The ki_6517 module

Module for Keithley 6517 voltage source. Compatible with the ps module.

Note

The support for this device is divided in two modules. The present one manages its voltage source, while the second, cmd_mm_ki_6517, manages its picoammeter capabilities.

API

cmd_ki_6517.init_ki_6517(ki_6517_id, conf_string)

Initialize ki_6517 power supply identified by ki_6517_id.

conf_string must include the parameter:
