SPI triggering and serial decode is available on DSOX1200-Series oscilloscopes.
The 2-channel DSOX1200-Series oscilloscopes support 3-wire SPI (Clock, Data,
and CS). The 4-channel DSOX1200-Series oscilloscopes support 4-wire SPI
(Clock, MOSI, MISO, and CS).
Setup for SPI Signals
Serial Peripheral Interface (SPI) signals setup consists of connecting the
oscilloscope to a clock, 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, use the
Signals
softkey which
appears in the Analyze menu:
1
Press
[Display] > Labels > Display
to turn on labels.
2
Press the
[Analyze]
key.
NOTE
Only one SPI serial bus can be decoded at a time.
