Class Description

class atomiq.components.sinara.sampler.Sampler(sampler_device, default_gain=[0, 0, 0, 0, 0, 0, 0, 0], *args, **kwargs)

Bases: ADC

Sinara Sampler 8 Channel ADC

This class represents the Sinara Sampler with all its 8 channels. It allows to sample all channels at once and to read out the result.

Parameters:

• sampler_device -- The ARTIQ device for the sampler from the device_db, e.g. @sampler0

• default_gain (TList(TInt32)) -- List with 8 entries setting the default gain for the 8 channels at startup. (default [0, .. , 0])

A Sampler card with all 8 channels.

Parameters:

• sampler_device -- ARTIQ sampler device from the device db

• default_gain (TList(TInt32)) -- (list(int)) default gain (0: 1, ..., 3: 1000) for the 8 channels

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)}))
