From the project
DIY source-measure unit
Parameters: + Voltage ranges 12V and 120V (bipolar) + Current ranges 1uA, 10uA, 100uA, 1mA, 10mA, 100mA (bipolar) + Minimal set voltage step - 1mV + Minimal set current step - 100pA + Voltage resolution - 100uV + Current resolution - 1pA
JSMU is designed to work as standalone device, but can be connected to computer via USB, and controlled via simple commands in SCPI form, similar to Keithley 2xxx series SMUs.
