Data Decode

Overview

An oscilloscope feature, this displays both the electrical properties of a signal as well as the data encoded within the signal.

Challenges

Quickly navigating and searching through very long signals
Flexible configuration without excessive setup or clutter
Understanding how engineers create homegrown tweaks to data transmission standards

My Contributions

User needs research
Usability tests: planned, conducted, analyzed results
Designed mock-ups and prototypes
Invented new control for data input

Raw signal (yellow) is displayed alongside the decoded signal (purple).

Data can also be viewed in a table.

The table navigates through long data streams: Selecting a data packet in the table displays the corresponding area of the raw signal.

Search lets the engineer find events in a large data set.

Data input control lets user fluidly input in hex or binary. Other products make the user choose a mode, often on another screen.
