MSO8804HD | Lab-Grade 8 GHz 4-Channel 12-Bit Mixed Signal Oscilloscope

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.

The MSO8804HD is the signal-integrity model of the MSO8000HD series. Its 8 GHz front end and ≤55 ps rise time are aimed at high-speed serial work: jitter decomposition and eye diagrams, PAM-3 through PAM-8 multi-level signaling, and automated compliance testing for USB 2.0, 100/1000BASE-T Ethernet, 100/1000BASE-T1 automotive Ethernet and MIPI D-PHY v1.2 (Optional). The same edge fidelity makes it the series choice for semiconductor and device characterization, where the transition itself is the measurement. 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.

SCPI Automation

Included as standard, the MSO8804HD speaks full SCPI over LAN, USB Device, and the built-in WebServer interface — LabVIEW, Python, and any SCPI-aware framework can drive the instrument for automated test sequences and unattended regression runs.

74 Automated Measurements with Histogram, Trend, and Statistical Analysis

74 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. 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 Serial and Signal Integrity

The MSO8804HD is built for the measurements where edge fidelity decides the answer. With 8 GHz on C1 and C3, ≤55 ps rise time and ≤150 fs RMS inherent jitter, the optional MSO8000HD-JITTER package separates random and deterministic jitter and builds real-time eye diagrams on PCIe Gen2, USB 2.0, Gigabit Ethernet and custom SerDes links. PAM-N analysis extends the same work to PAM-3 through PAM-8 signaling, where 12-bit resolution and >7 bits ENOB keep closely spaced levels apart. Pair it with the UT-PD6000 (6 GHz) or UT-PD4000 (4 GHz) active differential probe for differential lanes.

Compliance and Pre-Compliance Testing

For design teams checking a board before it goes to a test house, and for labs running compliance on customer DUTs, the optional packages automate USB 2.0, 100BASE-TX, 1000BASE-T, 100BASE-T1, 1000BASE-T1 and MIPI D-PHY v1.2 physical-layer tests. Reports carry pass/fail status, margins, parameter results and waveform snapshots, and multi-round validation tracks a fix across design revisions. With full SCPI automation the same instrument covers interactive characterization by day and unattended regression runs overnight.

Semiconductor and Device Characterization

Rise time, overshoot, settling and timing margins on fast devices need an instrument whose own edge is faster than the one being measured. The MSO8804HD’s ≤55 ps rise time, 20 GSa/s sampling and 74 automated measurements with histogram and trend statistics turn device characterization into a repeatable, scriptable measurement rather than a cursor exercise.

Wideband Communications Debug

8 GHz of real-time bandwidth and the standard enhanced FFT reach the sub-7 GHz bands used by 5G NR FR1 and current Wi-Fi, so RF bursts and the baseband or control signals around them are captured on one timebase for debug and validation.
