2401 Keithley Sourcemeter
The 2401 is a 20 watt Sourcemeter from Keithley. Source meter instruments are a type of electronic test equipment that measures and logs precise voltage and current data. Source meters collect information with high accuracy, ideal for current-voltage (I-V) characterization, semiconductor testing, and testing devices with both positive and negative current source values.

The Keithley 2401 offers users all the same accuracy, speed, and measurement functions as the rest of the instruments in the Series 2400 family. It shares a common operating code base with the rest of the family, so it can be operated and programmed within its range boundaries just like any other Series 2400 instrument. The only functional differences between the Model 2401 and the Model 2400 are that the Model 2401 does not include 200V source and measure ranges or back panel DigitalI/O port capabilities.
Advantages of a Tightly Integrated Instrument
By linking source and measurement circuitry in a single unit, these instruments offer a variety of advantages over systems configured with separate source and measurement instruments. For example, they minimize the time required for test station development, setup, and maintenance, while lowering the overall cost of system ownership. They simplify the test process itself by eliminating many of the complex synchronization and connection issues associated with using multiple instruments. And, their compact half-rack size conserves precious “real estate” in the test rack or bench.
Power of Five Instruments in One (IV Source, IVR Measure)
The tightly coupled nature of a SourceMeter instrument provides many advantages over separate instruments. For example, it provides faster test times by reducing GPIB traffic and simplifies the remote programming interface. It also protects the device under test from damage due to accidental overloads, thermal runaway, etc. Both the current and voltage source are programmable with readback to help maximize device measurement integrity. If the readback reaches a programmed compliance limit, then the source is clamped at the limit, providing fault protection.
All SourceMeter instruments provide four-quadrant operation. In the first and third quadrants they operate as a source, delivering power to a load. In the second and fourth quadrants they operate as a sink, dissipating power internally. Voltage, current, and resistance can be measured during source or sink operation.
