Class Description

class atomiq.components.electronics.currentsource.RPCCurrentSourceChannel(rpc_currentsource, channel, *args, **kwargs)

Bases: CurrentSource

One channel of a multi-channel currentsource controlled via RPC

Parameters:

• rpc_currentsource (Component) -- The ARTIQ rpc object representing the multi channel current source. This object needs to provide a function named set_current(current_in_A, channel) to set the current.

• channel (TInt32) -- channel of the multi-channel current source to operate on

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

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))])))

set_current(current)

Set the current delivered by the current source

Parameters:

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