4 Triggering the Oscilloscope
To use SPI triggering
Serial Peripheral Interface (SPI) trigger setup consists of
connecting the oscilloscope to a clock, data, and framing signal.
You can then trigger on a data pattern that occurs at the start of
a frame. The serial data string can be specified to be from 4 to
32 bits long.
When you press the Settings softkey, a graphic will be displayed
showing the current state of the frame signal, clock slope,
number of data bits, and data bit values. Press the Signals
softkey in the Settings menu to see the current source channels
for the clock, data, and frame signals.
Press the More key in the Trigger section of the front panel,
rotate the Entry knob until SPI is displayed in the Trigger
softkey, then press the Settings softkey to display the SPI
trigger menu.
NOTE For SPI decode information see page276.
