Switching delay
Specifies how much time is required for the antenna switching to settle in order to prevent hot switching.
•
Break before make delay
Allows adjusting this delay parameter if RF box requires break before make delay.
•
Switching table
Defines relationship between InVectors and Outputs. For each InVector the Output states can be
specified separately. InVectors can be edited but they must match the InVectors defined on the
Directions tab.
Rules
Rules tab specifies frequency range of the
antenna's R port along with two another settings.
Frequency ranges and Include to selection boxes
were explained previously.
Fit mask
serves a special purpose; it tells Router
how to handle InVector. In the case of Vertical
Array Antenna, if Fit mask is set to its default
value (all zeros), it means that the array will be
added as one, main selection on SMD with
direction control on the sub selection buttons [1]...
[4]. If Fit mask is changed, for example to 10000,
selection list will contain a main array selection
as before and a separate selection which has the
same InVector as Fit mask. In our four square
antenna example this would mean the main
selection and an extra position for North.
Fit mask also allows the special character X in
addition to 1 or 0 where X stands for a mask. In
our case, if Fit mask is xx000 there will be three options available for SMD front panel; a global one for the array
and additional for selections with InVector equal 10000 and 01000 (Fit mask 11000 would be invalid in this case
invalid because that InVector does not exist). In our four square antenna, this means the available selections will
be main, North and East.
Buttons
All RF boxes which have more than one InVector defined can also have associations between InVectors and the
Subselection
buttons. These associations are defined on the Buttons tab and shows which InVector will be
requested by SMD for every combination of the subselection buttons. There are fifteen (15) valid combinations
(all buttons Off is not valid).
InVector can be explicit like 10000 or contain special characters. X means
“don't change last state”
for this bit
and T means
“invert (or toggle) the last state”
of this bit.
Properties
field will be described in RF box – Switch – Stack Switch chapter.
OTHER ANTENNA
Other Antenna is a choice for all other antennas which do not fit either Single Antenna or Vertical Array antenna
template. Settings are the same as the other antenna types and can be edited without limits.
