8.6 Advanced Filtering Mode
622Vu Advisor’s advanced filtering features let you define a filterset-level mask
that's combined with all other selection criteria when choosing the cells to
include. This lets you specify a particular characteristic that you want across all
captured cells, for example, or header fields you want to ignore completely
If you mark the Advanced Filtering Mode option for a filterset, the filterset
definition and filter-entry definition windows offer enhanced masking capa-
bilities. The filterset definition window lets you specify a filterset mask, and the
filter-entry window uses that mask to offer extended filtering options.
Specifying a FilterSet Mask
With Advanced Filtering Mode on, the filterset definition window changes to
include a filterset mask:
Use the FilterSet Mask
area to identify those
bit positions you want
to examine, within
each incoming cell.
This lets you define a mask that’s similar to the idle-cell mask described earlier,
but in this case the mask identifies those bit positions you want to examine in
each cell coming into the analysis device, for purposes of determining whether to
capture the cell. Presumably at least one filter-entry definition references each
bit position you ask 622Vu Advisor to examine.
You can examine any of the header bits, as well as the first byte of the payload.
(This first payload byte lets you select AAL1 cells based on their SAR, for
example.)
