WAV / IQ Viewer
Inspect recorded signals
What it does
SimpleAfter you record a signal, this shows it as a wiggly line or a picture so you can *see* its shape with your eyes — where it beeps, how long each pulse is, and how the pieces fit together.
It's how you 'read' a recording. Many signals give up their secrets just by looking at their shape: you can often measure the pulses and work out the pattern of 1s and 0s by hand.
How it works
SimpleThe app draws the recording so tall parts mean 'signal on' and flat parts mean 'off'. By measuring how long the ons and offs are, you can tell dots from dashes, or 1s from 0s — like reading a heartbeat monitor for radio.
How to use it, step by step
Simple- Record something first with Capture.
- Open the 'WAV/IQ Viewer' and pick the file.
- Look at the shape of the signal.
- Measure the pulses to figure out the pattern.
Examples
Measure pulse widths in a captured OOK burst to work out its bit pattern.
Spot the repeated preamble/sync at the start of a packet in the waveform.
Use the spectrogram to see how wide a signal is and whether your capture bandwidth was enough.
Tips & things to try
- Simple OOK signals can often be read straight off the timing — no decoder needed.
- If a signal looks cut off in the spectrogram, your capture bandwidth was too narrow.
- It's the bridge between capturing a signal and actually understanding it.
