Chapter 5: Scenario Definition
This chapter guides you through specifying and using the GSS7725 within SimGEN.
5.1 Signal types
SimGEN
specifies individual signal types for each antenna.
In the Scenario contents window of SimGEN, expand the vehicle and then expand the antenna.
Next, select Signal Types: and either: right-click and select Edit, or double-click Signal Types: to
show the Antenna Signal Types dialog, see Figure 5.
Figure 5 Antenna Signal Types dialog
Select the signal type you want to use.
After you have clicked OK, you may see the message "Incompatible h/w" appearing in the bottom
right hand corner of the SimGEN
window. The most likely cause for this error message is that the
requested hardware is unavailable for that antenna. For example, you may be trying to select
interference on antenna 2 when interference, as defined by the currently selected hardware
configuration, is only available on antenna 1.
After you have selected Antenna Signal Types - Interference, you must specify the GSS7725
operating mode from:
a) Use File (see Section 5.2).
In Use File, the interference source uses an interference file whose parameters you define
using the Interference Simulation File editor.
b) Interactive (see Section 5.3).
In interactive mode you use SimGEN
to modify the interference power in real-time.
