MOSI data, MISO data, and framing signal, then setting the threshold voltage level for each input
channel, and finally specifying any other signal parameters.
To set up the oscilloscope to capture SPI signals:
1. Press the Decode button to enter the DECODE menu.
2. Press the Decode softkey to select the desired slot (Decode 1 or Decode 2).
3. Press the Protocol softkey and select SPI with the Universal Knob and press the knob to
confirm.
4. Press the Signal softkey to enter the SPI SIGNAL menu.
