N7609B Signal Studio for Global Navigation Satellite Systems (GNSS)

Signal creation

• Supports real-time creation of multi-satellite signals for the GPS (L1 with C/A code) and/or GLONASS constellations with up to 32 channels for line-of-sight and multipath signals - Latest Enhancements
• Simulate stationary or moving receivers for up to 24 hours using stored scenario files, or use continuous scenario generation mode for longer scenarios
• Real-time adjustment of channel power or satellite visibility
• Create and edit custom scenario files or use continuous scenario generation mode with scenario generator options (requires Option RFP or TFP)

Hardware platform control and additive impairments

• Compatible instruments
• Control frequency, amplitude, triggers, markers, and more
• Add impairments such as multipath and pseudorange error in real-time while the signal is playing
• Add calibrated AWGN to control C/N ratio (requires Option N5106A-JFP on PXB, N5172B-403 on EXG, or N5182B-403 on MXG)

Automation and communication interface

• Automate test with SCPI commands
• LAN and GPIB control
• Remote capability using Remote Desktop Connection for N5106A PXB 

Other features

• Online documentation
• The N7609B can be integrated into the GS-9000 design verification system for A-GPS pre-conformance test
• Additional scenario files available for download Scenario Files

Create global positioning system (GPS) and GLONASS test signals

The N7609B Signal Studio for Global Navigation Satellite Systems (GNSS) allows you to easily create reliable and repeatable multi-satellite test signals for the GPS and Russian GLONASS systems to perform receiver verification tests. The application can provide up to 15 visible satellites for each constellation, depending on the scenario and satellite visibility. Additional channels (up to 32 total) 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, and impairments such as multipath and pseudorange error can also be added in real-time. With the addition of the scenario generator options for GPS (Option RFP) or GLONASS (Option TFP), users can create and edit custom scenario files to simulate stationary or moving receivers (up to 24 hours duration), or use the continuous scenario generation mode for longer simulations.
