RF Band
Selects the GPS carrier frequency used for Doppler calculation.
"L1"
Selects GPS carrier frequency L1 = 1.57542 GHz.
"L2"
Selects GPS carrier frequency L2 = 1.2276 GHz.

Oversampling
(R&S WinIQSIM2 only)
Determines the upsampling factor.
A higher upsampling factor improves the filtering but increases the waveform size pro-
portionally. This leads to limitation for the maximum "Duration of Satellite Simulation".

AGPS Test Scenario
(enabled with option Assisted GPS (R&S-K65) only)
Selects a predefined A-GPS test scenario according to A-GPS 2G/3G Protocol and Con-
formance Test Cases.
"User Defined"
No predefined test scenario is selected. The parameters can be set by
the user.
