With the innovative Ultra Phosphor 3.0 technology achieving an impressive 1,500,000 wfms/s capture rate and 256 levels of color temperature display, the MSO5104HD excels at capturing elusive signal anomalies that other oscilloscopes might miss.

Engineered for modern test environments, the MSO5104HD combines 4 analog channels and 16 digital channels with up to 500 Mpts memory depth, while integrating nine instruments into one cost-effective package. The intuitive 10.1-inch capacitive multi-touch screen with gesture support streamlines workflow and improves productivity. Whether you're working in power electronics, semiconductor testing, or advanced R&D applications, the MSO5104HD provides the measurement accuracy, analysis capabilities, and intuitive operation needed to solve your most challenging signal integrity problems.

The MSO5104HD's 12-bit ADC technology delivers 4096 quantization levels—16 times higher than conventional 8-bit oscilloscopes—giving you remarkable vertical resolution for detecting subtle signal details. This high-resolution architecture can be further enhanced with the ERES (Enhanced Resolution) feature, which increases vertical resolution up to 16-bit. By combining the 12-bit ADC with 4-bit ERES, measurement accuracy is significantly improved, allowing for fine display of intricate waveform details.

With a remarkably low noise floor of only 75 μVrms at full bandwidth, the instrument effectively suppresses out-of-band noise and reduces inherent noise interference with the real signal. This ensures exceptional measurement accuracy for your most demanding applications, making the MSO5104HD ideal for precision measurements in power electronics, sensor signal analysis, and semiconductor characterization where small signal variations are critical.

With Ultra Phosphor 3.0 technology, the MSO5104HD achieves industry-leading waveform capture rates of up to 1,500,000 waveforms per second in sequence mode. This exceptional performance, coupled with 256 levels of color grading, dramatically improves your ability to visualize signal behavior and identify transient anomalies that could be missed by conventional oscilloscopes. The 8-channel parallel graph mapping with 20 Gbps processing rate ensures you'll never miss critical signal events, making the MSO5104HD invaluable for debugging high-speed digital designs and characterizing complex signal interactions.

The MSO5104HD combines nine instruments in a single compact unit, providing exceptional value and conserving valuable bench space. Beyond its core oscilloscope functionality, it integrates a logic analyzer, function/arbitrary waveform generator, spectrum analyzer, digital voltmeter, frequency counter, protocol analyzer, Bode plot analyzer, and power analyzer. This comprehensive integration accelerates testing workflows by eliminating the need to transfer signals between multiple instruments, maintaining signal integrity throughout the measurement process and reducing overall test setup complexity.

Equipped with extensive serial bus triggering and decoding capabilities, the MSO5104HD simplifies debugging of complex embedded systems. With support for 15 protocol standards including I²C, SPI, CAN, CAN-FD, LIN, FlexRay, and aerospace protocols, engineers can readily analyze communication issues at both physical and protocol levels. The event list function provides time-correlated views of decoded data alongside analog waveforms, enabling rapid identification of timing-related protocol problems. Additionally, the smart search function helps locate specific data packets or error conditions across long acquisitions.

The MSO5104HD offers specialized power analysis capabilities critical for modern power electronics design and testing. Comprehensive measurement sets include power quality, harmonic analysis, switching loss, safe operating area (SOA), modulation analysis, and ripple analysis. Engineers can quickly connect voltage and current probes to test points and receive immediate visualization of key power parameters. This integrated approach eliminates the need for separate power analyzers and provides real-time insights into power system performance, efficiency, and compliance with regulatory standards.

The zone trigger function provides an intuitive visual method for isolating specific signal behaviors that would be difficult to capture with conventional trigger conditions. Using touch or mouse gestures, you can simply draw a rectangle on the screen to define a "must intersect" or "must not intersect" zone. The oscilloscope then triggers only when signals enter or avoid these defined areas. This approach dramatically simplifies the process of isolating complex signal behaviors, reducing setup time and accelerating debugging of intermittent issues.

The MSO5104HD offers 56 types of precise parameter automatic measurements covering multiple dimensions such as voltage, frequency, phase, and power. It integrates advanced parameter statistics and trend graph visualization analysis functions, providing a comprehensive and multi-dimensional display of signal characteristic changes, achieving professional-level deep insights and efficient data interpretation.

The built-in spectrum analyzer function features standard enhanced FFT with up to 4 Mpts for 4-channel signal analysis, with a frequency range from 0 to 2.5 GHz. Advanced features include waterfall curves for visualizing frequency changes over time, 4 traces and 4 detection methods, and comprehensive marker options including auto, manual, and threshold types. This powerful spectral analysis capability enables engineers to identify EMI issues, analyze signal harmonics, and characterize frequency domain performance without requiring a separate spectrum analyzer.

The MSO5104HD includes powerful FIR filtering capabilities with continuously adjustable bandwidth settings. This allows you to effectively filter out noise and interference within the 50 Hz to 500 MHz range, ensuring cleaner signal acquisition and more accurate measurements. Whether you're working with sensitive analog circuits or analyzing noisy digital signals, the flexible filtering options help isolate the signals of interest and suppress unwanted components.

For applications requiring precise timing measurements, the MSO5104HD provides comprehensive timing analysis capabilities. This functionality is essential for verifying timing relationships in digital buses and ensuring compliance with communication protocols. The oscilloscope can analyze parameters like pulse width, amplitude, edge transitions, setup time, and hold time for various signals and protocols, including I²C, SPI, and CAN. Additionally, it supports exporting conformance test reports to document compliance with timing specifications.

The MSO5104HD features hardware-accelerated mask testing capabilities that significantly accelerate compliance and reliability testing. Using the 6σ (Six Sigma) standard, which requires a defect rate of no more than 3.4 defects per million opportunities, the oscilloscope's ultra-high hardware capture rate can complete waveform tests that meet these standards within 1 second instead of several hours. This dramatic performance improvement streamlines validation testing and ensures your designs meet rigorous quality standards.
