b.
Turn the Universal Knob to select the channel connected to the SPI serial clock line.
c.
Press the Threshold softkey and turn the Universal 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.
d.
Press the Edge Select softkey to select rising edge or falling edge for the selected clock
source. This determines which clock edge the oscilloscope will use to latch the serial data.
6. Press the
softkey to return to the SIGNAL menu.
7. Press the MISO softkey to enter the SPI MISO menu.
In the MISO menu:
a.
Press the MISO softkey and turn the Universal Knob to select the channel that is
connected to a second SPI serial data line. If the channel selected is off, it should be
switched on. You can also select Disable.
b.
Press the Threshold softkey and turn the Universal Knob to select the MISO 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.
8. Press the
softkey to return to the SIGNAL menu.
9. Press the MOSI softkey to enter the SPI MOSI menu.
Figure 112 - MOSI menu
In the MOSI menu:
a. Press the MOSI softkey and turn the Universal Knob to select the channel that is
connected to a SPI serial data line. If the channel selected is off, it should be switched on.
You can also select Disable.
b. Press the Threshold softkey and turn the Universal 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 the selected serial decode slot.
10. Press the
softkey to return to the SIGNAL menu.
11. Press the CS softkey to open the SPI CS menu.
Figure 113 - SPI CS Menu
In the CS menu:
a. Press the Cs Type softkey to select a framing signal that the oscilloscope will use to
determine which clock edge is the first clock edge in the serial stream. You can set the
oscilloscope to trigger during a high chip select (CS), a low chip select (~CS), or after a
Timeout period during which the clock signal has been idle.
