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
®
compliant for
easy system integration
with Series 2600B System
SourceMeter models
• Combines a precision power
supply, current source, DMM,
arbitrary waveform generator, V
or I pulse generator, electronic
18-bit load, and trigger controller
– all in one instrument
• Includes TSP
