The Keithley Model 2606B System SourceMeter instrument packs four 20-watt SMU channels into a single 1U form factor chassis. Targeting the fast-growing 3D sensing manufacturing industry, the rackspace-saving Model 2606B combines the capabilities of a precision power supply, true current source, 6½-digit DMM, arbitrary waveform generator, and pulse generator into one tightly integrated instrument. With its patented series ranging topology, the Model 2606B delivers up to 20,000 operations per second resulting from faster and smoother range changes and outputs that settle more quickly.
