• Rx Data — Finds a data byte that you specify. For use when the DUT
data words are from 5 to 8 bits in length (no 9th (alert) bit).
•
Rx 1:Data
— For use when the DUT data words are 9 bits in length
including the alert bit (the 9th bit). Finds only when the 9th (alert)
bit is 1. The specified data byte applies to the least significant 8 bits
(excludes the 9th (alert) bit)
•
Rx 0:Data
— For use when the DUT data words are 9 bits in length
including the alert bit (the 9th bit). Finds only when the 9th (alert)
bit is 0. The specified data byte applies to the least significant 8 bits
(excludes the 9th (alert) bit).
•
Rx X:Data
— For use when the DUT data words are 9 bits in length
including the alert bit (the 9th bit). Finds a data byte that you
specify regardless of the value of the 9th (alert) bit. The specified
data byte applies to the least significant 8 bits (excludes the 9th
(alert) bit).
• Similar choices are available for Tx.
• Rx or Tx Parity Error — Finds a parity error based on the parity you have
set in the Bus Configuration Menu.
•
Rx or Tx Any Error
