Coupling: Visible with the Capability selection of Basic Single Satellite Waveform and Basic Multi-Satellite Waveform.
Click the Generate icon to generate a waveform based on the Constellation and SV ID properties (SV ID does not apply to GLONASS). Alternatively click Control -> Generate to generate the waveform.
Coupling: Visible with the Capability selection of Basic Single Satellite Waveform and Basic Multi-Satellite Waveform.
Click the download icon to download a pre-generated waveform based on the Constellation and SV ID properties (SV ID does not apply to GLONASS). Alternatively click Control and then Download to download the waveform.
Choice: Basic Single Satellite Waveform | Basic Multi-satellite Waveform | Advanced Real-time Signal Generation | Advanced Real-time Signal Generation Pro
Default: Advanced Real-time Signal Generation
|
Selects a pre-generated single satellite waveform file and downloads it to the instrument for playback. |
|
| Basic Multi-Satellite Waveform | Selects a pre-generated multi-satellite waveform file and downloads it to the instrument for playback. |
|
Loads in a scenario file and generates a real-time GNSS signal, or provides continuous real-time scenario generation based on the Scenario Generator node settings. The Scenario Source selection determines whether to use a file or continuous real-time generation. |

Select the capability of GNSS signal simulation. Basic mode generates and downloads user defined single satellite waveform or multi-satellite waveform to instrument for playback. Advanced mode plays real-time navigation signal based on user selected scenario file or static signal based on satellite settings. Advanced Pro mode plays real-time GPS L1+L5 navigation signal with real-time scenario generation. |
Select the capability of GNSS signal simulation. Basic mode generates and downloads user defined single satellite waveform or multi-satellite waveform to instrument for playback. Advanced mode plays real-time navigation signal based on user selected scenario file or static signal based on satellite settings.
Enter an alpha-numeric waveform file name. The maximum name length is 23 characters.
Choice: GPS | GLONASS | Galileo | Beidou | SBAS | QZSS
Default: GPS
Coupling: Available with Basic Single Satellite Waveform as the Capability property selection.
Select the constellation for the basic single satellite waveform.
Range: 1 to 32 for GPS, 1 to 50 for Galileo, 1 to 37 for Beidou, 120 to 138 for SBAS, 193 to 197 for QZSS
Default: 1
Coupling: Available with Basic Single Satellite Waveform as the Capability property selection and the Constellation choice being a selection other than GLONASS.
Select the SV ID for the single satellite ARB waveform in the specified constellation. This is not applicable for the GLONASS constellation. When switching between constellations, SV ID is clipped to the limit.
Range: –7 to 6
Default: 0
Coupling: Available with Basic Single Satellite Waveform as the Capability property selection and GLONASS as the constellation choice..
Select the frequency channel to transmit the GLONASS signal. This is only applicable to the GLONASS constellation. Changing frequency channel changes the Frequency under the Instrument node.
Click '+' on the left to expand dynamic parameters.
Set the relative dynamic pattern between the satellite and the receiver.
Choice: Static| Constant Velocity| Constant Acceleration |Sinusoidal
Default: Static
Select the dynamic pattern for single satellite waveform.
With the Capability selection of Basic Single Satellite Waveform, four types of dynamic pattern are provided to simulate the relative range between the satellite and the receiver- Static, Constant Velocity, Constant Acceleration and Sinusoidal.
Range: 0 to 40000 km
Default: 0 m
Enter the initial relative range between the satellite and the receiver.
Range: -20000 to 20000 m/s
Default: 100 m/s
Enter the initial relative velocity between the satellite and the receiver.
Range: -500 to 500 m/s2
Default: 10 m/s2
Enter the initial relative acceleration between the satellite and the receiver.
Range: 1 to 50
Default: 1
Enter the number of sinusoidal cycles in the waveform for sinusoidal dynamic pattern.
To configure the navigation message, click '...' on the right side to prompt the Data Setup dialog box
Range: -144 dBm to 0 dBm
Default: -130 dBm
| For Advanced mode |
This property sets a reference power level on instrument's front panel. Power levels of all the satellites and interference tones will be relative to this reference level. It's recommended to set this value to the possible highest power level of individual satellite or interference tone across the test. |
| For Basic modes |
This property sets the power of each satellite for equal power control; sets the power for the satellite which has the maximum power in the first record of the scenario for range-based power control. |
Range: 0 dB to 100 dB
Default: 0 dB
Enter the attenuation value of the external attenuator if connected to the instrument's RF port.Then the external attenuation will be compensated, which means the amplitude of the instrument output will be set to the sum of Satellite Power and external attenuation.
Range: 0 to 50 MHz
Default: 4 MHz
Enter the sample rate for the single and multi-satellite waveform.
Range: 0.001 to 1000 s
Default: 6s
Enter the waveform length in second.
Display the total sample points of the waveform.
Choice: Start | Pulse per second | Pulse per millisecond
