Procedure catalog

Built-in measurement procedures. For the class hierarchy and lifecycle see Procedures; to write your own see Creating a New Procedure.

Authoritative source

A procedure's exact INPUTS, DATA_COLUMNS and defaults live in its source file under laser_setup/procedures/ and may be overridden in procedures.yaml. The tables below summarize intent; check the source for the definitive list.

Parameter categories (parameters.yaml)

Most parameters come from shared categories. See Defining Parameters.

Category	Examples
Chip	chip_group, chip_number, sample
Laser	laser_toggle, laser_wl, laser_v, laser_T, burn_in_t, fiber, wl, wl_start/end/step
Instrument	Irange, Vrange, NPLC, N_avg, sense_T, sensor
Control	vds, vg, vg_dynamic, vg_toggle, sampling_t, step_time, vg_start/end/step, vsd_start/end/step, vl_start/end/step, initial_T, target_T, T_start_t, T_start/end/step, t_on, t_off

Common parameters (all procedures)

From BaseProcedure:

Parameter	Type	Default	Notes
procedure_version	Parameter	1.0.0	Versioning, often overridden in YAML.
show_more	Boolean	false	Reveals advanced (group_by: show_more) inputs.
info	Parameter	None	Free-text note saved to the file.
skip_startup	Boolean	false	Skip startup() (used by sequences).
skip_shutdown	Boolean	false	Skip shutdown().
start_time	Metadata	—	time.time() at run start.

ChipProcedure adds: chip_group, chip_number, sample.

Example: It inputs

A concrete reference (from procedures/It.py):

DATA_COLUMNS = ['t (s)', 'I (A)', 'VL (V)'] + PT100SerialSensor.DATA_COLUMNS
INPUTS = ChipProcedure.INPUTS + [
    'vds', 'Irange', 'vg_toggle', 'vg', 'laser_toggle', 'laser_wl', 'laser_v',
    'laser_T', 'sampling_t', 'sense_T', 'initial_T', 'target_T', 'T_start_t', 'NPLC',
]
EXCLUDE = ChipProcedure.EXCLUDE + ['vg_toggle', 'laser_toggle', 'sense_T']
SEQUENCER_INPUTS = ['vds', 'laser_v', 'vg', 'target_T']

Note vg accepts the dynamic expression DP + <delta> V (resolved by VgMixin); It runs a three-phase laser off→on→off cycle whose total length is laser_T × 3/2.

Per-procedure version overrides

procedures.yaml pins each procedure's procedure_version and tweaks a few defaults. See the template for the current values; e.g. It ships at 2.2.0 with laser_T: 120 s and vg: "DP + 0. V".
