Position ← MOSI and MISO data conditions
Operator for the data position. You can defined an exact position, a position range, or let
the position undefined ("Any").
SCPI command:
TRIGger<m>:SPI:DPOPerator on page 669
Index min, Index max ← MOSI and MISO data conditions
The effect of data positioning depends on the Search mode. It sets the number of bits or
words before the first word of interest. These offset bits/words are skipped. If the position
operator defines a range, the first and the last bit/word of interest are defined. The index
0 is associated with the first data bit or word.
SCPI command:
TRIGger<m>:SPI:DPOSition on page 669
TRIGger<m>:SPI:DPTO on page 670
Search mode ← MOSI and MISO data conditions
Defines how the specified data pattern is searched:
"Word-aligned"
The pattern is matched only at word boundaries.
"Bit-aligned"
Bit-by-bit: the pattern can start at any position in the message.

10.3.3.3 SPI Decode Results (Option R&S RTO-K1)
If the option is installed, the "Decode" function in the "Configuration" tab is available.
Enable "Decode" to display the decoded signal below the waveforms.
Additionally, you can display the binary signal and the detailed decoding results, see 
chapter 10.1.2, "Display", on page 251.
