Keithley 2440 SourceMeter SMU Instrument
- 5A SourceMeter
- Sourcing Current: ± 10µA to ± 5A
- Sourcing Voltage: ± 200mV to ± 40V
- Power: 50W
For newer applications, Keithley recommends the 2460 and 2461 SMUs.
Keithley’s SourceMeter family is designed specifically for test applications that demand tightly coupled sourcing and measurement. All SourceMeter models provide precision voltage and current sourcing as well as measurement capabilities. Each SourceMeter instrument is both a highly stable DC power source and a true instrument-grade 51 ⁄2-digit multimeter. The power source characteristics include low noise, precision, and readback.
The multimeter capabilities include high repeatability and low noise. The result is a compact, single-channel, DC parametric tester. In operation, these instruments can act as a voltage source, a current source, a voltage meter, a current meter, and an ohmmeter. Manufacturers of components and modules for the communications, semiconductor, computer, automotive, and medical industries will find the SourceMeter instruments invaluable for a wide range of characterization and production test applications.
