Parameters:
<Adshift> float
Range: -100.0kHz to 100.0kHz
Increment: 0.1Hz
*RST: 0.0Hz
Example:
BB:GPS:SAT1:VID 4
sets space vehicle 4 for the first satellite.
BB:GPS:SAT2:VID 4
sets space vehicle 4 for the second satellite.
BB:GPS:SAT1:ADSH 10.5kHz
sets the additional Doppler shift of satellite 1 to 10.5 KHz
BB:GPS:SAT2:ADSH 1kHz
sets the additional Doppler shift of satellite 2 to 1 KHz
[:SOURce<hw>]:BB:GPS:SATellite<st>:APOWer <Apower>
(R&S SMx/AMU instruments only)
Sets the additional power of the satellite in dB.
Additionally, the parameter can be used to simulate multipath conditions.
To simulate multipath, assign the same space vehicle (SV ID) to more than one config-
uration columns (simulated satellites) and set different "Additional Power".
