The SIGLENT SDM4065A is a 6½‑digit (2,200,000‑count) dual‑display digital multimeter featuring a 5" full‑color touchscreen (800×480) and real‑time True‑RMS measurement for AC/DC voltage (200 mV–1000 V) and current (200 µA–10 A). With up to 50 000 rdgs/s throughput and 0.001 PLC minimum aperture, it delivers both high‑speed and high‑precision performance.

Siglent's NEW SDM4065A 6½ Digit High-Precision Digital Multimeter with Dual Display, Fast Logging, and Advanced Visualization

Step up to ultra-precise measurements with the Siglent SDM4065A, a powerful 6½ digit digital multimeter designed for professional-grade applications in research, calibration, manufacturing, and automated testing. With 75 ppm basic DC voltage accuracy, True-RMS AC measurements, and a vivid 480×800 color display, the SDM4065A delivers outstanding accuracy and usability in one compact instrument.

The SDM4065A supports a comprehensive range of electrical measurements, including DC/AC voltage up to 1000 V, current up to 10 A, 2-wire and 4-wire resistance up to 100 MΩ, capacitance, frequency, diode and continuity tests, and temperature measurements via thermocouples and RTDs. It also enables user-defined sensor inputs for custom applications.

Ideal for both real-time analysis and long-duration testing, the SDM4065A features:

High-speed acquisition with flexible sampling modes
Data logging to memory or file, with support for millions of readings
Dual-display mode for viewing two parameters simultaneously
Built-in math/stat functions, including limits, dB/dBm, relative value, and statistics
Multiple display modes: numeric, bar graph, trend chart, and histogram

Designed for integration into modern labs and production setups, the SDM4065A includes USB Host/Device, LAN, and optional GPIB interfaces, and is fully SCPI programmable. It's compatible with PC software for remote control and data visualization.

Whether you're debugging, characterizing, or automating, the SDM4065A offers the precision and flexibility to tackle complex measurement tasks with ease.

Application Examples

Electronic Design and Validation

Perfect for validating precision analog or mixed-signal circuits, the SDM4065A offers stable long-term logging, auto-zero for accurate low-voltage measurements, and user-defined math functions for fast insight.

Production Testing and QA

Automate high-throughput testing with SCPI control over LAN, USB, or GPIB (optional). The optional SC1016 scanner card enables up to 16-channel scanning, making it ideal for multichannel voltage or resistance tests in PCBA quality assurance or thermal cycling chambers.

Research and Calibration Labs

With a minimum aperture time of 0.001 PLC and statistical functions such as standard deviation and span, researchers can capture even the smallest fluctuations in sensor data, environmental measurements, and power profiles.

Power Supply and Battery Testing

Use dBm/dB math, logging, and histogram modes to evaluate load regulation, voltage drift, and ripple under dynamic conditions. The high-speed trend chart provides real-time insight during warm-up and transient events.

Environmental Testing

Temperature measurement support with customizable reference points and multiple units (°C, °F, K) make it well-suited for controlled chamber tests and industrial sensor monitoring.

Energy and Power Electronics Testing

The SDM4065A’s high input impedance, accurate DC/AC voltage and current ranges, and support for dB/dBm measurements make it ideal for analyzing power converters, inverters, and power supply modules. Its dual-display function allows simultaneous voltage and current readings, while data logging helps capture startup behavior, efficiency variations, or thermal drift over time.
