Keithley 236 Description:

The 236 Source-Measure Unit is a fully programmable instrument, capable of sourcing and measuring voltage or current simultaneously.

The 236 is really four instruments in one: voltage source, current source, voltage measure, and current measure. Creating custom sweeps of voltage or current is facilitated by the use of three waveform operations: CREATE, APPEND, and MODIFY.

These allow the user to select waveform parameters, combine multiple waveforms, and select and change any points in a waveform previously created or appended.
