High Power System SourceMeter Instrument, 1-Channel, w/ 2000W Pulsed Power, 200W DC Power, up to 50A at 40V, w/ pA and uV Resolution. Unit sold with a valid calibration certificate. The Keithley 2651A is a High Power System SourceMeter Instrument and designed to characterize and test high current and high power electronics. The wide dynamic range of 50 A, 40 V, 100 fA of this SMU instrument improves the productivity in applications across the R&D, reliability, and production spectrums. Through the TSP-Link interface and embedded Plug & Play" web software, the model 2651A can be combined with another 2651A to increase the maximum current range to 100A, with other Series 2600B SourceMeters to create SMU-per-pin test systems, or with the Model 2657A to create high power test systems capable of 3000 V and 100 A. Optional test fixtures and system-level accessories are also available. Source/Measure capabilities: Single channel model with 2000 W pulsed or 200 W DC power output 4 quadrant source/measure capability with 6½ digit resolution Current max./min.: 20 A DC, 50 A Pulse/100 fA Voltage max./min.: 40 V/ 100 nV General features: 1 µs/point, dual 18 bit digitizers for accurately characterizing transient behavior Built-in "Plug & Play" Java-based I-V characterization and test software TSP (Test Script Processing) technology embeds complete test programs inside the instruments TSP-Link expansion technology for multi-channel parallel test Large, easy-to-read dual-line display"
