Easily create Global Positioning System (GPS) Test Signals
The N7609B application allows you to easily create reliable and repeatable GPS test signals to perform GPS receiver verification tests. For R&D and GPS verification, this application can provide up to 15 visible satellites, depending on the scenario and satellite visibility. Additional channels are available for adding multipath signals. The power level and visibility of individual satellites can be changed in real-time while the signal is active. The ability to simulate stationary and moving GPS receiver scenarios and generate and edit custom scenarios provides for a flexible and powerful GPS receiver test solution.

The GPS signals created by the N7609B allow users to perform the following typical GPS verification tests:
- Time To First Fix (TTFF)
- Sensitivity (acquisition and tracking)
- Location accuracy (relative and absolute accuracy for both static and moving GPS receivers)
The GPS test signals that are created for these tests must also include signal impairments for thorough testing of GPS receivers. The N7609B has the capability to create and transmit impairments such as multipath signals, loss of satellite visibility, and ionospheric and tropospheric atmospheric attenuation. The ability to add these impairments provides a flexible suite of signals for full verification of GPS receivers. Versatile and high performance RF signal generator
The GPS signal is generated in real-time by the N5106A PXB baseband generator and channel emulator. The PXB support interference testing with configurations for generating 2 independent signals, or generating and summing 2 baseband signals into a single RF output. The versatile PXB platform, combined with the E4438C ESG vector signal generator or N5182A MXG vector signal generator, is capable of creating signals for a variety of today’s wireless standards such as LTE, Mobile WiMAX™, W-CDMA, GSM/EDGE, 802.11n WLAN, and digital video.
