Class Description

class atomiq.components.electronics.currentsource.CurrentSource(min_current=-inf, max_current=inf, default_ramp_steps=30, *args, **kwargs)

Bases: Component, Parametrizable

Current Source

This abstract class represents any device that can output a defined, controllable current.

Parameters:

• min_current (TFloat) -- The minimum current the device can output [A]

• max_current (TFloat) -- The maximum current the device can output [A]

• default_ramp_steps (TInt32) -- The default number of steps that this device should use if the current is ramped. This value is only used if no ramp_steps are given in the ramp_current() method.

A Parametrizable is an entity that can be controlled by one or more continuous parameter(s)

set_current(current)

Set the current delivered by the current source

Parameters:

current (artiq.compiler.types.TMono('float', OrderedDict())) -- Current in A

ramp_current(duration, current_end, current_start=nan, ramp_timestep=-1.0, ramp_steps=-1)

Ramp current over a given duration.

This method advances the timeline by duration

Parameters:

• duration (artiq.compiler.types.TMono('float', OrderedDict())) -- ramp duration [s]

• current_end (artiq.compiler.types.TMono('float', OrderedDict())) -- end current [A]

• current_start (artiq.compiler.types.TMono('float', OrderedDict())) -- initial current [A]. If not given, the ramp starts from the current operating current.

• ramp_timestep (artiq.compiler.types.TMono('float', OrderedDict()))

• ramp_steps (artiq.compiler.types.TMono('int', OrderedDict({'width': artiq.compiler.types.TValue(32)})))
