Frequency offset
The frequency offset refers to nominal frequency of the selected signal/frequency slot.
Power, Position
It is possible to simulate a location-based jamming signal by specifying a position for it. Loca
tion-based jamming simulation utilizes the jamming signal
power, and position to calculate the
distance from the simulated position, applying the path loss formula given earlier in this doc
ument (see "Signal Power Level Considerations" on page 23) to calculate the power of the
received jamming signal. As the scenario position moves closer to the location of the jamming
transmitter, the jamming power increases, and vice versa.
When configuring a location-based jamming source, the distance to the scenario start position
and the jamming coverage are shown, in order to assist you in designing a reasonable jam
ming test configuration.

Configuring the position of a jamming source
Note that the jamming power can be set to +60 dBm, whereas the maximum GSG power level
is -65 dBm.
Example
The figure below shows a configuration of a sweeper interference signal for the L1, L2 and L5
bands (OPT-JAM installed).

This feature allows you to configure a Base station , as it is typically used for high-precision pos
itioning, e.g. in surveying applications: A receiver in a fixed and known position tracks the
