A Greater Measure of Confidence

2657a

High Power System SourceMeter

®

SMU Instrument

The Model 2657A is a high voltage, high power, low current source measure unit (SMU) instrument

that delivers unprecedented power, precision, speed, flexibility, and ease of use to improve produc-

tivity in R&D, production test, and reliability environments . The Model 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 . The Model 2657A offers the highest power

and best low current performance in the industry . It is supported by the industry’s most powerful

parametric characterization software platforms to grow with you as your applications evolve .
The Model 2657A offers highly flexible, four-quadrant voltage and current source/load coupled with

precision voltage and current meters . It can be used as a:
• Semiconductor characterization instrument

source or sink up to 180W of DC

or pulsed power (±3000V@20ma,

±1500V@120ma)

1fa low current resolution

Dual 22-bit precision aDCs

and dual 18-bit 1µs per point

digitizers for high accuracy and

high speed transient capture

fully TsP
