Use when the user wants to know what signals are present — characterize a capture or a simulated device's spectrum (PSD, signal detection, spectrogram) and summarize what's on the air.

Use when the user wants to receive or demodulate a specific signal — build, validate, run, and verify a receiver pipeline, then save it as a reusable, GRC-openable flowgraph.
Use when a receiver runs but produces no output, noise, or the wrong result — systematically locate the fault instead of guessing, using render and measure to see the problem.
Use ONLY as a last resort when no Marconi tool or vocabulary block can express the task — write a Python script against the marconi library, run it, and report the capability gap.
Use when the user wants a test signal or a simulated RF environment with no hardware — translate intent into a scene and register it as a persistent simulated device.
Use when the user wants a closed-loop transmit-then-receive experiment in simulation — transmit a capture into a simulated device's scene and receive it back to confirm the link.

Characterize what's present in a capture, then summarize it for the user. This is the first step of almost every RF task ("what's here?").
capture(device_id, center_freq, sample_rate, duration). From a file the user brings: load_capture(path). Use the returned path for everything below.psd(capture_path) → noise floor + strongest peaks. find_signals(capture_path) → candidate signals (center_freq, bandwidth, snr_db).spectrogram(capture_path) and read the image. find_signals is a first pass over a 1-D PSD; the spectrogram shows time/frequency structure (bursts, drift, multiple carriers) that the list can miss. If you see on/off activity, run detect_bursts(capture_path) for structured burst timing (start, duration, power).measure. A wide signal (e.g. an FM carrier) with a low noise floor can fragment into several find_signals detections. For any wide or clustered group, call measure(capture_path, center_freq=...) to get the true 99% occupied bandwidth, and trust the spectrogram over the raw detection count.noise element (amplitude ≈ 0.005).measure result as a real signal only above ~8 dB SNR; below that you're likely measuring noise.measure when you need a real bandwidth number.
