The Keithley 2401 Low Voltage SourceMeter provides precision voltage and cur sourcing and measurement capabilities (1µV – 20V and 10pA – 1A). It is both a highly stable DC power source and a true instrument-grade 5½-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.Features and Specifications of the Keithley 2401 Low Voltage SourceMeter Instrument include:
Five instruments in one:
- Voltage source
- Cur source
- Voltage meter
- Cur meter
- Ohmmeter
Source and sink (4-quadrant) operation
0.012% basic measure accuracy with 5½-digit resolution
2-, 4-, and 6-wire remote V-source and measure sensing
1700 readings/second at 4½ digits via GPIB
