Synthesis and Local Capture

Create an Example Signal Problem

workflow

Dataset Preparation

Create or capture RF examples, track them in the Library, then curate and inspect the dataset.

1. Synthesize or capture Generate examples or collect local RF captures for the problem.
2. Track in Library Store large recordings and datasets with Git LFS-backed Library metadata.
3. Curator Filter, select, slice, and label the candidate examples.
4. Inspector Check balance, stats, recommendations, and per-class controls.

generator

Synthetic generation

Use this when you need repeatable training data, quick examples, or a known class distribution.

Synthetic generation is useful for controlled examples and quick training material. Local capture is useful when the task depends on hardware, environment, device behavior, or scenario-specific interference. In both cases, the output should enter the Library before curation.

SNR sample distribution

A compact meter for expected signal quality in generated examples.

• Median SNR

Series	Preview
Median SNR	18 dB

Generator Settings

Generator settings to document

Modulation selection

Choose the modulation classes that match the training problem.

SNR range

Set expected signal quality and keep enough variation for the model to generalize.

Signal configuration

Record sample rate, center frequency assumptions, pulse shaping, channel model, and gain settings.

Estimated totals

Confirm generated examples, class counts, and storage size before starting the task.

Next steps

• Create recordings with the CLI — Creating Recordings covers ria synth and ria capture for producing SigMF files and pushing them to a repository.
• Curate the data — Once recordings are in the Library, continue to Curation and Labeling.
