Rules of the Capture or Display Filter
•
There must be at least one IF and one ELSE statement per state. ELSE IF
statements are optional.
•
The Post Trigger Buffer Position must be greater than zero and less than 100.
•
There is always one and only one ROOT statement; you can’t delete the ROOT
statement.
•
In the capture filter, setting trigger will always set capture.
•
For devices other than THGm, Custom Counter 1 is the only counter that can be
used as a counter condition in a filter template. For THGm, all 7 custom
counters can be used as a counter condition.
•
The maximum number of states allowed is four for THGm.
•
The number of filters allowed depends on the analyzer-card hardware. A maxi-
mum of 16 total hardware filters are allowed for THGm modules, which can be
distributed across its four allowed states. Depending on the number of states, the
micro filters, and the logic combinations used, it is possible to exceed the maxi-
mum number of hardware filters. Contact Finisar customer support if you are
experiencing problems with writing complex filters that exceed the maximum
number of hardware filters.
