21 | OOK decodes On-off keying based remote control protocols. | |
22 | ||
23 | It is aimed at 433MHz but should also work with other common RC frequencies. | |
24 | The input can be captured directly from a transmitter (before the modulation | |
25 | stage) or demodulated by an RF receiver. | |
26 | ||
27 | Over the air captured traces will be a lot noisier and will probably need the | |
28 | area of interest to be zoomed onto, then selected with the "Cursors" and the | |
29 | "Save Selected Range As" feature to be used to extract it from the noise. | |
30 | ||
31 | There is a limited amount of pre-filtering and garbage removal built into the | |
32 | decoder which can sometimes extract signals directly from a larger over the air | |
33 | trace. It depends heavily on your environment. | |
