* 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.
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.
{{Note| If you do not modify the default [[parameters]] of the transmitter chain, a 50-Ω conjugate match condition is assumed and the power delivered to the antenna will be -3dB lower than your specified baseband power.}}
