The ki_6487 module

Module for Keithley 6487 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_6487, manages its picoammeter capabilities.

API

cmd_ki_6487.init_ki_6487(ki_6487_id, conf_string)
