Keithley 2440-C-C SOURCEMETERThe Keithley 2440-C SourceMeter is designed specifically for test applications that demand tightly coupled sourcing and measurement. It provides precision voltage and cur sourcing as well as measurement capabilities. The Keithley 2440-C SourceMeter is both a highly stable DC power source and a true instrument-grade 5-1/2 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 cur source, a voltage meter, a cur meter, and an ohmmeter. Manufacturers of components and modules for the communications, semiconductor, computer, automotive, and medical industries will find the source-measure instruments invaluable for a wide range of characterization and production test applications.The dynamic range and functionality of the Keithley 2440-C SourceMeter makes it ideal for your applications such as testing high power pump lasers for use in optical amplifiers, laser bar testers, and testing other higher power components. The Keithley 2440-C SourceMeter’s 5A source and measure capability also extends the range of the Keithley L-I-V Test System. Manufacturers of pump laser modules, optical amplifiers, and computer, automotive, and consumer electronics products will find it invaluable for a wide range of design and production test applications.The Contact Check function makes it simple to maximize test integrity by verifying test connections easily in just 350µs before an automated test sequence begins. This eliminates measurement errors and false product failures associated with contact fatigue, breakage, contamination, loose or broken connection, relay failures, etc. Features and Specifications of the Keithley 2440-C SourceMeter include:
