High Power System SourceMeter® Instrument
Keithley Model 2657A is a high voltage, high power, low current source measurement unit (SMU) instrument that delivers unprecedented power, precision, speed, flexibility, and ease of use to improve productivity 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 joins Keithley's Series 2600A family of power semiconductor characterization and test solutions to offer the highest power and best low current performance in the industry. These custom-configurable solutions are supported by the industry's most powerful parametric characterization software platforms to grow with you as your applications evolve.

The Model 2657A, like every Series 2600A SourceMeter instrument, offers a 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
• V or I waveform generator
• V or I pulse generator
• Precision power supply with V and I readback
• True current source
• Digital multimeter (DCV, DCI, ohms, and power with 6-1/2 digit resolution)
• Precision electronic load

High Power Device Test Fixture Available
The Model 8010 High Power Device Test Fixture provides safe and easy connections for testing packaged high power devices at up to 3000V or 100A. The Model 8010 provides connections for a high voltage SourceMeter instrument (Model 2657A), one or two high current SourceMeter instruments (Model 2651A), and three low power SourceMeter instruments (other Series 2600A or Model 4200-SCS SMU instruments).

Includes: 7709-308A Digital I/O and Interlock Connector, CA-180-3A TSP-Link/Ethernet Cable, Documentation CD, and Software tools and drivers CD.
