[2]
Cable skew is measured at each SCSI device connection within the same bus segment with the transmit-
ted skew subtracted from the received skew.
[3]
Calculated assuming timing budget shown in Table 9.
[4]
Measured at the receiver terminal using clean input signals with 500 mV peak amplitude and 1 ns rise and
fall time between 20% and 80% of the signal.
[5]
Relative to the REQ(ACK) clocking signal.
Note. Fast-160 SCSI devices shall not change timing parameters between training (see Section 3.5.3.1) or
reset events (see Section 5.4).
