To enable any SV ID, set "Satellites > SV Selection Criteria > Selection Mode > Man-
ual".
Remote command:
[:SOURce<hw>]:BB:GNSS:SVID<ch>:GPS:STATe
(etc. for the other GNSS systems)
Present in Constellation
If disabled, the SV ID is excluded from the currents constellation. The SV ID is auto-
matically deactivated ("SV ID > State = Off").
In the "Satellites" dialog, SV IDs that are excluded from the constellation are displayed
in gray color and are crossed out.
To reactivate such satellite, set "Present in Constellation > On" and activate it ("State >
On")
Remote command:
[:SOURce<hw>]:BB:GNSS:SVID<ch>:GPS:PRESent
(etc. for the other GNSS systems)
Power Offset
Reduces the signal of the selected SV ID by the defined value.
This is a global power offset parameter for a satellite. It affects the power level of all
signal components of a given satellite, see
"About satellite's (SV) power calculation"
Power changes are applied on-the-fly.
Remote command:
[:SOURce<hw>]:BB:GNSS:SVID<ch>:GPS:POWer:OFFSet
(etc. for the other GNSS systems)
Add Power Path-Loss
In "Test Mode = Navigation", enable this parameter to account for the free space
attenuation and simulate real-world conditions.
The power of the SV ID signals is reduced automatically. The power path-loss is calcu-
lated depending on the current satellite's orbit and the distance (range) between the
satellite and the receiver's position on the Earth, see
To observe the effect, select the "Monitor > Display > Power View", see
Remote command:
[:SOURce<hw>]:BB:GNSS:SVID<ch>:GPS:POWer:PLOSs
(etc. for the other GNSS systems)
Frequency Number
For GLONASS satellites, indicates the frequency number of the subcarrier used to
modulate the GLONASS satellite.
If "Nav Msg Type = NAV", the frequency number is retrieved from the imported config-
uration file.
