Limits for Inner Offsets
Since inner offsets are defined from the sub-block edges to the gap, limits from two
sub-blocks overlap each other. Therefore, the limit used for inner offsets are the
cumulative sum of limits from both sub-blocks. Offsets can have different RBWs,
which must be compensated when accumulated.
For example, when offset A and D overlap, the limit of offset A is calculated as
follows.
Th
e diagram below depicts what inner offset limits look like.
Offset (Bandwidth)
Enables you to set up the bandwidth measurement parameters for offset pairs. For
example, you can assign the start and stop frequencies, and select the resolution
bandwidth.
