The Keithley 2601B-PULSE is Keithley's source measure unit in the Model 2601B-PULSE System SourceMeter Instrument (10 µsec Pulser/SMU) family. Its SCPI remote-control interface exposes 15 commands across 2 subsystems - 8 settable and 7 queries - and every command is catalogued here by subsystem, with its query or setter form and the programming-manual page that documents it for automating test and measurement over SCPI.
