Model 2651A SourceMeter instrument reportedly provides the widest current range available for testing high brightness LEDs, power semiconductors, DC-DC converters, batteries, and other high power materials, components, modules and subassemblies. Offers a four-quadrant voltage and current source/load coupled with precision voltage and current meters. Combines functionality of multiple instruments in a single full-rack enclosure: semiconductor characterization instrument, precision power supply, current source, DMM, arbitrary waveform generator, V or I pulse generator, electronic load and trigger controller. Is expandable into a multi-channel synchronized system via TSP-Link technology. Can source or sink up to 2,000W of pulsed power (±40V, ±50A) or 200W of DC power (±10V@±20A, ±20V@±10A, ±40V@±5A). Measures signals as low as 1pA and 100 mV at speeds up to one microsec. per reading. Provides a choice of digitizing or integrating measurement modes for characterization of transient and steady-state behavior. TSP Express LXI-based I-V test software is embedded.
