2-Channel SourceMeter, 1fA, 200V, 1.5A DC / 10A Pulse, Bench Top Version. The Keithley 2634B is a SourceMeter and a dual-channel SMU Instrument with best-in-class value and performance. Its tightly-integrated, four-quadrant design allows it to simultaneously source and measure both voltage and current to boost productivity in R&D and bench-top applications. The wide range of 1.5 A DC, 10 A pulse, 200 V output and 1 fA measurement resolution makes it suitable to test a wide range of lower current devices and materials. The 2634B is equipped with Keithley's high speed TSP technology, which is over 190% faster than traditional PC-to-instrument communication techniques. It is designed for bench-top applications and, therefore, does not have the high-end, system-level automation features of the Model 2636B SourceMeter SMU Instrument that includes digital I/O, TSP-Link technology, and contact check function. Source/Measure capabilities: Dual-channel model with 60 W power output (30 W/channel) 4 quadrant source/measure with 6½-digit resolution Current Max/Min: 1.5 A DC,10 A pulse/1 fA Voltage Max/Min: 200 V/100 nV General features: Compatibility with the Keithley IVy mobile app Built-in web browser based software for I-V characterization TSP (Test Script Processing) technology embeds complete test programs inside the instruments Software emulation for Keithley's Model 2400 SourceMeter SMU Instrument Large, easy-to-read, dual line display
