Using Midian's InterMod Calculator
To get to the color configuration, go to the main menu entry labeled "Options" and click on the menu entry labeled "Color Configuration." This will bring up the window labeled "Options" as shown below.
Click on one of the available buttons to bring up the color palette (shown above on right) to change the color of the associated frequency or name you desire.
This enables you to colorize your reports for visually separating the transmitter frequencies from the receiver frequencies and distinguishing the hit frequencies from the near hit frequencies.
The screen-shot below is the first window and the Main Window of the InterMod Calculator that you will see when creating a New Site.
To create a new site, click on the "Create New Site" button. The Main Screen will "blank out" and the default values for a "New Site" will be placed in the parameter fields. Now tab down past the "Site Selection Quick Pick" field to the "Selected Site Current Parameters" section to the field labeled "Site Name" and enter in the desired name for this site.
Tab down to the "Low Order" field and enter a "3" to start with a 3rd order study. Tab over to the "High Order" field and enter a "5" to end with a 5th order study. If no results are achieved here, then increase your "High Order" to a "7", "9" or "11" order.
Tab down to the "Near Hit Window" and enter how many KHz. you will accept as a near-hit. 25 to 30 KHz. is probably good enough for a 3rd and 5th order study. 35 to 50 KHz. is good for a 7th to 9th order study.
Tab over to the "Odd Orders Only" checkbox and check it if you are interested in odd order only studies. If you leave it unchecked then both odd and even order studies will be calculated. For example, if you put a Low Order of "3" and a High Order of "5", you will wind up with a 3rd odd order study, a 4th even order study and a 5th odd order study.
Tab down to the "In Band Only" checkbox and check it if you are NOT interested in calculations that produce out-of-band products.
Tab down to the "Save Changes to Selected Site" button and click on it to save all the changes you have just made to the site.
Tab over to the right side of the Main Screen to the "Location(s) at Site:" and click the button labeled "Create New Location at Site" which will bring up a similar screen of the screen shot shown below.
Below is a screen-shot example of a location that has been filled in:
The title bar of the above window now shows the site name that was entered in the previous step. You can now enter in building or floor names as locations at this site. You may now tab down to the description window and enter in descriptive information regarding the location that you are creating. Some examples of this types of information are Latitude and Longitude coordinates, Street Address, Point of contact, description of the area.
Now tab down to the button labeled "Create New User/Frequency for this Location" for the named site and press the "ENTER" key.
Below is a screen-shot of a filled in User/Frequency example.
The example above shows the screen-shot labeled "Add New User/Frequency to Location: Federal Building" where "Federal Building" is the name of the Location at the "Tumamoc Hill Site." You can then install customers into this location starting with the labeled field "User/Frequency Name."
The "User/Frequency Name" field is used to give a name (customer or descriptive) to a frequency pair or you may decide to split the frequency pair apart and make two separate entries (1 entry for transmit and 1 entry for receive).
Tab down to the TX and RX fields and enter the assigned radio frequencies. Once you assign a Receive Frequency the Receiver (IF) field will become enabled and you can then enter in the Receiver (IF) if applicable. Otherwise leave the Receiver (IF) field set to the 0.000 value.
Please NOTE: The Receiver (IF) field is rarely used. Refer to the manufacturer service manual for the particular model of radio to determine the high IF frequency.
Tab down to the button labeled "Add this User/Frequency" and press "ENTER". This will bring you back to the previous window (Location Details For the Selected Site) and you will see the new customer you have just added to the location show up in the grid labeled "View the User/Freq. At this Location." To add more customers just repeat the same steps.
The Location List (customers) can be edited or removed with the buttons located in the group box labeled "Location List Changes."
The last step is to return to the Main Screen and click on the button labeled "Perform Intermodulation Calculation on the Selected Site." Depending on the number of locations, number of frequencies and especially the value of the higher order window will determine the length of time needed to perform the calculations. The screen shot below has an indicator box that depicts the remaining calculations that are needed to finish the study.
