The Keithley 2400 Digital Source Meter is a single-channel instrument that integrates voltage source, current source, voltage meter, current meter, and ohmmeter functionality into one unit. It delivers four-quadrant operation—sourcing and sinking power—with 0.012% basic measurement accuracy and 6½-digit resolution across coupled voltage and current sourcing and measurement. Maximum output is 20 W, with measurement speeds to 1700 readings per second at 4½ digits via GPIB. Built-in pass/fail comparator, linear/logarithmic/custom sweep capabilities, and support for 2-, 4-, and 6-wire sensing make it suited for DC parametric characterization in semiconductor, communications, computer, automotive, and medical applications.
