Data setup
Specifies the data conditions:
Position
← Data setup
Operator for the data position within a frame. You can define an exact position, or a
position range. Select "Any", if the position of the required pattern is not relevant.
SCPI command:
TRIGger<m>:I2C:DPOPerator on page 652
Index min, Index max ← Data setup
Sets the number of data bytes to be skipped after the address. The index 0 is associated
with the first data byte. If the Position defines a range, the first and the last byte of interest
are defined.
SCPI command:
TRIGger<m>:I2C:DPOSition on page 653
TRIGger<m>:I2C:DPTO on page 653
Condition ← Data setup
Selects the operator for the "Data" pattern: "Equal", "Not equal", or a range definition.
SCPI command:
TRIGger<m>:I2C:DCONdition on page 653
Value min / Value max ← Data setup
Specifies the data bit pattern. Enter the bytes in msb first bit order. The maximum pattern
length is 64 bit. Waveform data is compared with the pattern byte-by-byte.
The instrument ensures that the max value is always ≥ the min value, and X bits (don't
care) are at the same position in both values.
The bit pattern editor helps you to enter the pattern, see chapter 10.1.4, "Bit Pattern
Editor", on page 255.

10.2.3.3 I²C 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.
