* Right-click on the '''Transmitters''' item of the navigation tree and select '''Insert New Transmitter Set...''' from the contextual menu. This opens of the Transmitter Set dialog.
* Choose a name and color for your transmitter set.
* From the dropdown list labeled '''Associated Base Point Set''', select the desired set.
* In the "Custom Pattern [[Parameters]]", click the {{key|Import Pattern}} button to set the path for the radiation data file. This opens up the standard [[Windows]] Open dialog, with the default file type or extension set to '''.RAD'''. Browse your folders to find the right data file.
* You can also rotate the imported pattern about the three principal axes. Enter the rotation angles other than the zero default values, if necessary.
* Click the {{key|OK}} button of the dialog to close it.
A new transmitter set entry is added in the '''Transmitters''' section of the navigation tree. After defining a transmitter set, the base points associated with it change their color to the transmitter color, which is red by default. In the Transmitter Set dialog, you can also set the '''Baseband Power''' of your transmitter in Watts and its '''Phase''' in degrees. There is a check box labeled '''Custom Power''', which is checked by default. In that case, the power and phase boxes are enabled and you can change the default 1W power and 0° phase values as you wish. [[EM.Cube]]'s ".RAD" radiation pattern files usually contain the value of "Total Radiated Power" in their file header. This quantity is calculated based on the particular excitation mechanism that was used to generate the pattern file in the original [[EM.Cube]] module. When the "Custom Power" check box is unchecked, EM.Terrano will use the total radiated power value of the radiation file for SBR calculations.
EM.Terrano allows you to define a basic '''Heterodyne Transmitter Chain'''. Click the {{key|Transmitter Chain}} button of the Transmitter Set dialog to open the Transmitter Chain dialog. As shown in the figure below, you can specify the characteristics of the baseband/IF amplifier, mixer and power amplifier (PA) including stage gains and impedance mismatch factors (IMF) as well as the characteristics of the transmission line segment that connects the PA to the antenna. Note that the transmitting antenna characteristics are automatically filled from using contents of the radiation file. The transmitter Chain dialog also calculates and reports the "Total Transmitter Chain Gain" based on your input. When you close this dialog and return to the Transmitter Set dialog, you will see the calculated value of the Effective Isotropic Radiated Power (EIRP) of your transmitter in dBm.
Receivers act as observables in a propagation scene. The objective of a SBR simulation is to calculate the far-zone electric fields and the total received power at the location of a receiver. In that sense, receivers indeed act as field observation points. You need to define at least one receiver in the scene before you can run a SBR simulation. You define the receivers of your scene by associating them with the base sets you have already defined in the project workspace. Unlike transmitters that usually one or few, a typical propagation scene may involve a large number of receivers. To generate a wireless coverage map, you need to define an array of points as your base set.
To define a new Receiver Setreceiver observable in EM.Terrano, go to follow the Observables section of the Navigation Tree, right procedure below:Â * Right-click on the '''Receivers''' item of the navigation tree and select '''Insert New ReceiverSet...''' A dialog from the contextual menu. This opens up that contains a default name for of the new preliminary Receiver Set as well as dialog.* Choose a name and for your receiver set. * From the dropdown list labeled '''Select Radiator Associated Base point Set'''. In this list you will see all the available base sets that you have already define in the project workspace. Select and designate , select the desired base set as .* Click the {{key|OK}} button of the dialog to close it. Â A new receiver set. Note that if entry is added in the base set contains more than one point, all '''Receivers''' section of them are designated as receiversthe navigation tree. After defining a receiver set, the base points associated with it change their color to the receiver color, which is yellow by default. The first element of the set is represented by a larger ball of the same color indicating that it is the selected receiver in the scene. Â The Receiver Set Dialog is also used to access individual receivers of the set for data visualization at the end of a simulation. At the end of an SBR simulation, the button labeled "Show Ray Data" becomes enabled. Clicking this button opens the Ray Data Dialog, where you can see a list of all the received rays at the selected receiver and their computed characteristics.
