Application Examples

R&D and Product Development

Engineers developing precision analog circuits can rely on the SDM4055A for tracking minute voltage fluctuations, verifying noise performance, or validating sensor outputs under changing environmental conditions. With its data logging and math features, it’s easy to monitor behavior over time or run automated test routines.

Automated Production Testing

In manufacturing environments, the SDM4055A integrates easily into automated test setups using SCPI control. Combine the SDM4055A-SC version with a 16-channel scanner card to perform multi-point functional tests on assemblies or burn-in testing without manual intervention.

Repair and Calibration

Technicians and service engineers benefit from the SDM4055A's wide measurement range and dual display when repairing power supplies, calibrating instrumentation, or validating sensor outputs. Continuity and diode tests with audio feedback make it easier to trace circuit connections quickly.

Environmental and Thermal Testing

Test labs measuring temperature-dependent characteristics of components or circuits can use thermocouple and RTD inputs for precise readings. Built-in cold junction compensation and long logging intervals make it ideal for characterizing devices across temperature cycles.

Battery and Power Supply Analysis

Measure battery voltage drift, current draw, or ripple in AC power systems with precision. With trend chart and histogram modes, you can visualize transient behavior or changes over time without needing additional software.

The Siglent SDM4055A is an exceptional choice for professionals who need a dependable, accurate, and flexible multimeter for complex measurement tasks. With rich features packed into a sleek, compact form, it redefines what a benchtop DMM can offer.

Looking for automated testing or multi-channel measurements? Choose the SDM4055A-SC with the built-in scanner card for even more versatility. NOTE: The scanner is included on new SDM4055A-SC products only. It cannot be added to SDM4055A-SC instruments at a later time.
