Class Description

class atomiq.components.electronics.voltagesource.DACChannel(dac_device, channel, *args, **kwargs)

Bases: VoltageSource

A single channel of a (possibly multichannel) DAC

A single channel of a DAC is a digitally controlled voltage source. Thus, this class inherits from VoltageSource.

Parameters:

• dac_device (DAC) -- the DAC the channel belongs to

• channel (TInt32) -- the number of the channel

ramp_voltage(duration, voltage_start, voltage_end, ramp_timestep=-1.0, ramp_steps=-1)

Ramp voltage over a given duration.

This method advances the timeline by duration

Parameters:

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

• voltage_start (artiq.compiler.types.TMono('float', OrderedDict())) -- initial voltage [V]

• voltage_end (artiq.compiler.types.TMono('float', OrderedDict())) -- end voltage [V]

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

• ramp_steps (artiq.compiler.types.TMono('int', OrderedDict([('width', artiq.compiler.types.TValue(32))])))

set_voltage(voltage)

Set the voltage delivered by the voltage source

Parameters:

voltage (artiq.compiler.types.TMono('float', OrderedDict())) -- Voltage in V
