The Keysight U3606B integrates a 5½ digit digital multimeter and 30 W DC power supply into a single compact instrument. It powers devices under test while simultaneously measuring voltage, current, and resistance, eliminating the need for separate benchtop equipment. With 120,000 counts resolution, 0.025% DC voltage accuracy, and dual interfaces (USB 2.0 and GPIB), the U3606B serves education, commercial electronics, semiconductor development, sensor technology, and R&D environments.
Technical Specifications
The DMM section delivers 5½ digit resolution across 10 measurement functions. DC voltage measurement spans 19.9999 mV to 1000 V with 0.025% accuracy. DC current measurement supports four independent ranges: 1 A at 30 V, 100 mA at 30 V, 3 A at 8 V, and 3 A at 1000 mV. Resistance measurement employs 4-wire configuration with 0.001 mΩ resolution across 100 mΩ to 1000 Ω. The instrument also measures AC voltage, AC current, and capacitance, with 8 built-in math functions.
The integrated power supply delivers 30 W across the same voltage/current ranges as the DMM. Load regulation and line regulation both achieve 0.01% + 3 mV. Over Voltage Protection (OVP) and Over Current Protection (OCP) guard against fault conditions. A square-wave generator produces selectable frequencies to 4.8 kHz. Advanced functions include ramp and scan capability for multi-level DC bias testing with auto ramp/scan modes, plus remote sensing.
