# 3.2.2 System to be a victim

In order to set up a workspace, the first step is to set the system that will be used as victim: set the characteristics of the receiver (that will be the **victim link receiver** (VLR)) and the transmitter (that will be the **victim link transmitter** (VLT)).

System characteristics can be directly edited in the system tab. This is illustrated in the figure below.

For example, a generic system can be selected from the “import system from library button” as shown Figure 67.

First, let set the frequency of the victim. The frequency can be changed from 900 MHz (default value) to 1000 MHz as described in Figure 68. In this example a constant value is considered, but in principle any type of distribution can be selected.
