Guided Configuration

Start from the executable's current template instead of copying an older experiment:

pmoke config init --output config.toml

Instrument endpoints

scope identifies the oscilloscope and its direct connection. generator identifies the trigger source and may use direct GPIB or a Prologix adapter.

version = 5

[scope]
model = "DHO5108"
connection = "tcp://192.0.2.10:55255"

[generator]
model = "WF1946B"
connection = "prologix-tcp://192.0.2.20:1234?addr=11"

Channel roles

Each sensor has exactly one scale form. The reference channel records the function-generator sine wave sent to the EOM in the zero-area Sagnac interferometer. Fitting this electrical signal determines the frequency and phase used by numerical lock-in analysis. Lock-in signal channels contain the photodetector response.

[[sensors]]
channel = 1
scale = { max_abs = 55.0, polarity = -1 }
label = '$\mu_0H$'
unit = "T"

[reference]
channel = 2
fft_window = { start = 0.0, end = 0.015 }

[lockin]
signal_channels = [3]
filter = { kind = "boxcar_legacy", half_window_cycles = 1.0 }

Artifact policy

Use RAW acquisition for large DHO captures. --run-dir isolates each shot and records immutable source and resolved configuration snapshots.

[data]
output = "raw"
input = "auto"
screenshot = true

Use the generated field reference for every default and constraint.
