On 2-channel DSOX1200-Series oscilloscopes (that support 3-wire SPI), press
the
Data
softkey to open the SPI Data menu.
In the SPI Data menu:
a
Press the
Data
softkey; then, turn the Entry knob to select
the channel that is connected to a SPI serial data line. (If
the channel you selected is off, switch it on.)
The Data label for the source channel is automatically set.
b
Press the
Threshold
softkey; then, turn the Entry knob to
select the data 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.

On 4-channel DSOX1200-Series oscilloscopes (that support
4-wire SPI), press the
MOSI
softkey to open the SPI MOSI
menu.
In the SPI MOSI menu:
a
Press the
MOSI Data
softkey; then, turn the Entry knob to
select the channel that is connected to a SPI serial data
line. (If the channel you selected is off, switch it on.)
The MOSI label for the source channel is automatically set.
b
Press the
Threshold
softkey; then, turn the Entry knob to
select the MOSI 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
