- class ETH_awg_interface(awg_freq=1.5, dig_rate=2)¶
Bases:
autodeer.classes.InterfaceRepresents the interface for connecting to Andrin Doll style spectrometers.
An interface for connecting to a Andrin Doll style spectrometer, commonly in use at ETH Zürich.
- Parameters:
- awg_freqfloat
The normal operating AWG frequency. Sequence.LO = AWG.LO + AWG.awg_freq
- dig_ratefloat
The speed of the digitser in GSa/s
- property savefolder¶
- awg_freq¶
- dig_rate¶
- pulses¶
- cur_exp = 'None'¶
- bg_data = 'None'¶
- bg_thread = 'None'¶
- IFgain_options¶
- IFgain = '2'¶
- connect(session=None)¶
Connect to a running matlab session. If more than one session has been started this will choose the first one. It is recomended that only one session is open at one time, or that the engine is started with a known name.
- Parameters:
- sessionstr, optional
The string denoting a specific session to connect to , by default None
- acquire_dataset(verbosity=0)¶
Acquires the dataset.
- acquire_dataset_from_matlab(verbosity=0, **kwargs)¶
Acquire and return the current or most recent dataset.
- Returns:
- dict
The dataset
- launch(sequence, savename, *args, **kwargs)¶
Launches the experiment and initialises autosaving.
- Parameters:
- sequenceSequence
The sequence to be launched
- savenamestr
The savename for this measurement. A timestamp will be added to the value.
- launch_withIFGain(sequence, savename, IFgain=0)¶
Launch a sequence on the spectrometer.
- Parameters:
- sequenceSequence
The pulse sequence to launched.
- savenamestr
The save name for the file.
- IFgainint
The IF gain, either [0,1,2], default 0.
- launch_normal(sequence, savename, IFgain=0, reset_cur_exp=True)¶
- launch_long(sequence, savename, IFgain=0, axID=-1)¶
Launch a sequence on the spectrometer that is too long for a single file. This is to get around the issues with the sequence table by running a background loop that takes control.
current issues: - uses some bruker tools functions - only works for a single averages - creates many extra files
- Parameters:
- sequenceSequence
The pulse sequence to launched.
- savenamestr
The save name for the file.
- IFgainint
The IF gain, either [0,1,2], default 0.
- isrunning()¶
- tune_rectpulse(*, tp, LO, B, reptime, shots=400)¶
Generates a rectangular pi and pi/2 pulse of the given length at the given field position. This value is stored in the pulse cache.
- Parameters:
- tpfloat
Pulse length of pi/2 pulse in ns
- LOfloat
Central frequency of this pulse in GHz
- Bfloat
Magnetic B0 field position in Gauss
- reptime: float
Shot repetion time in us.
- shots: int
The number of shots
- Returns:
- p90: RectPulse
A tuned rectangular pi/2 pulse of length tp
- p180: RectPulse
A tuned rectangular pi pulse of length tp
- tune_pulse(pulse, mode, LO, B, reptime, shots=400)¶
Tunes a single pulse a range of methods.
- Parameters:
- pulsePulse
The Pulse object in need of tuning.
- modestr
The method to be used.
- LOfloat
The local oscilator frequency in GHz
- Bfloat
Magnetic B0 field position in Gauss
- reptimeus
Shot repetion time in us.
- shots: int
The number of shots
- Returns:
- Tunned Pulse: Pulse
The returned pulse object that is now tunned.
- tune(*, sequence=None, mode='amp_hahn', LO=None, gyro=None)¶
- _build_exp_struct(sequence)¶
- _build_pulse(pulse)¶
- _build_phase_cycle(sequence)¶
- _build_parvar(id, sequence)¶
This interface takes a dictionary called a parvar for all progressive elements. It is this object that controls how the sequence changes with time.
Note
This interface interprets any change in LO as being a change in the IF frequency of all pulses and detections.
I.e. the physcial LO does not change.
- Parameters:
- id_type_
_description_
- sequence_type_
_description_
- Returns:
- dict
_description_
- terminate()¶
Stops the current experiment
