== Running a Uniform Frequency Sweep Simulation of the Urban Scene ==
In the first part of this tutorial lesson, you will perform a frequency sweep simulation of your propagation scene. Open [[EM.Terrano]]'s Simulation Run dialog and select '''Frequency Sweep''' as the simulation mode. Click on the Settings button next to this drop-down list to open the Frequency Sweep Settings dialog. In the frequency sweep settings dialog, select '''Uniform Sweep''' as the sweep type and set the values of the start and stop frequency to 0.5GHz and 1.5GHz, respectively, and set the number of frequency samples to 11. This will result in a frequency step of 100MHz. In the simulation run dialog, also check the box labeled '''Create Mean and Standard Deviation Coverage Mapsreceived power coverage maps''' in the "statistical Analysis" section of the dialog.

Now start the frequency sweep simulation of the Ann Arbor scene. At the end of the sweep simulation, a total pf 13 coverage maps are generated in the Observables sections of the navigation tree under the receiver Point Receivers set node. Of these, the first 11 maps correspond to the received power at each of the 11 frequency samples from 500MHz to 1.5GHz. The last two plots are the mean and standard deviation coverage maps over the specified frequency range.

The sweep variables list is initially empty. On the left side of this dialog, you see a list of all the available independent variables. Select the transmitter height variable "tx_h" from the left table and used the {{key|-->}} button to move it to the right table. Another dialog titled "Sweep Variable" opens up. You have to set the start, stop and step values of your sweep variable. By default, the sweep variable is of uniform type. Enter 2, 27, and 5 for start, stop and step values, respectively. This will create a value list of {2, 7, 12, 17, 22, 27}. Close the sweep variable dialog and then close the sweep settings dialog to return to the simulation run dialog. Uncheck the box labeled '''Create Mean and Standard Deviation Coverage Mapsreceived power coverage maps''' in the run dialog.
