Overview

The UNI-T MSO8804HD represents the pinnacle of mixed signal oscilloscope technology, delivering professional-grade 8GHz bandwidth with 20GSa/s real-time sampling and industry-leading 12-bit vertical resolution. Engineered for the most demanding high-speed digital design and validation applications, the MSO8804HD combines exceptional signal fidelity with comprehensive protocol analysis capabilities.

Featuring an ultra-low noise floor of ≤800μV and 7-bit ENOB at full bandwidth, this flagship instrument delivers measurement accuracy that rivals oscilloscopes costing twice as much. With support for 21+ serial protocols, advanced jitter analysis, and automated compliance testing, the MSO8804HD is the definitive solution for semiconductor design, 5G communications, automotive electronics, and aerospace applications.

The MSO8804HD features an intelligent channel architecture that maximizes performance when you need it most. For maximum bandwidth and sample rate (8GHz, 20GSa/s), the instrument operates in optimized dual-channel mode using channels C1, C3, or both simultaneously. This configuration is ideal for differential signal analysis, high-speed serial interfaces, and critical timing measurements where ultimate performance is essential.

When analyzing complex systems requiring three or four channels simultaneously, the MSO8804HD automatically provides 4GHz bandwidth and 10GSa/s sampling across all channels—still exceptional performance that exceeds most competing instruments. The intelligent architecture ensures you always get optimal performance for your specific measurement requirements.

The MSO8804HD's 12-bit analog-to-digital converter delivers 16 times finer vertical resolution than conventional 8-bit oscilloscopes, enabling precise characterization of high-speed digital signals, power integrity measurements, and weak signal analysis. Combined with Enhanced Resolution (ERES) mode, users can achieve up to 16-bit precision for the most demanding measurement applications.

The industry-leading noise floor of just 800μV at full bandwidth ensures that small signals remain visible above the noise, while the superior 7-bit ENOB at 8GHz maintains measurement accuracy even at maximum bandwidth. This exceptional signal integrity makes the MSO8804HD ideal for validating next-generation semiconductor designs and high-speed communication systems.

Supporting more than 21 serial protocols, the MSO8804HD eliminates the need for multiple specialized instruments. Standard protocol support includes RS-232/422/485/UART, SPI, I²C, CAN, and LIN, while optional packages add high-speed protocols like PCIe 2.0, USB 2.0, Ethernet, CAN-FD, FlexRay, and aerospace standards including MIL-STD-1553 and ARINC 429.

Real-time protocol decoding with color-coded overlays allows engineers to quickly identify communication errors, timing violations, and data corruption. The synchronized analog and digital views provide complete system visibility, enabling rapid debug of complex mixed-signal designs where protocol integrity depends on precise timing relationships.

The MSO8804HD's hardware-accelerated jitter analysis engine provides real-time separation of random and deterministic jitter components, eliminating the need for offline processing tools. Automated measurements include Total Integrated Error (TIE), period jitter, cycle-to-cycle jitter, and advanced decomposition into random jitter (RJ), deterministic jitter (DJ), and sub-components like data-dependent jitter (DDJ) and duty cycle distortion (DCD).

Real-time eye diagram generation with compliance templates enables immediate pass/fail assessment against industry standards. The comprehensive jitter analysis suite makes the MSO8804HD essential for validating high-speed serial interfaces, clock distribution networks, and timing-critical digital communication systems.

Supporting advanced pulse amplitude modulation from PAM-3 to PAM-16, the MSO8804HD addresses the growing complexity of next-generation high-speed digital communications. PAM-4 signaling, increasingly adopted in 400G Ethernet, PCIe 6.0, and DDR5 memory interfaces, requires sophisticated analysis capabilities that traditional oscilloscopes cannot provide.

The MSO8804HD's PAM-N analysis includes eye diagram generation for each amplitude level, comprehensive jitter and noise measurements, and automated parameter extraction. This advanced capability enables engineers to validate signal integrity margins, optimize equalization settings, and ensure compliance with emerging high-speed digital standards.

The MSO8804HD includes automated compliance test suites that eliminate manual configuration errors and reduce test time by up to 90%. Current support includes USB 2.0 and 10/100/1000 Mbps Ethernet protocols, with planned expansion to automotive Ethernet, MIPI, and PCIe standards.

Each compliance package provides guided setup wizards, automated test execution, and comprehensive pass/fail reporting with detailed margin analysis. Test results include waveform captures, parametric measurements, and compliance margins, enabling engineers to quickly identify and resolve interface issues while maintaining thorough documentation for regulatory submissions.

The MSO8804HD supports embedded MATLAB programming, allowing engineers to create custom analysis routines and visualizations directly on the instrument. This powerful capability eliminates the need to export data to external tools, enabling real-time processing of complex algorithms and immediate display of results.

The advanced filter designer supports multiple filter topologies including Butterworth, Chebyshev Type I/II, and Elliptic filters. Users can design custom filters using sampling methods, Remez algorithms, or window functions, enabling sophisticated signal conditioning and noise reduction for specialized measurement applications.
