Siglent SDM4065A-SC 6.5 Digits 50000 rdgs/s digital multimeter + 16CH Scanner Card
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.
SDM4065A-SC — 6½ digit touchscreen multimeter
The SDM4065A-SC is the complete bench data-acquisition system: flagship 6½-digit, 50,000 rdgs/s measurement multiplexed across 16 factory-installed scanner channels — including four true current inputs — with time-stamped logging for calibration, burn-in and reliability work.
Every channel gets the flagship treatment: 6½ digits (2,200,000 counts) with autozero, digitize sampling to 50,000 rdgs/s with a 2-million-reading memory, and the complete function set — DC/AC voltage to 1000 V, current to 10 A, 2/4-wire resistance, capacitance, frequency and TC/RTD temperature. The factory-installed SC1016 spreads it across 16 channels (12 multi-purpose + 4 current), each with its own function and limits in the scan list, logged with timestamps and exported via USB/LAN and EasyDMM.

Application examples
Automated precision test systems
Flagship 6½-digit accuracy distributed over 16 scanned channels integrates into SCPI-driven production and calibration systems — multi-point functional test with metrology-grade numbers, no switching mainframe required.
Multi-channel calibration comparisons
Route references and DUT outputs through the scan list: autozero and 35 ppm basic accuracy compare every channel against your standard in one logged, time-stamped run.
Reliability and burn-in monitoring
Microvolt-level drift across many points over days — scanned unattended with per-channel limits, the four current channels measuring bias and leakage directly through shunts.
Transient capture between scan jobs
The same instrument digitizes at up to 50,000 rdgs/s when an inrush or power-up question appears, then returns to its scan list — one calibrated box for both duties.
A measurement system, not just a meter

Four views on a 5″ multi-touch display
Numerical, bar meter, trend chart and histogram — switch with a tap. True-RMS AC, 2/4-wire resistance, capacitance, frequency and TC/RTD temperature are all built in.

SC1016: 16 channels installed
The factory-installed scanner card multiplexes 16 channels — 12 multi-purpose (CH1–CH12) plus 4 dedicated current channels (CH13–CH16) — bringing 6½-digit precision to every point in the scan list. Factory-installed only: not a field upgrade.




Who it’s for & why
The SDM4065A-SC exists for the jobs where a logger is not accurate enough and a switching mainframe is too much: multi-channel calibration comparisons, long-duration reliability runs where microvolt-level drift matters, burn-in monitoring where four true current channels measure shunts directly. It is a rack of instruments condensed into one calibrated box — and between scan jobs it still works as a full 6½-digit digitizing bench meter. As with all -SC models, the scanner cannot be retrofitted, so this is the configuration to buy when precision multi-point work is on the roadmap.
