Example:
BB:GPS:SMOD LOC
satellite signals are generated corresponding to a 'real' location.
BB:GPS:PDOP?
queries the PDOP of the selected satellite constellation.
Response: '2.80'
Usage: Query only
[:SOURce<hw>]:BB:GPS:POWer:ADJust
(R&S SMx/AMU instruments only)
Calculates the power level of each satellite so that the sum of all levels results in 0 dB.
Example:
BB:GPS:POW:ADJ
the total power of all satellites is set to 0 dB, the power ratio among
the satellites is unchanged.
Usage: Event
[:SOURce<hw>]:BB:GPS:POWer[:TOTal]?
(R&S SMx/AMU instruments only)
Queries the total power of all satellites. After "Power Adjust", this power corresponds to
0 dB.
Return values:
<Total> float
Example:
BB:GPS:POW?
queries the total power of all satellites.
Response: -22.5
the total power is -25 dB.
Usage: Query only
[:SOURce<hw>]:BB:GPS:SATellite<st>:ADSHift <Adshift>
(R&S SMx/AMU instruments only)
Sets the additional Doppler shift of the simulated signal of the satellite.
Additionally, the parameter can be used to simulate multipath conditions.
To simulate multipath, assign the same space vehicle (SV ID) to more than one simulated
satellites and set different "Additional Doppler Shift".
