The software also has the ability to add up to four CW interference signals inside the GPS, GLONASS or BeiDou bands for jamming tests.
With the enhanced N7609B software basic option, users can now create either single- or multi-satellite waveform files. Waveform-file simulation, a cost-effective solution for manufacturing, can be performed using the Agilent M9381A, PXIe VSG, E6607 EXT, X-Series vector signal generators, or the E6630 or E6640A EXM wireless test sets.
Several new intuitive information displays let users know the current scenario-playing status from a receiver’s point of view. Scenario information displays include satellite sky view, which shows the location of all visible satellites in the sky; power view, which displays the instant power of all visible satellites in a bar chart; and trajectory view, which displays the trajectory of the moving receiver in a scenario.
The N7609B software helps users create validated real-time GNSS signals that can simulate satellites for U.S. GPS, Russian GLONASS, European Galileo, China BeiDou, SBAS and Japan QZSS. It can create either static scenarios for stationary receivers or dynamic scenarios for moving receivers. The simulation can be for an ideal environment or for one with impairments, such as multi-path, pseudo-range error, loss of satellite visibility, satellite power change, ionosphere and tropospheric atmospheric attenuation, antenna effects, CW interference, or AWGN.
