class qupulse.hardware.dacs.dac_base.DAC

Bases: object

Representation of a data acquisition card

abstract arm_program(program_name: str) → None

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

abstract clear() → None

Clears all registered programs.

abstract delete_program(program_name) → None

Delete program from internal memory.

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

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

abstract 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.

abstract 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.

abstract 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)
