Source Meter

The SourceMeter combines a precise, low-noise, highly stable DC power supply with a low-noise, highly repeatable, high-impedance multimeter.

It has 0.012% basic accuracy with 5½-digit resolution. At 5½ digits, the SourceMeter delivers 520 readings/second over the IEEE-488 bus. At 4½ digits, it can read up to 2000 readings/second into its internal buffer. The unit has broad source and measurement ranges:

Model 2401:

• Source voltage from 5μV to 210V; measure voltage from 1μV to 211V.

• Source current from 50pA to 1.05A; measure current from 10pA to 1.055A.

• Measure resistance from 100μΩ (<100μΩ in manual ohms) to 211MΩ.

• Maximum source power is 22W
