exception nibcq.errors.SMUParameterError(message: str = 'SMU Parameters are set incorrectly.')

Bases: BCQError

Exception raised when some parameter related to the SMU is incorrect.

These, for example, can show that voltage or current limits are incorrect or exceeded or that some pre-required steps are not done yet on the SMU’s workflow.

Parameters:

message (str, optional) – Custom error message. Defaults to a standard message.

Examples

The following are examples of how this error can be raised:

• General: Incorrect Parameter

  >>> raise SMUParameterError("SMU Parameters are set incorrectly.")
  

• Specific: Measurement not finished before wanting to access it

  >>> raise SMUParameterError("SMU Measurement is not available.")
  

• Specific: Voltage limit exceeded

  >>> raise SMUParameterError(
  >>>     f"Voltage limit {voltage_limit_hi} V exceeds
  >>>     the allowed maximum of {max_voltage} V."
  >>> )
