Working with the Decoded Waveform
Serial Decode Annotations
When a decoder is enabled, an annotated waveform showing the decoder results appears on the
oscilloscope display.
A colored overlay marks significant transitions in the source signal. The overlay contains annotations
corresponding to the data itself, any pre/post-message padding, inter-burst periods, etc. Each set of
annotations is customized to the protocol or encoding scheme.
The information shown on a given annotation is affected by the width of the rectangles in the overlay,
which is determined by the magnification (scale) of the trace and the length of the acquisition. If the
rectangles are:

< 10 pixels wide, no annotation is shown.

> 10 but < 100 pixels wide, only the short form of the names appear.

> 100 but < 500 pixels wide, the long form name and number of repetition appears

> 500 pixels, all details appear.
These overlays appear on the source trace or its zoom trace to highlight key portions of the decoded
signal.

Inter Frame Gap - Green overlay indicating period between bursts.

Burst - Navy overlay indicating period of burst (data frame).

Synchro - Grey overlay to left of status showing synchronization timeout value.

Status - Bright purple overlay to left of data, showing status and communication bits.

Data - Bright aqua overlay, indicating payload data.
Decoded waveform. At this resolution, very little information appears on the overlay.
