Delay Calibration¶

class DelayCalibrationBase(device=None)[source]¶

Bases: Calibration, Serializable

Abstract base class for all delay calibration classes.

correct_receive_delay(signal)[source]¶

Apply the delay calibration to a received signal.

Parameters:: signal (Signal) – The signal to be corrected.
Return type:: Signal

Returns: The corrected signal.

correct_transmit_delay(signal)[source]¶

Apply the delay calibration to a transmitted signal.

Parameters:: signal (Signal) – The signal to be corrected.
Return type:: Signal
Returns:: The corrected signal.

abstract property delay: float¶: Expected transmit-receive delay in seconds.

hdf_group_name = 'delay_calibration'¶: Group name of the calibration in the HDF save file.

class DelayCalibration(delay, physical_device=None)[source]¶

Bases: DelayCalibrationBase

Static delay calibration

classmethod Deserialize(process)[source]¶

Deserialize an object’s state.

Objects cannot be deserialized directly, instead a Factory must be instructed to carry out the deserialization process.

Parameters:: process (DeserializationProcess) – The current stage of the deserialization process. This object is generated by the Factory and provides an interface to deserialization methods supporting multiple backends.
Return type:: DelayCalibration
Returns:: The deserialized object.

static Estimate(device, max_delay, num_iterations=10, wait=0.0)[source]¶

Estimate a physical device’s inherent transmit-receive delay.

Ideally, the transmit and receive channels of the device should be connected by a patch cable. WARNING: An attenuator element may be required! Be careful!!!!

Parameters:

device (PhysicalDevice) – The physical device to calibrate, i.e. the device of which a delay is to be estimated.
max_delay (float) – The maximum expected delay which the calibration should compensate for in seconds.
num_iterations (int) – Number of calibration iterations. Default is 10.
wait (float) – Idle time between iteration transmissions in seconds. Zero by default.

Return type:

DelayCalibration

Returns: An initialized delay calibration instance.

serialize(process)[source]¶

Serialize this object’s state.

Objects cannot be serialized directly, instead a Factory must be instructed to carry out the serialization process.

Parameters:: process (SerializationProcess) – The current stage of the serialization process. This object is generated by the Factory and provides an interface to serialization methods supporting multiple backends.
Return type:: None

property delay: float¶: Expected transmit-receive delay in seconds.

class NoDelayCalibration(device=None)[source]¶
