The Siglent SDM3065A-SC is a 50000 rdgs/s high-performance 5½ digit digital multimeter equipped with the SC1016 16-channel scanner card, making it ideal for automated, multi-point measurements in R&D, production testing, and quality control. Featuring a crisp 4.3-inch TFT display, the scanner card has a fast reading rate of up to 150 rdgs/s, and built-in data logging capabilities, the SDM3065A-SC delivers reliable performance and streamlined operation for high-throughput testing environments.

Siglent’s new SDM4065A‑SC combines a 5½ digit bench multimeter with the SC1016 16‑channel scanner card into a single, turnkey instrument. You’ll get 150 ppm basic DCV accuracy and True‑RMS AC measurements across DC/AC voltage up to 1000 V, current to 10 A, 2‑ and 4‑wire resistance to 100 MΩ, plus capacitance, frequency, diode/continuity tests and RTD/thermocouple temperature—all controlled from the responsive 5″ touchscreen. With the scanner card engaged you can automatically sequence up to 16 measurement points at a combined 150 readings per second, capturing every channel without rewiring, while the built‑in logger stores up to two million readings for long‑term trends. Dual‑display, bar, trend and histogram modes, full math/statistics (Min/Max/Avg/Std Dev, limits, dB/dBm, relative), and USB, LAN and optional GPIB connectivity with SCPI support make the SDM4065A‑SC the ultimate solution for fully automated, high‑throughput test and quality‑control environments.

Built for automation and connectivity, the SDM4065A-SC includes USB, LAN, and optional GPIB interfaces, and supports SCPI remote control and EasyDMM-X software. With built-in dual display, statistics functions, and advanced visualization modes such as trend charts and histograms, it's engineered to simplify even the most complex tasks.

Scanner card SC1016

The scanner card SC1016 is a multiplexer that provides multi-point measurement capabilities to the SDM4065A-SC. The scanner features 12 multi-purposes + 4 current channels and supports the following measurement functions: DCV, ACV, DCI, ACI, 2WR, 4WR, CAP, FREQ, DIODE, CONT and TEMP (RTD and Thermocouple). It provides a convenient and versatile solution for test applications that require multiple measurement points or signals and is an ideal tool for R&D burn-in and production testing.

Application Examples

1. Automated PCB Power‑Rail Verification
In a production line for complex PCBs—such as motherboards or power‑management modules—each board may require verification of a dozen separate voltage rails, plus current checks on high‑power domains. With its built‑in SC1016 scanner card, the SDM4055A‑SC can automatically step through up to 12 voltage or resistance channels (e.g. 3.3 V, 5 V, 12 V rails and pull‑up resistors) and four dedicated current channels (up to 2 A each) at a combined rate of up to 150 rdgs/s. That means a complete multi‑rail check in under 200 ms, saving minutes per board compared to manual probe switching—and it logs every channel with timestamps for traceable quality records.

2. Multi‑Sensor Environmental Characterization
For R&D teams characterizing thermal or humidity sensor arrays, the SDM4065A‑SC’s 16‑channel scanner lets you read 12 thermocouples or RTDs in parallel while reserving channels for reference currents or calibration resistors. At 150 rdgs/s total, you can cycle through all sensors every 100 ms, capturing temperature profiles across an environmental chamber. Coupled with its 2 million‑point logger and trend‑chart display, you get both high‑speed snapshots and long‑duration drift analysis without manual intervention.

3. Battery‑Cell Balancing in Pack Development
When developing multi‑cell battery packs, engineers must monitor each cell voltage and cell‑stack current under charge/discharge cycles. The SC1016 card handles up to 12 individual cell taps for voltage, plus four channels for current measurement (via external shunts), all in one instrument. At ~12 channels × 12.5 rdgs/s per channel, you still get sub‑second updates across the pack—fast enough to detect imbalance or thermal anomalies during fast‑charge testing, and to log data for SOC/SOH algorithms.

4. Automated Burn‑In and Reliability Testing
In burn‑in ovens or reliability test fixtures, dozens of devices under test need periodic electrical checks—resistance, leakage current, or diode functionality—over tens of hours. The SDM4065A‑SC’s scanner card lets you define channel ranges and settle times once, then run hands‑free for the full test duration. Its 150 rdgs/s scanning speed, combined with programmable trigger delays and VMC synchronization, ensures every channel is measured at precise intervals, and its histogram mode highlights outlier devices immediately.

5. High‑Volume Calibration Lab Workflows
Calibration labs routinely verify hundreds of DMMs, transducers, or sensors each week. By wiring each device’s output to a separate channel on the SC1016, the SDM4065A‑SC can step through a calibration rack automatically—applying known references (voltage, current, resistance) and capturing the DUT’s response in one sweep. With its full SCPI support, the entire procedure can be scripted in your lab management software, delivering pass/fail certificates with minimal operator time.
