SPI Serial Decode
To set up the oscilloscope to capture SPI signals, see “Setup for SPI Signals" on
page 445.
To set up SPI serial decode:
1 Press [Serial] to display the Serial Decode Menu.
2 Press the Word Size softkey; then, turn the Entry knob to select the number of
bits in a word.
3 Press the Bit Order softkey; then turn the Entry knob to select the bit order, most
significant bit first (MSB) or least significant bit first (LSB), used when
displaying data in the serial decode waveform and in the Lister.
4 If the decode line does not appear on the display, press the [Serial] key to turn it
on.
5 If the oscilloscope is stopped, press the [Run/Stop] key to acquire and decode
data.
You can use the horizontal Zoom window for easier navigation of the acquired data.

NOTE
For SPI triggering setup see “SPI Triggering" on page 449.
NOTE
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.
