• 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 Parity Error, Tx Parity Error — Finds a parity error based on the parity you
have set in the Bus Configuration Menu.
• Rx or Tx Any Error — Finds any error.
