Channel Settings
The Channel Settings page lets you to set speed, descrambling and packing options for
each channel. It also lets you inhibit channel recording.
Speed
Settings
The SASTracer systems support Autodetect Link Rate which is designed to pass through
the speed negotiation signaling allowing the initiator and device to determine the link
speed using the method defined in the SAS specification. In general, this is the most
convenient setting to use because it ensures the traffic will get recorded at the negotiated
rate. Alternatively, users may force the analyzer to record at the 1.5G or 3G rate.
However, if the negotiated link speed is higher or lower than the speed selected in this
tab, analyzer will not decode the traffic properly (there will be errors in the trace). The user
will know if devices are negotiating successfully by getting clean recordings.
Channel
Settings
These options allow you to inhibit recording and turn off scrambling and packing on a
channel by channel basis.
Inhibit - Inhibits recording of traffic from selected channels. For example, if you check
the option for T1, it means "record all channels except for Target channel 1 (T1)."
No Descrambling - Turns off the analyzer’s descrambling from the selected channels.
Select this option if your DUTs are not scrambling their traffic.
No Packing - Turns off primitive and idle packing from the selected channels.
