Serial Decode/Lister 10
InfiniiVision Oscilloscopes User’s Guide 327
You can use the Zoom horizontal sweep mode for easier navigation of the acquired data.
Interpreting SPI Decode
• Angled waveforms show an active bus (inside a packet/frame).
• Mid-level blue lines show an idle bus.
• The number of clocks in a frame appears in light-blue above the frame, to the right.
• Decoded hexadecimal data values appear in white.
• Decoded text is truncated at the end of the associated frame when there is insufficient
space within frame boundaries.
If the setup does not produce a stable trigger, the SPI signal may be slow enough that the
oscilloscope is AutoTriggering. Press the [Mode/Coupling] key, then press the Mode
softkey to set the trigger mode from Auto to Normal.
