The SDM3055’s performance and ease of use make it an outstanding choice for professionals who demand precise, consistent, and trustworthy measurement results—day after day, test after test.

Visual Data Analysis with the Histogram Display

The Siglent SDM3055 includes a powerful histogram display function that provides an instant visual representation of measurement distributions. This feature allows users to quickly observe how measured values vary over time and to identify trends, outliers, or drift in the signal.

Instead of analyzing only numerical statistics, the histogram presents data in a bar graph format, showing how often specific measurement values occur within a defined range. This is particularly useful for detecting stability issues, component tolerances, or fluctuations in production testing.

By offering both graphical and numerical insights, the SDM3055 helps engineers make faster, more informed decisions without the need for external software. Combined with its high sampling rate and internal data logging capabilities, the histogram display transforms the multimeter into a powerful tool for quality control, long-term monitoring, and statistical analysis directly on the instrument.

Trend Chart for Time-Based Analysis

The Trend Chart function of the Siglent SDM3055 provides a dynamic graphical view of measurement results over time, allowing users to easily observe signal stability, drift, or gradual changes in voltage, current, or resistance. This real-time plotting feature is ideal for long-term monitoring and characterization of components or circuits under varying conditions. With adjustable time scales and automatic scaling options, the Trend Chart helps transform numeric readings into clear visual trends—making it easier to detect patterns, anomalies, or performance fluctuations directly on the instrument’s color display.

Dual Display for Enhanced Efficiency

The Siglent SDM3055 features a practical dual display mode that allows two measurement parameters to be shown simultaneously on the screen. For example, users can view voltage and current, or frequency and amplitude, at the same time—without switching modes or losing data continuity. This capability streamlines testing and analysis, especially in applications where correlated measurements are essential. With its bright, 4.3-inch TFT-LCD screen, the SDM3055 delivers clear, real-time visibility of both readings, improving workflow efficiency and making complex measurements faster and more intuitive.
