❸ In the frequency criteria box, there are the parameters about rules for calculation of the
solutions:
- Other Carrier: indicate the minimum distance from a solution carrier to another.
-
Avoid Carrier: indicate the minimum distance of a solution carrier from an avoid
carrier.
-
Intermod 2(TX): indicate the minimum distance between the solutions carriers and
the intermodulations products that are generate when there are 2 TX near.
-
Intermod 3(TX): indicate the minimum distance between the solutions carriers and
the intermodulations products that are generate when there are 3 TX near.
-
Forbidden Areas: indicate the minimum distance of the solutions carriers from a
forbidden area.
Another parameter in this box is the “Intergap BW” that indicate the intergap bandwidth
between two TV channel.
Under “Intergap BW” there is the Protection Level list box where it’s possible to set one of
the four preloaded protection configurations (High, Medium, Low or Low (2TX Only)) or
the Custom configuration (only with “Custom” it’s possible to change the values).
We advise to use an high protection to avoid any intermodulation but in some cases, with
an high protection, the program can find few solutions. In these cases, if are necessary
other solution, it's possible to reduce the protection to try to find more solutions.
❹ Here it’s possible to set the number of solutions that the calculator must found and START
the calculation. The solutions found appear in the right column on the “FREQUENCY
CALCULATOR” panel and the number of frequencies found is written in “Found Solutions”
❺ In the Save box the solutions found can be saved as a wdf. file:
-
Select SAVE as WDF
-
Select as
Group#
the first free group on the rx/tx
-
Give a name and descriptionn to the plan
-
Select lock Channels: in this way the user can not modified the group only using
Wisycom Manager (MRK960) o IR Programmer (MTPxx, MTHxxx)
