Some template vars

Members: ESR_Measurement Functions: Classes:

A service for interfacing with the ESR

Summary

class dragonfly.implementations.esr_measurement.ESR_Measurement(**kwargs)

Bases: dragonfly.implementations.esr_measurement.ESR_Measurement

Operate the ESR system to measure the B-field off-axis. Methods are sorted by order of call within run_scan.

Keyword Arguments:  

• name (str) – unique identifier across all dripline services (used to determine routing key)
• calibration (str||dict) – string use to process raw get result (with .format(raw)) or a dict to use for the same purpose where raw must be a key
• get_on_set (bool) – flag to toggle running ‘on_get’ after each ‘on_set’

capture_settings()

Record current status of the insert, lockin, and sweeper before ESR scan FIXME: Endpoints should either be locked here or already

check_endpoint(endptname, val)

Sets endpoint to value

endptname (str): name of endpoint val (int,float,str,unicode): value of endpoint to set

configure_instruments()

Configure instruments to default settings.

handle_request(channel, method, properties, request)

is_locked

lock(lockout_key=None, *args, **kwargs)

lockout_key

on_cmd(*args, **kwargs)

WARNING! if you override this method, you must ensure you deal with lockout properly

on_config(attribute, value=None)

configure a property again

WARNING! if you override this method, you must ensure you deal with lockout properly

ping(*args, **kwargs)

ignore all details and respond with an empty message

pull_lockin_data(key)

Call grab_data method of lockin_interface give key

key (): #TODO_DOC

raw_get_endpoint(endptname, **kwargs)

Get raw value of endpoint

endptname (str): name of endpoint

reset_configure()

Immutable “safe” configuration for switches and sweeper for after ESR scan

run_scan(config_instruments=True, coils=[1, 2, 3, 4, 5], n_fits=2, **kwargs)

Wraps all ESR functionality into single method call with tunable arguments. This function should interface with run_scripting through the action_esr_run method.

config_instruments (bool): flag to configure instruments coils (list): list of coil numbers (int) for ESR scan n_fits (int): number of fits to perform

save_data()

Save data to output json file

set_condition(*args, **kwargs)

To actually do something inside a class, the set_condition should be implemented in the class itself.

single_measure(coil)

Communicate with lockin, sweeper, and switches to execute single ESR coil scan. Data is retrieved but not analyzed.

unlock(*args, **kwargs)
