2. Enable the instrument to work in "Localization Mode Auto SV Selection".

Note: Do not use the "Auto SV Selection and Update" mode for the generation of A-

GPS test signals.

3. Select "Full Configuration" mode.

4. Select the "Satellite Configuration" and reconfigure the satellites' parameters as

required.

5. Configure the "Navigation Message" and for instance adjust the ionospheric model

per satellite.

6. Set the GPS "State" to ON to enable the GPS signal generation.

7. Generate the required "Assistance Data".

The R&S Signal Generator generates an A-GPS signal according to the settings

made.

2.8.6 Generating A-GPS Test Signal

(for R&S SMx/AMU instruments equipped with option Assisted GPS (R&S-K65) only)

The generic workflow for generation of A-GPS test scenarios in conformance to A-GPS

2G/3G Protocol and Conformance Test Cases is as follow:

1. Execute "Set To Default" to adjust the instrument's settings to a standard set of oper-

ating conditions.

2. Select a predefined GSM or 3GPP FDD "AGPS Test Scenario".

3. Set the GPS "State" to ON to enable the GPS signal generation.

The R&S Signal Generator generates an A-GPS signal according to the selected test

scenario.

2.8.7 Generating Assistance Data

(for R&S SMx/AMU instruments equipped with option Assisted GPS (R&S-K65) only)

The generic workflow for generation of assistance data files for A-GPS test scenarios is

as follow:

1. Execute "Set To Default" to adjust the instrument's settings to a standard set of oper-

ating conditions.

2. Enable the instrument to work in "Localization Mode Auto SV Selection".

Note: Do not use the "Auto SV Selection and Update" mode for the generation of A-

GPS test signals.

3. Enable the instrument to work in "Full Configuration" mode.

4. Set the GPS "State" to ON to enable the GPS signal generation.
