2-Channel SourceMeter, 0.1fA, 200V, 1.5A DC / 10A Pulse. The Keithley 2636B is a SourceMeter and a improved two-channel SMU instrument with a tightly integrated four-quadrant design that allows it to simultaneously source and measure both voltage and current. The wide range of 1.5 A DC, 10 A pulse, 200 V, and 0.1 fA measurement resolution output makes it ideal to test a wide range of lower current devices and materials. Furthermore it offers 6½-digit resolution, USB 2.0 connectivity, and software command emulation of the Model 2400 SourceMeter SMU Instrument that enables easy migration of legacy test code and is equipped with Keithley's high speed TSP technology (over 190% faster than traditional PC-to-instrument communication techniques,) which dramatically improves the system-level speed to lower the cost of test. The TSP-Link interface enables multi-channel parallel test and expands the test system without the cost of a mainframe.
