI-T’s third-generation waveform-mapping architecture, combining parallel FPGA acquisition with 256-level grayscale intensity grading. Throughput is five to ten times higher than the previous-generation pipeline, and acquisition dead time drops below 1 µs — the scope captures 1.17 ns fast-edge signals at 2,000,000 events per second in Sequential Mode without missing the rare-event bracket between redraws. The 256-level intensity grading shows signal frequency-of-occurrence directly: frequent waveforms appear brighter, infrequent ones dimmer, making it intuitive to distinguish normal behavior from intermittent faults during long bench captures.

Built-In Spectrum Analyzer — FFT to 4 Mpts

The standard enhanced-FFT spectrum analyzer covers 0 Hz to 2.5 GHz with up to 4 Mpts of FFT length, four-channel signal analysis, four trace types (Normal, Average, Max Hold, Min Hold), and four detection modes. Marker functions cover Auto, Manual, and Threshold with a marker-point list, plus a waterfall display for tracking spectral activity over time. Use it to identify harmonics, characterize EMI signatures during pre-compliance sweeps, verify clock-signal purity on embedded designs, or analyze modulated signals — without paying for a separate spectrum analyzer.

Protocol Analysis — 9 Bus Types Across Four Domains

The MSO2000X covers nine protocol types across four bus domains: computer serial (RS-232/UART, I²C, SPI — standard), automotive serial (CAN, CAN-FD, LIN, FlexRay — optional), automotive sensor (SENT — optional), and audio (I²S, Left-Justified, Right-Justified, TDM — optional). Triggering and decoding are integrated: trigger on a frame error, an identifier match, a CRC failure, or a missing-ack condition, and the decode displays inline with the captured waveform. Up to four simultaneous decodes plus parallel-bus decoding (up to 18 bits, mixed analog and digital channels) cover most embedded-systems and automotive bus-validation workflows in one instrument.

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

The optional MSO2000X-AWG package adds a 50 MHz dual-channel function and arbitrary waveform generator with 16-bit vertical resolution and 250 MSa/s sample rate, 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 200 standard arbitrary waveforms (Sinc, ExpRise, ExpFall, Cardiac, Gauss, Lorentz, HaverSine, and others). AM, FM, ASK, FSK, and sweep modulation are supported, and on-screen oscilloscope captures can be loaded directly into the AWG for stimulus-response replay.

Power Analysis (Optional) — Five Measurement Types

For wide-bandwidth power-electronics validation, 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 on the AC input, surge-current characterization on inrush events, ripple analysis on output rails, and loop analysis (paired with the optional AWG and Bode plot) for closed-loop converter stability sweeps. At 300 MHz of analog bandwidth, the package handles the switching frequencies that point-of-load converters, motor drives, and DC-DC supplies 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 — two zones supported, sourced from any of CH1 through CH4. Combined with the eleven trigger types (edge, pulse width, ramp, runt pulse, over-amplitude pulse, delay, timeout, duration, setup & hold, Nth edge, code pattern), the zone trigger turns rare-event hunting into a defined acquisition condition rather than a wait-and-watch exercise.

56 Automated Measurements with Histogram and Trend Statistics

The MSO2000X provides 56 automated measurement parameters on the analog channels — voltage, time, frequency, statistical, and burst measurements — with up to 27 measurements displayed simultaneously and per-channel parameter snapshots showing 39 single-channel measurements at once. Measurement statistics include mean, maximum, minimum, standard deviation, count, tendency chart, and bar chart (histogram) views. The histogram surfaces parameter distribution visually; the tendency chart shows parameter drift over time — useful for jitter analysis, long-capture characterization, and pass/fail evidence reports.

Fast Fuzzy Autoset — Sub-Second All-Channel Setup

The MSO2000X uses a fuzzy-logic autoset algorithm built around the 7-digit hardware frequency counter and multi-channel parallel processing. All-channel autoset completes in under 1.5 seconds; single-channel autoset completes in under 1 second — useful on production-line spot-check work and education-track lab benches with frequent setup changes.

10.1-Inch Capacitive Multi-Touch UI

The 10.1-inch 1280×800 HD capacitive multi-touch display supports the standard touch gestures (click, slide, zoom, edit, drag) for direct waveform manipulation, plus rectangle-draw for zone triggering. Multi-window layout lets multiple display panels (waveform, FFT, decode list, measurement table) be dragged and resized independently. Traditional knob-and-key controls remain for engineers who prefer them, and external mouse and keyboard input is supported via USB. HDMI output mirrors the display to an external monitor or projector — useful for instructor-led demonstrations and engineering team reviews.

Connectivity, SCPI, and WebServer Remote Control

USB 3.0 Host (one front, two rear), USB 3.0 Device (rear), 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). The instrument supports the full SCPI command set, and the built-in WebServer provides browser-based remote control from PC or mobile.

FAQ's

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

Standard capture rate (500,000 wfms/s) is the rate at which the MSO2304X 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 125,000 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 and the captures-per-second matter.

Is the MSO2304X a 12-bit oscilloscope?

No. The MSO2304X has an 8-bit native ADC with up to 12-bit effective resolution via ERES (enhanced resolution) when bandwidth headroom is available. For native 12-bit acquisition at full bandwidth and full sample rate, see UNI-T’s HD-series oscilloscopes (UPO1000HD, UPO2000HD, MSO1000HD, MSO3000HD, MSO5000HD, MSO8000HD), which use the R12™ native 12-bit ADC architecture.

Are the 16 digital channels included?

The 16-digital-channel logic-analyzer front end is built into the chassis, but using it requires the optional UT-M15 probe pod. Without the UT-M15, the MSO2304X operates as a 4-channel digital storage oscilloscope.

What’s included with the AWG option?

The MSO2000X-AWG package adds a 50 MHz dual-channel function and arbitrary waveform generator with 16-bit vertical resolution, 250 MSa/s sample rate, and 200 built-in arbitrary waveforms. The Bode plot analyzer is included with the AWG package — it uses the AWG for stimulus and the scope channels for response measurement.
