SIGLENT SDM4065A-SC 6.5-DIGIT DIGITAL MULTIMETER WITH SCANNER

Overview

The Siglent SDM4065A-SC is a premium-grade, high-precision 6.5-digit (2,200,000 count) benchtop digital multimeter integrated with a 16-channel multiplexer scanner card (SC1016). Engineered to meet the most demanding requirements for high-accuracy, multi-point, and automated measurement systems, this instrument combines a wide array of mathematical functions with an exceptional 5-inch TFT-LCD capacitive touch screen.

By incorporating the SC1016 scanner card natively, the SDM4065A-SC transforms from a standard benchtop multimeter into a versatile, high-speed data acquisition system. This system is ideal for component characterization, environmental burn-in testing, quality control, and production-line testing. With an extreme reading rate of up to 50,000 rdgs/s, an integrated 50 kSa/s digitizing function, and a modern, user-friendly UI, the SDM4065A-SC delivers deep measurement insights without compromising on setup speed or complexity.

Product Features

Real 6.5-Digit Resolution & 35 ppm Accuracy

Equipped with a true 2,200,000 count reading resolution and a basic DC voltage accuracy of 35 ppm (0.0035% of reading + 0.0006% of range). It ensures pristine, highly dependable, and repeatable measurements for sensitive analog circuits, calibration tasks, and high-spec components.

Integrated 16-Channel SC1016 Scanner Card

The included SC1016 multiplexer scanner card provides 12 multi-purpose channels and 4 dedicated current channels. It supports a comprehensive range of configurations—including 2-wire and 4-wire resistance, DCV, ACV, DCI, ACI, capacitance, frequency, diode, continuity, and temperature measurements (RTD/Thermocouple)—allowing you to monitor multiple test points simultaneously.

High-Speed Digitize Function

Features an integrated digitizer with a sample rate of up to 50 kSa/s and a 10 kHz bandwidth. This function allows engineers to acquire up to 2 million points in a single acquisition run, making it ideal for capturing transient signals, fast power-up behaviors, and dynamic current profiles.

5-inch Touch Display & Multiple Visualization Modes

Featuring an 800x480 resolution capacitive touch display paired with an intuitive UI. View your data across four distinct display modes: traditional numerical values, a real-time bar meter, dynamic trend charts, or detailed histograms to quickly evaluate signal distribution and spot drift patterns.

Advanced Data Logging & Generous Memory

Configure custom data logging sessions with sample intervals ranging from 1 ms to 3600 s for up to 100 hours of continuous logging. Save up to 2 million readings directly to the onboard cache memory (512MB RAM with timestamp support) or up to 360 million points directly to internal files (256MB Nand Flash).

Complete Interface Suite & Remote Access

Equipped with standard USB Device, USB Host, and LAN interfaces, with an optional USB-GPIB adapter. It offers native remote access support for VNC servers and web browsers, as well as full compatibility with Siglent's EasyDMM-X host computer control and sampling software.
