The Filter Tab is not available on
· Stealth Series in Symbol Recorder mode
Actual available options for filtering depend on the analyzer model used.
An example of the Filter page is shown below.
You can select on this page which packets and events should be skipped.
In the Skip by packet type box you can select packet types to be skipped. You can also select some
error types to skip packets with the selected error types. In the example below, all Cycle Start packets will
be skipped. Note that you can even skip the Phy-SelfID packets. When you do this, the software will not
be able to show a Topology for the corresponding (skipped) Phy-SelfID packets.
In the Skip by packet Set(s) box you can specify a packet Set or any boolean combination of the four
packet Sets. All packet that fits the described Sets will be skipped. In the example below, all packets that
fits both packet SetA and SetB will be skipped. Note that a red cross will be displayed before the boolean
expression when there is an error in the expression
Using the Skip by speed box you can skip all packets of particular speed. When checking the Skip all
S800 for instance, no S800 packets will be recorded.
In the Skip prefix-only packets box you can specify to skip prefix-only packets. When you check the
Skip all prefix-only packets checkbox, no prefix-only packets will be recorded. When this checkbox is not
checked and the Skip short prefix_only packets checkbox is checked, only the short prefix_only packets
will be skipped. This option is by default on. It is used to skip the short prefix-only packets that are
sometimes generated by the 1394b phy interface when sending a bus status event.
