Primitive Response Timeout
The Primitive Response Timeout parameter specifies the number of DWORDs between
two pair primitives after which the analyzer detects a protocol error. Default value is
65000. When host or device sends a primitive, such as X_RDY, HOLD, or WTRM, it expects
device or host to reply with a primitive, such as R_RDY, HOLDA, or R_OK. This parameter
detects FIS Signaling Latency error, between HOLD and HOLDA, and FIS State Transition
error, between X_RDY and R_RDY, between SOF and EOF, or between WTRM and R_OK or
R_ERR.You can set a trigger on these protocol errors.
Disable Scrambling
If checked, causes the Analyzer to assume that no traffic is scrambled. By default, the
Analyzer assumes the scrambling state of the devices under test
