2013 R&D 100 Winner
Keithley Instruments' Model 2657A High Power System SourceMeter SMU InstrumentA drive toward greater energy efficiency is creating increased demand for more efficient high-power semiconductor devices. New materials technologies hold promise for these devices. However, with the improved performance of these devices, characterization and measurements are becoming more complex due to the extreme and conflicting demands of higher voltage, higher power and lower current resolution. Keithley Instrument’s Model 2657A High Power System SourceMeter SMU Instrument is a high-voltage (±3 kV), high-power (180 W), low-current (1 fA) source measure unit (SMU) designed to enhance precision, speed, flexibility and ease-of-use in R&D and test environments. Because it combines a highly flexible, four-quadrant voltage and current source/load with precision voltage and current meters, the SMU can source or sink up to 3,000 V @ 20 mA or 1,500 V @ 120 mA. It can be used as a semiconductor characterization instrument, arbitrary waveform generator, voltage or current pulse generator, precision power supply with voltage and current readback, a true current source, a digital multimeter and a precision (18-bit) electronic load.
