Note: Noise interference is not available if wide band noise is set to
ON under the Options > Transmit power menu.
Satellite ID/Frequency slot
For GPS, SBAS, Galileo, GLONASS, BeiDou, IRNSS and QZSS signals, the Satellite ID
must be specified.
For GLONASS carrier signals the Frequency slot must be specified.
In some instances, this field is not applicable, and will be grayed out (e.g., GPS carrier).
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 cal-
culate the distance from the simulated position, applying the path loss formula given earlier
in this document (see
"Signal Power Level Considerations" on page 24 ) 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 pos-
ition and the jamming coverage are shown, in order to assist you in designing a reasonable
jamming test configuration.
Figure 3-13:
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).
