6.4.5.4. Data Type

The Data type control specifies the type of data pattern contained in the transactions. Select the following available data types for analysis:

  • PRBS7 —pseudo-random 7-bit sequences (default)
  • PRBS15—pseudo-random 15-bit sequences
  • PRBS23—pseudo-random 23-bit sequences
  • PRBS31—pseudo-random 31-bit sequences
  • HF—highest frequency divide-by-2 data pattern "10101010"
  • LF —lowest frequency divide by 33 data pattern

Settings HF and LF are for transmit observation only and are not intended for use in the receiver data detection circuitry.
