
Touching anywhere else on the table shows a pop-up with Off, Zoom, Setup..., Export, and
Measure... choices.

Decoding of an entire acquisition with very long acquisitions including thousands of messages
takes longer than shorter acquisitions.
3. Source Selection - Touch these selections to open a pop-up dialog where you can select sources for Data,
and (for some protocols) controls for Clock and other lines - for example Chip Select for SPI .
PLEASE NOTE THE FOLLOWING:

Source selection is dynamically linked to the Protocol selection, so the appearance and number of
sources to choose changes based on your selected Protocol.

Source can be a Channel (C1 – C4), a Memory Trace (M1 – M4), a Math Function (F1 – F4), or
digital lines (D1 - D36 on MS-250 or MS-500).

Use a Channel for a new, real-time acquisition.

Use a Memory for recalling saved data from a previous acquisition for further analysis. Refer to
your oscilloscope’s Save and Recall Waveforms topic for more details.

Use a Math Function to view decoded data on Sequence mode acquisitions. Sequence Mode is a
unique capability where you can utilize oscilloscope memory to capture events widely spaced in
time and then view them sequentially. Reference the chapter on Isolating and Analyzing Serial Bus
Activity for more information on setting the oscilloscope up in this mode.
4. Protocol Selection - Touch this selection to open a pop-up dialog box and choose a protocol decoder.
Depending on the decoder selected, the correct inputs (Clock, Data, and a third line, if required) are
shown to the left.
