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_start, current_end, ramp_timestep=- 1.0, ramp_steps=- 1)

Ramp current over a given duration.

This method advances the timeline by duration

Parameters:

duration (TFloat) -- ramp duration [s]
current_start (TFloat) -- initial current [V]
current_end (TFloat) -- end current [V]
ramp_timestep (TFloat) --
ramp_steps (TInt32) --

set_current(current)

Set the current delivered by the current source

Parameters:: current (TFloat) -- Current in A
