SMU INSTRUMENTS
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 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 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
• V or I waveform generator
• V or I pulse generator
• Precision power supply with V and I readback
• Digital multimeter (DCV, DCI, ohms, and
power with 6½-digit resolution)
• Precision electronic load
• True current source

Two Measurement Modes: Digitizing or Integrating
Precisely characterize transient and steady-state behavior, including rapidly changing thermal effects,
with the two measurement modes in the Model 2657A. Each mode is defined by its independent
analog-to-digital (A/D) converters.
The digitizing measurement mode provides speeds up to 1µs per sample. The dual 18-bit digitizers
allow you to capture voltage and current transients simultaneously. In the integrating measurement
mode, the dual 22-bit integrating analog to digital converters allow more precise measurement of voltage and current. Two A/D converters are used with each measurement mode, one for current and
the other for voltage, that run simultaneously for accurate source readback that does not sacrifice
test throughput.

Expansion Capabilities
Through TSP-Link Technology technology, the Model 2657A can be linked with Series 2600B SMU
instruments to form a larger integrated system with up to 32 nodes. Precision timing and tight channel synchronization are guaranteed with built-in 500ns trigger controllers. The fully isolated, independent channels of the SourceMeter SMU instruments make true SMU-per-pin testing possible.
High Power Device Test Fixture
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 SMU instrument (Model 2657A), one or two high current SourceMeter SMU
instruments (Model 2651A), and three low power SourceMeter SMU instruments (Series 2600B or
Model 4200-SCS SMU instruments). This allows devices with two terminals (diodes) or three terminals (transistors) or even four or five terminals to be characterized safely and accurately. The Model
8010 has full interlock capability for up to six SourceMeter SMU instruments. The Model 8010 has
integrated protection circuits that protect the low voltage SourceMeter SMU instruments from high
voltages the Model 2657A can output should a device fault occur. The Model 8010 includes both a
high current (100A) and a high voltage (3000V) test socket. Various replacement test socket modules
are available, including TO-247, TO-220, axial lead, and a blank socket module that allows building
a custom socket. In addition to standard banana jumpers, the Model 8010 has rear-panel scope and
thermal probe ports to simplify system integration.
