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 Avalanche systems are designed to 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,
3G or 6G 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 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.
