atomiq.components.dummies module

Dummies

This module gathers differnt dummy components that mimic hardware but do nothing. They are mainly used for debugging atomiq

class atomiq.components.dummies.DummyADC(return_value, *args, **kwargs)

Bases: ADC

A Measurable has one ore more channels at which data can be measured

Parameters:

return_value (TFloat)

kernel_invariants = {'return_value'}

measure(samples=1, channel='')

Measures all channels and returns the mean for a given number of subsequent samples.

This method advances the timeline by samples * sampling_time

Parameters:

• samples (artiq.compiler.types.TMono('int', OrderedDict({'width': artiq.compiler.types.TValue(32)}))) -- number of samples to take and average

• channel (artiq.compiler.types.TMono('str', OrderedDict()))

Return type:

artiq.compiler.types.TMono('array', OrderedDict({'elt': artiq.compiler.types.TMono('float', OrderedDict()), 'num_dims': artiq.compiler.types.TValue(1)}))

Bases: RFSource

A dummy RFSource used for debugging

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

Parameters:

• default_frequency (TFloat)

• default_amplitude (TFloat)

• default_phase (TFloat)

• freq_limit (tuple)

• amp_limit (tuple)

• blind (TBool)

• default_ramp_steps (TInt32)

Play Arbitrary Samples from a List

This method allows to set the output amplitude, frequency an phase according to the values specified in respective lists. The whole sequence is played in the specified duration. The pattern store in the sample list can also be repeated.

We supports a scheme to prepare the arb function before it is actually used. If that is needed, run this function with prepapre_only = True when the arb should be prepared and with run_only = True when the prepared arb should be played. In both calls the other parameters have to be passed.

Parameters:

• samples_amp (artiq.compiler.types.TMono('list', OrderedDict({'elt': artiq.compiler.types.TMono('float', OrderedDict())}))) -- List of amplitude samples. If this list is empty (default), the amplitude is not modified.

• samples_freq (artiq.compiler.types.TMono('list', OrderedDict({'elt': artiq.compiler.types.TMono('float', OrderedDict())}))) -- List of frequency samples. If this list is empty (default), the frequency is not modified.

• samples_phase (artiq.compiler.types.TMono('list', OrderedDict({'elt': artiq.compiler.types.TMono('float', OrderedDict())}))) -- List of phase samples. If this list is empty (default), the phase is not modified.

• duration (artiq.compiler.types.TMono('float', OrderedDict())) -- The time in which the whole sequence of samples should be played back [s].

• repetitions (artiq.compiler.types.TMono('int', OrderedDict({'width': artiq.compiler.types.TValue(32)}))) -- Number of times the sequence of all samples should be played. (default 1)

• prepare_only (artiq.compiler.types.TMono('bool', OrderedDict()))

• run_prepared (artiq.compiler.types.TMono('bool', OrderedDict()))

ramp(duration, frequency_start=-1.0, frequency_end=-1.0, amplitude_start=-1.0, amplitude_end=-1.0, ramp_timestep=-1.0, ramp_steps=-1)

Ramp frequency and amplitude over a given duration. Parameters default to -1 to indicate no change. If the start frequency/amplitude is set to -1, the ramp starts from the last frequency/amplitude which was set. This method advances the timeline by ´duration´

Parameters:

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

• frequency_start (artiq.compiler.types.TMono('float', OrderedDict())) -- initial frequency [Hz]

• frequency_end (artiq.compiler.types.TMono('float', OrderedDict())) -- end frequency [Hz]

• amplitude_start (artiq.compiler.types.TMono('float', OrderedDict())) -- initial amplitude [0..1]

• amplitude_end (artiq.compiler.types.TMono('float', OrderedDict())) -- end amplitude [0..1]

• ramp_timesteps -- time between steps in the ramp [s]

• ramp_steps (artiq.compiler.types.TMono('int', OrderedDict({'width': artiq.compiler.types.TValue(32)}))) -- number of steps the whole ramp should have. This takes precedence over ramp_timesteps

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

set(frequency=-1.0, amplitude=-1.0, phase=0.0)

Set the frequency and amplitude. Frequency/amplitude are set to the last known value if -1 is given.

Parameters:

• frequency (artiq.compiler.types.TMono('float', OrderedDict())) -- frequency [Hz]

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

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