Overview

The MSO8804HD is a lab-grade 8 GHz 4-channel mixed signal oscilloscope built on UNI-T’s R12™ native 12-bit ADC architecture, with a 20 GSa/s real-time sample rate (half-channel mode), 500 Mpts standard memory depth (expandable to 2 Gpts), and a calculated rise time of ≤55 ps. The 12-bit resolution holds across the full 8 GHz bandwidth with no ERES averaging step or sample-rate trade-off, and the front-end’s effective number of bits stays >7 bits at full system bandwidth. Sustained capture rate is ≥1,000,000 wfms/s, with segmented Sequential Mode storing up to 520,000 frames of hardware real-time waveform history.

For high-speed digital validation, signal-integrity engineering, and conformance pre-screening at the bandwidth tier where eye-diagram detail and rise-time fidelity become the differentiating measurement — PCIe Gen2 reference clocks, USB 2.0 high-speed lanes, 100/1000 Mbps Ethernet timing, and emerging high-speed serial interfaces — the MSO8804HD pairs an 8 GHz analog front end with a 12-bit native ADC and a 15.6-inch FHD multi-window touchscreen. Built on UNI-T’s self-developed AFE ASIC and seventh-generation oscilloscope platform.

Key Features

Detailed Features

UltraAcq® and Sequential Mode — ≥1,000,000 wfms/s for Rare-Event Hunting

The MSO8804HD captures up to 300,000 wfms/s in UltraAcq® standard acquisition mode, climbing to ≥1,000,000 wfms/s with Sequential Mode enabled. Sequential Mode segments deep memory (500 Mpts standard, 2 Gpts optional) into trigger-conditioned acquisition windows, minimizing dead time between captures and recording up to 520,000 frames of hardware real-time waveform history.

After acquisition, captured frames replay individually, animate as a sequence, or display up to 40 segments simultaneously (45° perspective, overlap, superimpose, or stitch) — turning rare-event hunting on a live serial bus from a watch-and-wait debug session into an analysis-after-capture exercise.

Optimized Channel Architecture — 8 GHz Half-Channel, 4 GHz Full-Channel

The MSO8804HD’s analog front end delivers the full 8 GHz bandwidth and 20 GSa/s sample rate in half-channel mode (C1 alone, C3 alone, or C1+C3 simultaneously); in full four-channel mode, the bandwidth is 4 GHz and the sample rate is 10 GSa/s. Channel-to-channel isolation is ≥600:1 from DC–4 GHz across any combination, and ≥500:1 above 4 GHz with C1 and C3 simultaneously enabled. Both modes operate on the same instrument without a configuration license or front-end module change.

52 Automated Measurements with Histogram, Trend, and Statistical Analysis

52 automated measurement types cover voltage, time, frequency-domain, and area-under-curve calculations, with quick-Meas single-channel parameter snapshots and trace-based visualization for measurement evolution over long capture windows. Histogram and trend-chart displays surface measurement statistics over time — useful for signal-integrity work where the parameter distribution matters as much as a single instantaneous value (jitter on a long-running clock line, rise-time consistency across temperature corners). Burst-region measurement localizes the window to a specific event rather than averaging across the full capture, supporting non-stationary signals where the measurement has to be conditioned on a trigger.

16 Digital Channels with the UT-M15 Probe Pod (Optional)

The 16-digital-channel logic-analyzer front end is built into every MSO8000HD chassis as hardware-standard. The optional UT-M15 logic probe pod activates it — separate high/low 8-bit connectors, direct attachment to 8×2 square-pin headers (2.54 mm pitch), 1.25 GSa/s digital sample rate, 3.2 ns minimum detectable pulse width, 101 kΩ ±1% input impedance.

Digital and analog channels share the same time base, trigger system, and display, so a falling SPI clock edge and the analog-domain crosstalk it causes show up in the same time-correlated frame — mixed-signal capture in one instrument eliminates the time-correlation problem of separate-instrument workflows.

15.6-Inch FHD Multi-Window Touch UI and WebServer

A 15.6-inch FHD (1920×1080) capacitive multi-touch display anchors the front-panel experience — the largest screen UNI-T ships on a bench scope. Touch, drag, pinch-to-zoom, and gesture controls handle common waveform operations, while traditional knobs and shortcut keys provide the fine-control surface bench engineers expect; Bluetooth keyboard and mouse are supported as a third modality.

Dynamic multi-window operation is the differentiator at the screen-size tier: drag and rearrange windows, resize by dragging edges, pin pop-up windows, extend windows beyond screen edges for multi-monitor setups, and run cursor-based measurements in separate windows from the primary waveform view. The built-in WebServer adds browser-based remote control over LAN (SCPI commands, waveform export, screen capture) from any PC, tablet, or mobile device on the network.

Applications

High-Speed Digital R&D and Signal-Integrity Engineering

For embedded systems work at the bandwidth tier where rise-time fidelity and eye-diagram detail become the differentiating measurement — PCIe Gen2 reference clocks, USB 2.0 high-speed lanes, DDR4 timing, 100/1000 Mbps Ethernet, and emerging high-speed serial interfaces — the MSO8804HD pairs an 8 GHz analog front end with 12-bit native acquisition and Sequential Mode capture density. Optional jitter analysis and eye-diagram packages decompose total jitter into random and deterministic components, PAM-N analysis covers PAM-3 through PAM-7 for next-generation digital communications, and the embedded MATLAB compiler executes custom analysis scripts on-instrument without data-export round-trips.

Test Laboratory and Consultancy Compliance Work

For test labs and consulting practices that document compliance and pre-compliance characterization on customer-supplied DUTs, the MSO8804HD’s automated USB 2.0 and Ethernet conformance test packages collapse multi-day manual measurement sequences into single-button automation runs, with pass/fail reports including margins, parameter results, and waveform snapshots. Customizable limit templates handle association-defined criteria (USB-IF, IEEE 802.3) alongside user-defined tolerance windows. Combined with the 52-parameter measurement set and full SCPI automation, the same instrument supports both interactive characterization and unattended overnight regression testing.
