Numbers	A custom qcodes Numbers validator that allows for nan values.
_Durations	Validator used for durations. It allows all numbers greater than or equal to 0.
_Amplitudes	Validator used for amplitudes. It allows all numbers and nan.
_NonNegativeFrequencies	Validator used for frequencies. It allows positive numbers and nan.
_Delays	Validator used for delays. It allows all numbers.
_Hashable	Validator used for hashables.

class Numbers(min_value: qcodes.validators.validators.numbertypes = -np.inf, max_value: qcodes.validators.validators.numbertypes = np.inf, allow_nan: bool = False)

Bases: qcodes.utils.validators.Numbers

A custom qcodes Numbers validator that allows for nan values.

Requires a number of type int, float, numpy.integer or numpy.floating.

Parameters:

• min_value – Minimal value allowed, default -inf.

• max_value – Maximal value allowed, default inf.

• allow_nan – if nan values are allowed, default False.

Raises:

TypeError – If min or max value not a number. Or if min_value is: larger than the max_value.

_allow_nan = False

validate(value: qcodes.validators.validators.numbertypes, context: str = '') → None

Validate if number else raises error.

Parameters:

• value – A number.

• context – Context for validation.

Raises:

• TypeError – If not int or float.:

• ValueError – If number is not between the min and the max value.:

class _Durations

Bases: Numbers

Validator used for durations. It allows all numbers greater than or equal to 0.

class _Amplitudes

Bases: Numbers

Validator used for amplitudes. It allows all numbers and nan.

class _NonNegativeFrequencies

Bases: Numbers

Validator used for frequencies. It allows positive numbers and nan.

class _Delays

Bases: Numbers

Validator used for delays. It allows all numbers.

class _Hashable

Bases: qcodes.utils.validators.Validator[Hashable]

Validator used for hashables.

_valid_values = (0, 'str')

validate(value: Hashable, context: str = '') → None

Validates if hashable else raises error.

Parameters:

• value – Value to validate

• context – Context for validation.

Raises:

TypeError – If value is not hashable.
