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 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 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. The Model 2420 High Voltage SourceMeter is a 60W instrument designed to source and measure voltage from ±5µV (source) and ±1µV (measure) to ±60V and current from ±100pA to ±3A. Production test applications for the Model 2420 include resistors and resistor network devices that must be tested at higher current levels, thermistors, solar cells, batteries, and high current or medium power diodes, including switching and Schottky diodes. The Model 2420 is also suitable for IDDQ testing of CMOS integrated circuits and monitoring the current consumption of battery-powered medical devices such as pacemakers.
