Triggering the Oscilloscope 4
6000 Series Oscilloscope User’s Guide 179
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.
