Keysight U3606A Multimeter, DC Power Supply, 5½ Digit

The Keysight U3606A combines a 5½ digit digital multimeter with a 30 W DC power supply in a single benchtop instrument. Both functions operate simultaneously and independently, enabling efficient device testing and circuit development without sacrificing bench space. The DMM delivers 120,000 counts resolution with 0.025% basic DC voltage accuracy and up to 37 readings/second, while the power supply provides dual-range output (30 V / 1 A or 8 V / 3 A) with remote sensing and protection circuitry. This hybrid architecture suits component characterization, power circuit validation, and multi-parameter troubleshooting.
