Keithley 2601B System Source Measure Unit SMU

If you’re diving into semiconductor testing, circuit design, or precision hardware engineering, the Keithley 2601B is about to become your favorite bench companion. Part of the legendary 2600B Series, this isn`t just a power supply—it’s a Source Measure Unit (SMU).

Think of it as the "Swiss Army Knife" of the electronics lab. It combines the capabilities of a precision power supply, a true current source, a 6½-digit DMM, an arbitrary waveform generator, and an electronic load into one sleek box.

The 2601B is designed for I-V characterization. It can simultaneously "source" (apply) voltage or current while "measuring" the resulting current or voltage with insane accuracy.
