Classes

AlazarCard(atsaverage_card)

class qupulse.hardware.dacs.alazar2.AlazarCard(atsaverage_card: atsaverage.core.AlazarCard)

Bases: qupulse.hardware.dacs.dac_base.DAC

arm_program(program_name: str) → None

Prepare the device for measuring the given program and wait for a trigger event.

property atsaverage_card

clear() → None

Clears all registered programs.

property current_sample_rate_in_giga_herz: qupulse.utils.types.TimeType

delete_program(program_name: str) → None

Delete program from internal memory.

get_current_input_range(channel: Union[str, int])

measure_program(channels: Optional[Iterable[str]] = None) → Dict[str, numpy.ndarray]

Get the last measurement’s results of the specified operations/channels

register_mask_for_channel(mask_id: str, hw_channel: int) → None

Parameters

• mask_id – Identifier of the measurement windows

• hw_channel – Associated hardware channel (0, 1, 2, 3)

register_measurement_windows(program_name: str, windows: Dict[str, Tuple[numpy.ndarray, numpy.ndarray]]) → None

Register measurement windows for a given program. Overwrites previously defined measurement windows for this program.

Parameters

• program_name – Name of the program

• windows – Measurement windows by name. First array are the start points of measurement windows in nanoseconds. Second array are the corresponding measurement window’s lengths in nanoseconds.

register_operations(program_name: str, operations) → None

Register operations that are to be applied to the measurement results.

Parameters

• program_name – Name of the program

• operations – DAC specific instructions what to do with the data recorded by the device.

property registered_programs: Mapping[str, qupulse.hardware.dacs.alazar.AlazarProgram]

set_measurement_mask(program_name: str, mask_name: str, begins: numpy.ndarray, lengths: numpy.ndarray) → Tuple[numpy.ndarray, numpy.ndarray]

Set/overwrite a single the measurement mask for a program. Begins and lengths are in nanoseconds.

Parameters

• program_name – Name of the program

• mask_name – Name of the mask/measurement windows

• begins – Staring points in nanoseconds

• lengths – Lengths in nanoseconds

Returns

Measurement windows in DAC samples (begins, lengths)
