5 Press the Clock softkey to open the SPI Clock Menu.
In the SPI Clock Menu:
a Press the Clock softkey; then, turn the Entry knob to select the channel
connected to the SPI serial clock line.
The CLK label for the source channel is automatically set.
b Press the Threshold softkey; then, turn the Entry knob to select the clock
signal threshold voltage level.
The threshold voltage level is used in decoding, and it will become the
trigger level when the trigger type is set to the selected serial decode slot.

selected Clock source.
This determines which clock edge the oscilloscope will use to latch the serial
