13.2.6.2 Triggering on SPI
Prerequisites: A bus is configured for the SPI signal to be analyzed. See Chap-
ter 13.2.6.1, "Configuring SPI signals", on page 305.
For details on configuration settings, see Chapter 13.2.2, "SPI configuration",
on page 294.
1. Open "Menu" > "Trigger".
2. Set "Trigger on" to "Single event".
3. Ensure that the "Source" is set to the configured serial bus, e.g. "Serial bus 1".
4. Select the "Type".
5. Define additional settings for more complex trigger types ("MOSI"/ "MISO"):
a) Tap on "Set details".
b) Set the "Search mode".
c) Set the "Data pattern" or a data range.
In the following example a decode for triggering on "MOSI" triggered on "Data pat-
tern" = 0x41.
Figure 13-4: Trigger on Type= MOSI, Data pattern = 41
13.2.6.3 Exporting decode results
Once a decode has been completed, you can export the decode results of the
SPI bus (option R&S
MXO5-K510)
