Number of Echos
Sets the echoes number. The value determines the number of rows available for con-
figuration.

(etc. for the other GNSS systems)
Line of Sight (LOS)
Defines if a LOS component is present or not.

LOS and Echoes Table
Configuration of the LOS signal and the echoes, one row per multipath tap, where:
●
LOS is present if "Line of Sight (LOS) > On"
●
Number of echoes is defined by the parameter "Number of Echos"
Unit ← LOS and Echoes Table
You can change the units of the parameters. The affected values are automatically
recalculated.
Note: The selected units are used only in the manual control (display).
In remote control, SCPI commands always use the default units.
Init. Code Phase ← LOS and Echoes Table
Sets an initial code phase (or delay) for the selected echo. To simulated echo delay
variation with the time, set the parameters
Code Phase Drift and Doppler Shift /Hz .
The severity of the multipath effect depends on the delay of the echoes and their
power.
