For GPS and GLONASS testing, all key parameters for GPS signal creation are user-definable, including navigation data, space vehicle number, and Doppler (+/- 10 kHz). Additionally, the IQnav+ supports accurate CW signal output levels up to -60 dBm through a single test port connector. This allows a simple power meter to be used to verify fixture losses and overall system accuracy. It also provides a comprehensive test coverage for both the FM waveform generation and signal analysis.
