3.2.2. qupulse.hardware.dacs

class AlazarCard(card, config: atsaverage.config.ScanlineConfiguration | None = None)

Bases: DAC

arm_program(program_name: str) → None

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

property buffer_strategy: BufferStrategy

property card: Any

clear() → None

Clears all registered programs.

property config

property current_config

delete_program(program_name: str) → None

Delete program from internal memory.

property mask_prototypes: Dict[str, Tuple[int, str]]

measure_program(channels: Iterable[str] | None = None) → Dict[str, ndarray]

Get all measurements at once and write them in a dictionary.

property record_size_factor: int

The total record size of each measurement gets extended to be a multiple of this. None means that the minimal value supported by the card is taken.

register_mask_for_channel(mask_id: str, hw_channel: int, mask_type='auto') → None

Parameters:

• mask_id – Identifier of the measurement windows

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

• mask_type – Either ‘auto’ or ‘periodical

register_measurement_windows(program_name: str, windows: Dict[str, Tuple[ndarray, 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.

set_measurement_mask(program_name, mask_name, begins, lengths) → Tuple[ndarray, 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)

class DAC

Bases: object

Representation of a data acquisition card

abstractmethod arm_program(program_name: str) → None

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

abstractmethod clear() → None

Clears all registered programs.

abstractmethod delete_program(program_name) → None

Delete program from internal memory.

abstractmethod measure_program(channels: Iterable[str]) → Dict[str, numpy.ndarray]

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

abstractmethod 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.

abstractmethod 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.

abstractmethod 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)
