Keithley Instruments 2420 Overview

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. Keithley's SourceMeter family is designed specifically for test applications that demand tightly coupled, precision voltage and current sourcing and measurement. By acting as a V-Source, I-Source, V-Meter, I-Meter and ohmmeter, each Series 2400 instrument functions as compact, single-channel, DC parametric tester. These half-rack instruments are invaluable for a wide range of design and production applications because they conserve precious rack real estate, and lower the overall cost and complexity of using multiple instruments. Built-in math functionality can derive parameters and mathematical formulas. A digital I/O interface can speed up production testing by linking the 2400 to popular component handlers for tight systems integration in binning, sorting, and similar applications. Advanced features such as 6-wire ohms measurement and guarding expand the versatility of the 2400 Series to handle production testing of a wide range of resistive devices The 2400 line features Keithley's unique Trigger-Link interface for seamless integration of Series 7000 switching hardware to produce complete, multipoint test solutions. The optional Contact Check function verifies test connections easily in just 350µs to maximize test integrity.
