Exchange View

In Exchange View the elements of a event are grouped together hierarchically rather than sequentially.

Traffic Summary View

The Traffic Summary View for each captured signal can be viewed. This Summary View displays the statistics of commands, the type of command and the total count. For each command it displays the percent of the total count. See Traffic Summary View for more information.

The software collects up to 10,000 unique pairs for the reports. Anything beyond that is grouped into the Others category.

Multi-Column Sorting

Press the Shift key while clicking on the header section to sort the columns one-by-one in the priority order. In the case of multi-column sorting, the sort priority order will be shown in the form of indexes as part of the header title.

Data View

Click on Analysis and select Data View or click the att_45_for_519962646.png icon to display Data View.

Data View displays information in Hexadecimal and ASCII format. See Data View for more information.

Bus Utilization View

Bus Utilization View displays both an Error Count and Link Utilization over a specific time frame.

Typical Bus Utilization View (Ports P1 and P6 Showing)

For a more detailed explanation, see Bus Utilization View.

Link State View is used for debugging Auto Negotiation and Link Training in Ethernet, and Speed Negotiation and TX Training in Fibre Channel. The Link Viewer is intended to show events chronologically. Transitions will not be shown on this view. All the errors that occur in the Trace will be shown in the Event Viewer.

Link State View can be enabled by selecting the Link State View att_48_for_519962646.png icon in the main toolbar (between Bus Utilization and Export to Wireshark). It has four main views:

  • Timeline View

  • Listing/State Diagram View

  • Navigation View

The Link State View also has its own toolbar.

Verification Script

The Verification Script Engine allows you to select from available traces and execute verification scripts on them. For more details, see Verification Script Engine (VSE).

RTT Pairs

Round-trip time (RTT), also called round-trip delay, is the time required for a signal pulse or packet to travel from a specific source to a specific destination and back again. In this context, the source is the computer initiating the signal and the destination is a remote computer or system that receives the signal and retransmits it. For more details, see Round Trip Time (RTT) Pairs.
