Details
Reading this attribute returns the overvoltage protection limit that the SMU is presently using.
Setting this attribute to zero disables overvoltage protection (OVP).
When this attribute is set to a nonzero value, the SMU limits the voltage on the force leads to the value specified
by this attribute.
Setting the OVP limit to a value outside of the
limit
range generates error code
−
224, "Illegal parameter value."
Example
smua.source.protectv = 300
Limits voltage on SMU channel A to 300 V.
