Product Overview

The 2657A from Keithley is a high power system SourceMeter® SMU instrument. This high voltage, high power, low current source measure unit (SMU) delivers unprecedented power, precision, speed, flexibility and ease of use to improve productivity in R&D, production test and reliability environments. It combines a precision power supply, current source, DMM, arbitrary waveform generator, V or I pulse generator, electronic load and trigger controller all in one instrument. The 2657A is designed specifically for characterizing and testing high voltage electronics and power semiconductors such as diodes, FETs and IGBTs as well as other components and materials in which high voltage, fast response and precise measurements of voltage and current are required. It offers highest power and best low current performance in industry. The model 2657A offers highly flexible, four-quadrant voltage and current source/load coupled with precision voltage and current meters.
